Howdy! Integrating NVIDIA Reflex was done by my team, Gameplay Integrity, for VALORANT. If you have any questions about what it means for VALORANT or how it works just let me know. We're super excited to roll this out to players!

NVIDIA does an amazing job of covering Reflex here: https://www.nvidia.com/en-us/geforce/news/reflex-low-latency-platform/

Overall, I thought they knocked it out of the park with Reflex and was happy to work with them to see this live in VALORANT.

Hello! Love the tech! Would a wireless mouse work on the new monitors to check latency? I have a Logitech G502 lightspeed

You'd need to check with Logitech about their support for Reflex Latency measurements on that mouse. I don't think there is a full list of supported devices released yet.

As I understand, for people who just want lower latency and not actual SDK, there will be a "nvidia reflex low latency mode" switch (provided it has a compatible card of course). Can you provide any ETA when this switch will be available?

The setting in-game will automatically become available (and default to on) in VALORANT when you install a compatible driver! The current release day for the driver is scheduled as Sep17th. VALORANT patch 1.07 already has the code to support the features! All you need to do is make sure you keep updating your NVIDIA drivers.

I have an nvidia card (RTX 2080) and a 240hz monitor. Assuming my mouse is compatible, do I need to buy new hardware to take advantage of reflex I game? Or is it simply an ingame setting that will reduce input latency?

I am willing to buy a new monitor and GPU but I don’t care much about measuring latency, I’d just like to know that it is as efficient as possible.

Reflex works as long as you have a 900 series NVIDIA card or better (2080 is better). So you'll be able to use it!

If you want to be able to measure your total input latency, you'll need a compatible monitor and mouse. However, that's only for MEASURING it, you get the latency benefit with any mouse or monitor.

Does it support any monitor or should it be 360hz?

It supports any monitor. However the higher the hz of your monitor the lower your input latency can be.

I just want to know if it's released yet and how to enable it, I just logged into my account in Valorant but didn't find any Nvidia reflex setting as well as in Geforce experience. I have an RTX 2060S.

Does it improve latency even when CPU bound? Aka anyone with a 1080 or better? The past implementations of low latency mode by Nvidia only worked if you were gpu bound.

It does not improve latency when you are CPU bound. I have a 1080 TI but I play with max graphical settings in 4K. There are still moments when my game becomes GPU bound. Good eye and understanding of though, you're right that this will mostly benefit GPU bound scenarios.

Brother I have one last question. I know particularly riot cares about their gamers a lot than other game devs out there and how they went on making better servers and anti cheat system. But having an in game setting that will only be useful to nvidia. How does that go with riot is it not like supporting one particular base where leaving another base go down a bit? Is not not unfair to let nvidia users to have little advantage over amd users??

For this, we definitely thought about the trade off. In the end though, the hardware you play on is going to give you an advantage. Players with 144hz/240hz/360hz monitors are going to have an advantage over those without. Players with better ISPs that give lower latencies and no packet loss are going to have an advantage. Players with high-end machines are going to have higher framerates. Players with gaming mice with higher poll rates and better sensors have an advantage.

In the end, our goal for VALORANT is to make the interface between you and the game as responsive and seamless as we can possibly make it. To that end we're happy to support any hardware or software features that reduce the friction that input latency causes between what your brain/body can do vs what we can represent in game.

We try to weigh the pros/cons of supporting any technology against fairness and accessibility. Honestly if this was technology only supported by the 30XX series cards we might have had a harder time justifying implementing it. However, a large number of players have access to NVIDIA 900 series cards or better so we felt in this case it was a fair advantage to give. This isn't about preference for any particular partner either. We're happy to help co-develop or integrate any technology that makes gamers lives better. I hope this tech shakes things up and more hardware/software developers start prioritizing input latency higher. I hope gamers get excited about it as well and start demanding better and better latencies.

Hey thanks for the reply! This probably isn't your area but I was wondering if you knew when the next software engineering internship opportunities would open up at Riot? :)

Sorry that's pretty far outside my area of expertise. In general, most of the interns I've worked with have been with us over the summer. However, I don't think that's always the case. I'd say keep an eye out on riotgames.com/careers for any updates!

If you're interested in the engineering aspects of reflex. I'd also recommend thinking about how frames make it to the display more and reviewing the graphs in the reflex article. We often talk about a game being CPU/GPU bound as if those are two binary options. The reality is that a game can be both CPU/GPU "bound" in a way. Simulation happens first, then render. The input latency is the sum of these two things, not the longest of the two if that makes sense. However, they can be partially parallelized!

does it lower the fps ?

No. The FPS stays the same.

Hey RiotBrentmeister I have two questions, first is it normal that I feel csgo way more smooth? This in term of fps and mouse responsiveness. (I have a ryzen 3 3300x and a 1050) (also it seems that the game has issues detecting my monitor, it says 1920 x 1080 when it is 1680 x 1050 and I need to use a software and kind of cheat to stretch my screen, because it f**ks up the display. I don't want to explain how I do it, so if I comeback to the game (I came back to cs) I can still play in decent conditions. (yes 4:3 stretched player models is still possible)) . Secondly, my screen is 60hz and I have always felt that my shot should hit in case like this : https://youtu.be/muvToLXJSks , but while watching my own replay I couldn't say it was the game fault, as it wasn't including all the input lag I play with. What I want to ask is, do you plan on ever having a way to include some of the input latency in the hit registration? Sorry for bad english.

I can't so for sure but a lot of the stretching software out there will add additionally input latency and potentially even worsen your framerate. I wouldn't recommend trying to use it. VALORANT will force a 16:9 or 16:10 aspect ratio, we don't support 4:3 if that's what you're trying to get by stretching. 1680x1050 should work as a 16:10 aspect ratio though so I'm not sure why the game is having problems with your monitor. What does NVIDIA control panel say about your available resolutions?

Hey thanks for answering, here is a video showing my native resolution is 1680 x 1050. And 1920 x 1080 in game always default to 1680 x 1050 but not like it should. Also even 1680 x 1050 is not what should 1680 x 1050 look like. https://youtu.be/Yg_zmaZPTb4

The other vid : https://youtu.be/xUDvIw_-67E Just shows 1920 x 1080 is not supported.

And for some reasons 75hz doesn't always work even if the game says I am using 75hz my screen says it's 60. This is one of the most annoying thing as there is quite a diff between 60 and 75.

Oh wow this is very weird. It looks like your monitor is reporting that it supports 1080p but it really doesn't. Do you know the exact model number for your monitor? It looks like an LG. You can locate it usually on the bottom of the monitor or in the top-left. I think I can see it in one of your videos but it's too blurry for me to read it. Some kind of PLAYTRON monitor but I can't read the code.

In terms of things to try in the short term is if you have a different connector have you tried using it? For instance, you're using HDMI so try using DVI. If you have another HDMI cable you might try using that as well. I have found certain HDMI cables can cause compatibility problems with certain monitors.

The fact that windows thinks the monitor mode is supported as well makes me wonder. Have you tried using a lower resolution and seeing if that at least centers the screen?

If you have a moment to answer a question I'd appreciate it.

I have an i9-9900k (OC'd to 5.0Ghz) and an RTX 3080, however I am not consistently getting over 280fps in comp games in 1920x1080p (to take advantage of my 280hz monitor) even when all other applications are closed and graphics quality at varying levels. In a custom lobby all alone I have seen my fps spike as high as 700 and not touch below 400.

I have been tearing my hair out trying to optimize to even get 280fps 80% of my in-game time.

My question for you is, should I be? Do you think with my setup its feasible to get 280fps in a competitive match 90+% of the time? Or should I just be patient for optimization updates?

We don't have a ton of data on this specific setup since it's so high end. I'm seeing an average framerate of about 256FPS in the data. So maintaining 280 is going to be tricky. OCing could maybe get you there but you'd have to maintain that clock rate rock steady with no dips due to thermals.

Honestly this is the first I've heard of the 280hz monitor. That's pretty neat. I'd heard of the new 360hz coming out and the 240hz but never seen the 280hz.

In terms of our optimization goals, we do hope to make better use of multi-core systems in the future. This patch did include a small optimization in that direction. We hope to have another small one available in a few months. Then start hitting the big hitters once we've found our stride. This isn't something that's going to be fixed overnight or even the next couple of patches but we're making steady progress. The number one priority here will be keeping the game stable from a perf/bug perspective as we make these changes. We're still trying to hire for the role too :)

It´s known that g-sync or v-sync adds input lag. Do you gain less input lag by enabling nvidia reflex in game and turning off all forms of display-sync options within nvidia control panel and on your monitor?

Yes the best settings for input latency would be: Reflex : On + Boost V-Sync : Off
