We (Riot Devs) are aware that some Players are experiencing a bug where the frame rate of League or TFT drops suddenly somewhere between the 5 to 10 minute mark and stays low or erratic for about 5 minutes or so. We have been unable to reproduce this issue internally, so we’re reaching out to you, the players, directly to try and identify the cause of this issue.

If you are experiencing these symptoms, please respond with details in the following format;

  • CPU:
  • GPU:
  • GPU driver version:
  • Reproduction rate: (eg every game or once every 10 games)

Optionally (you don’t have to do these, but this information may help)

  • What overlays are you running (Blitz etc)?
  • Did running the game in DX9 mode help? (You can do this via settings/Game/Prefer DX9 Legacy Mode)
  • Did running with SMT/Hyperthreading turned off help? Y/N

Additionally, if you can send me the .rpd file found in "League of Legends/Logs/Performance Logs/" just after you've played a game in which you experienced this slow down, that would be awesome. (The rpd file stores per frame performance information for the last game played. It will really help diagnose this problem).

Thanks in advance for your help with this. Hopefully we can finally get to the cause of this and provide a fix for you all.

[Edit] Let me just emphasize how useful RPD files are for identifying this issue. If you can, please, give me your RPDs!

[Edit2] I'm looking for information on JUST the case where there is a consistent degradation of performance after about 5 min into game, and for a few minutes after that. Not any and all random FPS drops.

I haven't played a game in awhile (2 weeks or so) or I would include logs but hope this helps some!

If so, then that is by design.

You can fix that by adding MillisecondsToSleepWhileSuspended=0
to the [General] section of your game.cfg file (found in League of Legends/Config/game.cfg)

Awesome! An RPD! Thanks!

I had a look at that and there is no unusual slow down in that game. Maybe your last game was ok?

There is a slight slowdown at the start due to focus being away from the game, but the rest of the game is running at around 7ms per frame (around 144fps) with the occasional drop to 10ms (100fps).

Thank you for that RPD.

The issue you're having is a separate one. You're running at about 60fps for most of the game, with slowdowns to around 20fps. Your CPU load is constantly around 70%, occasionally hitting 100%.
Your GPU is doing OK, but your CPU is really struggling.

Which is not surprising because your system is below the minimum spec - we recommend at least an i3-530 (2.93GHz). Sorry. Time to upgrade?

It doesn't look like you're experiencing the issue I'm looking for here, but here's what I saw in that game. You started with a decent frame rate (144+) for the first couple of minutes, stuck at around 100fps with drops to 80fps at points (probably team fights). What is odd is that your CPU load is quite high throughout the game, running at around 70% (up to 100% at times). It should be half that.

Did you have anything else running on your system at the same time?

Can you give an example of this with expected fps?

It doesn't necessarily show up as a visible FPS value being low as the FPS calculation is an average over a few seconds so even quite frequent spikes can missed due to the averaging process. This problem feels really bad, quite choppy as not every frame is bad, but just enough are bad enough to make it feel bad.

At least that's from the feedback I've had and from the few RPDs that show the issue.

Yup. That's the bug I'm chasing. And I suspect its AMD specific (might not be their fault, but it is evident on their HW).

Out of a couple dozen RPDs, I was able to identify 8 that showed the particular performance degradation that we're chasing. I'll be using this data to discuss this problem with some hardware vendors and between us we might be able to work it out.

I may be getting in touch with some of you over the next week for some more data one this problem.

Additionally, I'll be investigating a couple of other common fps issues that have been brought up in this thread. Hopefully we can fix a few existing problems now.

We do have Telemetry. Lots of it. But as I mentioned in another comment, this performance degradation hardly even shows up in our FPS meter, let alone in our End Of Game performance metrics. And if we can't detect the issue, then we can't filter for the hardware affected. Hence the request for RPDs where we do have every single frame logged.

Even that second RPD indicates network issues. Your overall speed might be fine, but if you're getting errors that require resending, we'd see issues like you're getting. Are you playing over WiFi or wired connection over Ethernet?

As for an update, we are currently purchasing some of the most common hardware that seems to be experiencing this slowdown, as we cannot reproduce this issue internally. If we can repro it, I'm pretty sure we can quickly narrow down the cause.

Testing a fix on PBE was inconclusive - some players reported that it worked, and some that it didn't.

GPU - Nvidia GT 710 2gb

GPU Driver Version - 27.21.14.5671

Reproduction rate - Every single game for a couple months now

Zero Overlays, DX9 Legacy mode doesn't make a difference, CPU usage doesn't change noticeably during the frame drop time, and the GPU is never fully utilized.

I honestly assumed it was just my potato PC, considering my dated parts... But it runs great for the first few minutes, and I saw this post, so thought I might as well chime in and see about finding an improvement. I tried using the other (the better x4 750k) CPU for a bit to see if that made a difference since my CPU is the weakest link, but all it does is increase the early framerate to 150+, after a few minutes it experienced the exact same frame slow down.

Edit: If there's somewhere specific to send the RPD file I'd be more than happy to after I play a game, just let me know where to drop it.

It could just be your potato PC. The more that happens in game, the slower it gets. If you can send me an RPD file I can have a look and see what’s going on.

Game still is fps dropping after couple of minutes, not that harsh as it was, but still. Its not resolved Tony

The potato comment was in response to a player saying it might be their potato PC. And looking at the HW they were running on, they are using a system which is just below the min spec that we recommend. So, yes, the game should run slow on that system.

If you are feeling that your game is still having the dramatic slowdown after about 5 minutes, then please send me your RPD and I can then confirm that you are having that same issue.

You're first 10 or 15 minutes are pretty much OK, running at around 140 to 100 fps. After 15 min, I'm seeing a weird oscillating frame rate, from 140 to 60fps, every half second or so.

This particular problem was only really noticeable on those systems, so there is no 'fix' for the other systems, as it wasn't a problem there. If you are seeing performance issues, then it is caused by something else.

One issue I'm seeing come up again and again is "My game starts at fps, but then drops to fps later in the game". This is expected behaviour. We do not maintain a fixed frame rate for League/TFT - we let the game run as fast as it can on the machine you're running it on. If you want that, then use frame capping.

Of course there are other performance issues and we are addressing those, but those are either incremental improvements (changes so small that you won't notice individual improvements but overall there should be gradual improvements.) or are big changes, reworking core parts of the engine/game loop which require significant effort. We do intend to do both of these. The trick is that we're also adding new content and functionality, its hard to add things and still make everything faster. But we're working on it.

The RPDs I'm getting through this post have been very valuable. I might do another call out next year for generic performance issues.

The issue is resolved. You are not experiencing that particular issue. You are seeing something else.

From your RPD (thanks for that - without them I'm blind), your frame rate is pretty good most of the time. But you are experiencing seemingly random spikes (including a massive 5 second stall near the 30 minute mark). Many of the spikes appear in the first few minutes of the game, but you started alt-tabbing around the 20min mark - why was that? You had a couple 60ms spikes just before that - did they cause you to alt-tab out? How would you have described the frame rate? Are you capping your frame rate? To what?

I can try uncapping my frame rate if you think that will help. As I have a 120hz monitor I thought capping at 244 was fine but getting several drops/stutters is frustrating

Thanks for your reply appreciate your insight here happy to assist with any further info or details

There is something funny going on and I'm not sure what it is yet. I suspect something is off with the frame capping (which would be our problem). Try turning that off and see how you go - are you using vsync? Turn that off. Maybe try capping to 120Hz so it matches your monitor.

Let me know how you go - I can't do much at the moment as I'm on break, but if we can lock down a repro/trigger I can set it up top be fixed when I get back.

Could you take a look at below? I have logged it with Riot support but not getting a lot of traction, I have performed a clean boot and removed overlays but not getting the results I hoped for.

CPU : Ryzen 7 6800H

GPU: RTX 3060 , Latest version 527.56

Reproduction rate: each game

What overlays are you running : None, suggested to turn off

Did running the game in DX9 mode help? : It did not help

Games start up and hitting 200+ fps on medium settings, then slowly move towards 110-160fps range. I would expect this to be much more stable and higher based on above specs. Would be great if you could take a look at it.

That's the same rpd that Raggou sent - you'll need to send me yours if you need me to help.

But, current expected behaviour for League is that the frame rate will decay as there are more objects in game (Minions, buffs, etc), so as the game proceeds, it will get slower. 110-10fps sounds about right for your system at end of game.

What frame rate would you be happy with?

I was expecting to hit same fps as valorant, there I can run everything on max setting and hold 200fps+ without a problem.

Also some extra feedback I got through the ticket:

"There is a wide-spread issue for players who have Ryzen CPU's, which is causing them to drop a lot of frames. And indeed our teams are aware of this and working on it as we speak. "

So it seems that League is aware of it and are working on it? :)

That's better! Yeah, you seem to be experiencing lots of 30ms spikes and they pretty much all seem to be due to network processing. Are you running via a wired ethernet connection or WiFi?

I suspect that the issue that Player Support is talking about is the one that we've just fixed - not the one you're experiencing.

[Edit] Regarding constant 200fps - I doubt that will happen anytime soon. Valorant is a very different style of game. Most of its processing is rendering, with only a few characters on screen and no real AI to deal with. League has well over 1,000 objects live at any time, all requiring updating and synchronisation across the network, most with their own particle effects. Getting all that, plus rendering, to happen in less than 5ms is tricky. Don't get me wrong - we're aiming for that and we have some things planned for the new year, but I don't expect that right now. Note that your system is behaving badly, if we can fix that then your games should feel much better, even without hitting 200fps reliably.

Hmmm, not that I am aware off. When I play it should be consistent at 12-15 ms. I am running a wired cable from a wifi booster.

So it would be possible to hit valorant at 240 plus fps through the same connection but with league be around 130 fps?

Yeah. It should be expected to run Valorant at a higher reliable frame rate than League on the same system.

Regarding your network - I'm guessing (I have to guess as I don't have enough information to know for sure) that your network might be switching endpoints every few seconds, causing a lag spike when that happens. I need to add more data to the RPDs to know for sure. I've seen it with some other players too, so we (Riot) need to figure out how to best deal with this.

Thanks for the help

Your overall performance is normal for your system. You are seeing spikes however, and that is not normal. The spikes seem to be due to the CPU waiting for your GPU, stalling for about 80ms. The spikes are not related to League, I'm not sure where they're coming from.

you have to install / move the game on a mechanical HDD, no matter the path, and the fps issues will disappear, you will have drop fps issues if you install the game on an SSD or an M2, which I tested, but with a mechanical hdd you will have spykes at 100 fps for only a few milliseconds, then they return to normal as you set them.

it will probably be something I/O related

.rpd file

https://drive.google.com/file/d/1Qwqf53L9GyLjvAVPfUfjpyL5weDl5aMh/view?usp=sharing

last 4 game is : 1HDD 7200rpm, 2M2, 1HDD 5400rpm,

the game work better in hdd 7200rpm, in 5400rpm you will have more spyke than fps, while with the 7200 they are rarer, they happen 3-4 times a game

That's really odd. The SSD should always have a faster seek and load times - there must be something pathologically wrong with access patterns from the SSD. I'll flag this as a bug and see if we can figure it out. Do you have an RPD from when it was running on SSD for me to compare against?

You also said this is not the same issue as the second-or-so-long stutters. So you are aware of that one too and will be resolved? Or is it something not related to LOL? That started happening after I updated my BIOS and moved LOL to another harddrive. It happens once or twice a game but quite badly. I see that the frame freezes when damage popup is shown (as my E approaches anivia). This example is NOT THAT BAD, there are much worse examples, but I didn't manage to clip that.

Yeah. Its not the cost of rendering the minions that is the issue, its the cost of pathfinding and logic for the minions. So they don't need to be on screen.

CPU and GPU at 10% sounds about right (depending on hardware). LoL is not GPU limited, its is CPU. And if you have lots of cores (which you do) then LoL will run one core at 100% and a few at lower percentages, which will translate to about 10% CPU.

So you moved your install to another drive? How fast is that drive? If LoL loads something mid game (which is bad, it shouldn't do that but does sometimes happen), then it could stall the frame while that load happens.

Okay, I moved it back to my SSD just to be sure it wasn't caused by this. Turned of SMT. Now, after rewinding 10 minutes (not locking them up), I am at about 135 FPS looking at them and 160 when I am not. Seems fine now. I am going to try ranked and will report back if the problems still happen. I always thought the minion position is done strictly on server side, as they stop when you disconnect from the internet for example.

Don’t turn off SMT. That was only to fix a bug which is no longer in the game.

https://drive.google.com/file/d/1DzIWZvON8-kpuTFEnEQ3yTSEZYNB6yPx/view?usp=share\_link

No. The game doesn't lock to any specific cores - we let the OS move the process around to whatever core it sees fit (there are various reasons for that - power/heat management being one of them). The graphs you see there are averages of CPU load. If you locked the Lol process to one core, you'd probably see it hit 100% then (but that wouldn't make the game run any faster)

The issues started around 1year ago, before that I always ran LoL without any issues on highest settings on 240+ FPS. Would love some help, since I am suffering and I feel like I tried everything. Checked hardware, deleted windows and played LoL only with drivers and nothing else installed on PC, had FPS specialists look over it, updated bios, and what not... pls help :(

What seems to be the issue? You are running at a pretty solid 7(ish) ms per frame, with a few (rare) spikes. So, around 140fps. This is pretty normal for your CPU. You are running with frame capping on which will artificially limit your frame rate. Is that intentional?

I doubt you could ever run an entire game at 240fps - it would start at that rate, but would slow down as the game progressed.

Can't recall experiencing a continuation of the issue when I completely shut down PC and started up, however still had issues when I restarted.

Also per the last game and another that i've played, it didn't allow me to reconnect to the match and brought me back to the lobby as if no game was in progress (I doubt the game was over at that point in time as attempted to log in from another device immediately). This is inconsistent though as I have been able to reconnect to matches when the FPS issue occurs and I need to shut down and restart my computer.

With regards to the FPS issue this tanked to literally 1-10fps from max screen supported frame rate.

Most of the time you game is waiting for 16.6ms per frame to hit the 60fps cap you've set. If you remove the cap, you should be hitting 100fps in a lot of places. You will still get some slow down in places, but your frame capping is just making things worse. Try with frame cap off and if there is still a problem, send me the RPD.

Yeah. I know. The players here want to play and can't due to performance issues. That sucks.

Part of the problem is expectations. League will not run at a constant frame rate (unless you pick a low frame cap).

But the other part of the problem is we keep adding in new stuff to the game, and new stuff means more processing which means a slower game. So we need to keep optimising. It's tricky.

Can you please acknowledge the fact that people have been having fps issues besides the one you fixed a month ago? I have had randomly unplayable games since the beginning of last year. I have a hunch that its an issue with the way windows interacts with the league client, maybe start there.

I have repeatedly acknowledged that there is more than one frame rate issue with League. And there will always be - this game releases every two weeks with new code and content, and problems will slip through. We do our best to test for these, and we fix what we find, but it is impossible to test for every possible issue.

As for the League Client being the issue, there are options to shut it down on lower spec machines when playing. And hunches don't help - data does. If you have an issue, send me an RPD. The posters on this thread have already highlighted some serious issues that we're chasing down now - all because they took the time to help with an RPD.

PD: I have tried all configurations, drivers and performance profiles.
It's something that already has me frustrated, my pc can give a lot of fps and in LoL it goes down to 70 and then it stays in that range regardless of the quality it has.
Another thing I want to add is that my rtx is 125w, but yesterday I installed cpu-z and it tells me that it is 80. Until then I don't know what to do, because the manufacturer has said and in the driver information that it is 125w, I don't know if that is the possible problem.

Are you Alt-Tabbing out on purpose? Looks like you did it 50 times in that game. Either that or you're losing focus for some other reason.

The problem has been resolved. If you're still having issues, then its something else.

The RPD you gave me showed a PracticeTool game, where you did something at 27 seconds into the game that caused a significant slowdown, after which, the frame rate was decent again. I can't tell what caused that, as I don't know what you did. Do you have an RPD of an actual game?

Looking closer at the data, are you running on a 175Hz monitor? Because for the first 26 seconds, your frame rate is limited to 175, even though it should be just running as fast as it can. The CPU is stalling, waiting for the GPU for multiple milliseconds. For some reason, it looks like your system is frame capping itself to 175Hz. Maybe even forcing a VSync, even though League isn't doing that. See what Monitor and GPU settings you have in that area.

A description of what you are experiencing would be handy. From that RPD, it looks like you are losing focus a lot. Are you alt tabbing out from the game repeatedly? For the most part, the game is running well over 100fps, just when the focus is lost, it drops back to 60fps.

I can't tell if you are doing the focus switches or if its a League bug.

That is interesting. Thanks for that. It would explain why your GPU is oscillating between taking 1ms per frame and 5ms per frame. It's probably dropping back into a lower power state - League is CPU limited, so a High end GPU will render League in very little time.

It doesn't need it. It is doing all the rendering it needs to do in between 1 and 5 milliseconds. Then it rests, waiting for the CPU to ask it render again.

Maybe it is the oscillation of power states with this new GPU. I don't know. Usually its the CPU which is the bottleneck, as League doesn't push the GPU very hard.

I don't see an issue with the performance of that game. Your frame rate is around what is expected for the CPU you have. Can you describe the issue you are experiencing?

Also, I see that your GPU seems to be stepping between states, sometimes slowing down and speeding up. Are you using a 3rd party GPU tool like Rivatuner or Afterburner?

Waited for the new season/ patch to test the game out, I am experience massive frame drops; I've tried capping at 120 to keep it playable, but I'm seeing a lot of moments where I drop to the 80s or lower, and overall inconsistent frames. Please let me know if my RPD file looks normal or irregular.

All of your frame issues seem to be GPU related. You are getting consistent GPU spikes up to 12ms. Are you using any 3rd party tools to optimise your framerate?

no overlays, DX9 is mandatory because is the only way to keep more than 45 fps after alt tabbing.

95fps worst case is pretty good for your hardware. You will never maintain the frame rate that you get at the start - not much is happening then, so of course the game is much faster then.

The DX9 thing is an issue though. Alt tabbing should have no impact on frame rate. An RPD would help me identify the issue.

Once I restarted I had a stable game (140-144hz consistently).
Last time this happened in a ranked regular league, I did restart but it didn't fix the frame issue so it seems I was fortunate this time.

Please see the linked file below for the game:

What frame rate issue are you seeing there - or is this the game which ran well? It looks like you're frame capping to 144, and for the most part you are maintaining that frame rate. There are consistent microspikes though - couple of times a second the frame time jumps from 7ms to around 10ms. This is very different to what we saw with your first RPD.

Hope it helps :)

That is expected behaviour. 120 to 160 fps is a good frame rate.

Well, that sucks. If its what I think it is, you could try and edit your game.cfg file - add

"MillisecondsToSleepWhileSuspended=0"

in the "[General]" section. That might help until we fix that bug.

(I locked it to 190 with Gsync to see if it would help, I have a 165hz monitor so maybe it needs to be under the frame rate.)

If you want to frame cap, only use the in game capping. It seems like anything else can cause stuttering.

Yeah that was only a short term test, I now have it at 200 and it still seems to drop to 199 and stutter/microstutter and it's actually really debilitating in team fights.

Do you need to frame cap at all?

Yeah, if I have it on uncapped my fps are all over the place.

What do you mean by “all over the place”? Is it a problem if the fps is too high? Do you have vsync off?

It ranges any where from 400 to 300 and feels really bad to play, the drop in frames is noticeable and stutters occur. I’ve tried with v-sync, should I try with vsync+gsync and uncapped frames again?

Yeah. Very high frame rates suffer from a floating point precision issue, causing some jankiness. I would frame cap to 240 and run without vsync or gsync.

Thanks. All this information helps. I appreciate it. If you can share an RPD, that'd be really helpful.

Hi riot devs, i believe that you guys are looking in the wrong areas to resolve this issue. I have a career in cybersecurity and have noticed that lolbins (windows native executables) are being executed and run while in game and suspect that hackers are able to make connections into players computers to do this. Over the past several weeks I noticed that this happens only while in league of legends games or TFT games even with a fresh install of windows and can be reproducible every time. I have tried everything under the sun to prevent this from happening but cant figure out how they are able to make connections into players computers. This also results in me going from 240 constant fps in game until they have a foothold into my computer and will stay around 130 fps the entire game after minions are spawned. The only time i was able to resolve myself of these issues was block all connections being made out from riot executable minus the legitimate ones using binisofts windows firewall control.

I'll check it out, but the symptoms you are describing are expected behaviour as far as frame rate is concerned. The FPS will drop after minion spawn and will stay lower (and get even lower) as the game progresses.

I wonder if some in game data reporting is causing this. Which connections did you enable/block?

How many CPU cores does this game use? From the looks of it, system resources are underutilized while fps dips.

It will use 1 core to 100%, another core to about 20% and multiple others to a lesser extent. Most players run at about 18% load, but there are some that will hit 100% (depending on hardware of course).

Game starts at 200 fps, but falls down to consistently mostly between 90-115 fps. This gets worse the more the game progresses, and I have even seen myself drop below 60 in some teamfights.

Have tried most fixes, but to no avail. Only thing I've yet to try is reinstalling league and or formatting windows (won't do that).

Your GPU performance is all over the place. Are you running a 3rd party frame capper or GPU optimiser?

What happens when you frame cap to something other than 120fps? For example, 240? You should be able to run at around 144 for the most part.

Hello RiotTony,

GPU : Zotac 1060 GTX mini 6GB

RAM : 16GB 2.7GHz Dual channel

SSD: standard 500MB read/write

Running at 1920x1080

Tried all above modifications, FPS drops happen all the time, Game starts with 300fps, then drops to 110 over the course of 3 min.

Is it possible to list all the game.cfg commadns that can be used in the given file,

The command "MillisecondsToSleepWhileSuspended=0" helped me with altabbing,

Now the current issue is that the game just stops using rescources, CPU and GPU usage drop below 10% at some moments, while it shgould be above 40% at least. I've tried reinstalling GPU drivers rolling back BIOS updates ETC. Adjusting the Nvidia settings doesn't help,

If anything else is needed let me know.

Your hardware should run at an average of 110 - 120 fps. Which you seem to be getting already. Frame drop over the length of the game is expected.

Your CPU will never hit 100% as we don't fully populate 8 threads to 100%. 40% would imply at least 3 fully saturated threads - we don't do that.

Does your game drop to lower than 110fps for an extended period of time? If so, send me an RPD and I'll take a look.

Other than that, if you want League to run faster, you'll need a faster CPU.

That HW should be able to average 110 to 120fps. That RPD only contains data for 5 minutes of a game, I'll need more than that to help.

Although, your GPU seems to be spiking and taking longer than it should. Are you using 3rd party frame capping or GPU optimisation apps? What power setting are you running - if you're not running High Performance than your machine will be throttled by the OS. You're also running with Vsync on - that could slow you down depending on your monitors refresh rate.

https://we.tl/t-ZW1V1XBPlP

Here is the RPD that I've found , also if this line could be explained in some way
"***.***.**.** **** *****************************== ********" "-Product=LoL" "-PlayerID=*********" "-GameID=*********" "-GameBaseDir=D:\Riot Games\League of Legends" "-Region=EUNE" "-PlatformID=EUN1" "-Locale=en_GB" "-SkipBuild" "-EnableCrashpad=true" "-EnableLNP" "-UseDX11=1:1" "-UseMetal=0:1" "-UseNewX3D" "-UseNewX3DFramebuffers" "-RiotClientPort=*****" "-RiotClientAuthToken=**************"

I'm just curious about the frambuffer? It's not CPU related, as OC the CPU does not yield in more fps or a performance boost

That RPD is only from a practiceTool game of just over a minute long. Not much use to me - one from a longer game would be more useful.

What you've found are just command line args - the Frame buffers are just an internal thing in our engine. Its been there for ages.

I'm starting the match with 100++fps and then getting lower
RDP : League_prefDUMB.rdp

Yeah. That is odd. The only difference from Garena might be DX9 vs DX11 by default.

See if DX9 works for you, then let me know.

From that RPD, the GPU is running quite slow.

Yeah. That is really odd. Every second, there is a spike for a few frames. Those spikes are ruining your frame rate - if they weren't there you'd be running nicely. I can see where you've tried different frame caps, and that didn't make a difference.

I suspect something external is stealing CPU cycles? I dunno - this one's weird. Do you have anything running which does stuff once every second?

Reproduction rate: Every single match, around 3 minutes in FPS drop from ~170 to around 60-90 and game stutters like crazy. (this refers to both league and tft)

What overlays are you running: I'm using blitz but if i disable it, nothing changes

Did running the game in DX9 mode help? (You can do this via settings/Game/Prefer DX9 Legacy Mode): haven't tried it yer, im gonna update asap

BTW. I've got 2 monitors and the problem occurs especially after i alt+tab from the game, I'll check if cfg command helps with that

Yeah - that game looks bad. Do not try DX9, do not try SMT - they were only when trying to find a very specific problem which has since been fixed. Are you running any 3rd party GPU frame capping or optimisation tools?

That game seems to have had an issue with CPU load increasing from 10% at the start to 70% by the end of game. That normally implies that something else is running or your CPU is throttling itself.

Can't say exactly at what time happend, but had some huge FPS drops ( thot's how i ended up here), at one point i tought the game just froze..

Yeah. You had a 4 second stall about 6 minutes into game. And your frame rate is consistently bad. Are you running any 3rd party frame capping or GPU optimisation applications?

In 90% of cases, the performance is normal and stays at around 140+ FPS (144 cup). But in huge fights (in this log it is 15:58 minutes) there is a drop in FPS by about 30-40, which makes the game feel completely different.

That RPD only contains data for 5 minutes of a game, I'll need more than that to help.

Okay, but if all the problems occur after 5 minutes of playing?

RPDs give me a view of the frame times for the entire game. Which is why I need to see a full game (not practicetool) to be able to determine if you're experiencing normal or degraded performance.

I see your frame drop at 15 minutes - It's triggered by some large GPU stalls, followed by 2 250ms stalls, which seem to be primarily input related. The input is probably due to Windows events flooding the event queue after the stalls.

Try turning off Afterburner. It can play badly with League.

I get this same thing. game starts fine. Minions show themselves im still fine. Until i touch my mouse then i go from 144 fps to 80-90 and my screen appears to shake with each step. It's worse when walking up or down lane vs side to side which is why im lead to believe this is a vsync or refresh rate issue within league since it only happens in league.

I have tried with vsync off and vsync on. Neither fixes it. Which is why ive figured it to be a "inside of league" issue tht Riot needs to handle.

cpu ryzen 9 7900x
gpu 6950xt

i never have issues when im playing anything else. and i stream all the time while playing. Sometimes i can get a successful test run out of a practice match. But in any actual game, it stops working. but it doesnt stop as the minions enter my screen. it stops as i make my next move at tht point.

What do you plug your mouse into? Directly into your computer or via a hub of some form (a monitor for example)? And what is the update frequency of your mouse? (Polling rate?)

And, as always, RPD files help me diagnose problems. Without them I'm just guessing.

Hey Tony,

Thanks for the reply.

I do not recall using ani GPU frame capping or optimisation software. I use MSI afterburner a little bit to oc my gpu however I've been using it for a long time before game started behaving that way.

What are your suggestions about the CPU issue u saw?

Thanks in advance

Try disabling Afterburner and let me know if it helps.

As for the load increasing, that has to be something else running on your computer. League can't use 70% of your CPU - it doesn't utilise enough threads.

That sounds like you’re getting excellent performance. What makes you think 180fps is bad?
