[2021] Crusader Kings 3 - Huge FPS Drops/Stuttering

When you say "anymore", it was okay for a while before this happened? Is that right? Or it was like this right from the start?

Any mods involved?

What happens if you disable autosave, any different?  

Master Seat said: stuttering and fps drops from beginnen - after some fixes in my system it worked for a while and now its stuttering and droping frames every 5 secs again.

What nature of fixes in your system seemed to help?

Master Seat said: i played a game with auto saves every moth and it worked fine a few days ago

What change or update to your system occurred between when the game last ran okay and first had this problem?

Master Seat said: Are u the only tech-supp for that game ? I can also speak german if there is a german techsupport

We only give support in English here, I'm afraid. You are welcome to post in our German forum, but there is no official support offered there:

The thing is that the game itself has not changed between when you bought it and now. But you say it ran bad, then was okay, then ran bad again. So clearly something outside the game is causing this for you, something that changes in your system.

I've seen massive Windows updates downloading cause that kind of thing, but yours is up to date it seems.

I do see a crash in the nVidia software in that dxdiag so let's do a clean reinstall and update of that:
- uninstall the nVidia driver and all nVidia software
- reboot
- install the latest (Dec 2020) from here:
Download Drivers | NVIDIA - reboot again

THEN
do a full **clean** re-install:

- move any valued save games elsewhere
- "uninstall" in Steam-CK3
- manually delete both the Steam/SteamApps/common/CK3 AND Documents/Paradox/CK3 folders
- re-install game in Steam, run a Steam Verify when done.
- add CK3.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
In particular make sure there are no files or folders left under either the Steam CK3 or Documents CK3 locations, before installing again.

THEN unload GeForce Experience if it is loaded, and try the game again from the PLAY button in Steam.

Good luck with that!  

That other thread you posted in say they only get the issue when scrolling with the mouse, not using the WASD keys. Do you find that too?  

So you can just be sitting on the main game menu, and you see the fps reading drop down then recover every few seconds, is that the case? Without you doing anything on the mouse or keyboard?

If so that's pretty bad, but it's hard to see what could be causing that!

Does it happen in fullScreen and windowed modes?  

I doubt it very much, but you could do a clean reinstall again (as per post #7 above), changing your Steam download region before installing again so it comes from a different Steam server.  

Gidders91 said: Hi Andrew, I'm having a very similar issue it seems.

The game was running great since I bought it at launch, however today the FPS has dropped to a consistent 3 FPS when not moving! I've tried windowed, full screen, uninstalling and reinstalling but nothing seems to work.

Every other game I play is fine, as I thought it could be to do with my GPU. But this is the only game where the FPS has just plummeted

Was the above fixed? Is there a solution?

If it only happened in the last few days, it is not the game causing this to you as it has not changed in that time. Here's a clean reinstall:

- move any valued save games elsewhere
- "uninstall" in Steam-CK3
- manually delete both the Steam/SteamApps/common/CK3 AND Documents/Paradox/CK3 folders
- re-install game in Steam, run a Steam Verify when done.
- add CK3.exe to the exceptions list of your antivirus app; ESPECIALLY if you have Windows Defender, add it to the Ransomware "Apps Allowed Through" list.
- start the game with no mods active and test

In particular make sure there are no files or folders left under either the Steam CK3 or Documents CK3 locations, before installing again.

If it still happens, please make your own new thread and attach the info files you see me ask for in these threads, thanks.  

NGC_908 said: The game for some reason drops to 3-11 fps when you have a lot of troops on map, specially on African area, then, when you move the camera to another location and troops dissapear from the screen the framerate becomes smoother again, back to normal... I think that is a game issue more than other thing.

One curious thing: if you put the cursor over a province, the game becomes totally smooth magically.... until you quit the cursor again. XD

I don't know why this happens, but is clear that it's a game issue.

StMaurice said: Andrew,

This issue occurs when a player is mid-late game on their campaign when they have amassed a lot of territory and troops (including vassal troops running around).
It seems the game is not very optimized for mid-to late game, since the game runs like a dream when you stop your mid-late game save and start a brand new game.

Followed another thread last time I ran into this problem on a campaign and got frustrated enough to look for a solution and either it did not have the instruction to delete your ck3 folders in documents or i missed. will try this and report back. My last attempt without the deletion of the documents ck3 folder did not work obviously because I am running into the problem again late game.

It seems you both believe this is a game code issue, in which case we here in technical support won't be able to fix it!

Please post the problem in Bug Reports forum, if it's not there already, with sample saved games plus dxdiag.txt files to show what hardware you have.

Sorry for that problem!
