CK3 - Vulkan - Animated Characters frame drops & stuttering

[P3Persona]

Hello all,

1st let me introduce my setup.
I play on 5800X, 3080 & Ultra-Wide 3440x1440p. And play on Linux. I own all the DLCs and currently play without mods.

For quiet some time I was keen to try Vulkan either on Proton on Native.

However when I switches from OpenGL to Vulkan (Native) or using Proton from DX11 to Vulkan, the game menu started to lag and stutter massively. On map in game it was kinda OK (with small visible performance loss), but when going to court room stutter appeared again.

I tried to play with settings, and interesting enough two settings looks like mitigate or completely get rid of it.


Portrait Multisampling
If this option is set to 2 from 8, the gameplay on MAP is smooth as it was before switching to vulkan. The game menu still stutters and lags so does as well court room but its significant improvement.


Animated Characters
If this is disabled, no matter what Portrait Multisampling you choose, all the issues from above are gone. Game is butter smooth in menu, on map and in court room.

I tried the above settings on native as well proton on several versions and the results are the same.

Did anyone have or seen similar behaviour?



NOTE: If anyone has similar issues disable Animated Characters this will make the game playable for you on Vulkan.

Switching off animated characters has finally made this game run buttery smooth. I have a 5950x and 3080, been looking for a solution for ages. Thanks heaps

I am glad it helped you.

Even thou lowering Portrait Multisampling helps a bit it is still not fully playable as it should if Animated Characters are turned on. (I am not sure if this problems is as well for Windows, cant remember as I switched to Linux 3 months ago)

Currently the only way at least how to play with Vulkan (Native or Proton) is to disable the Animated Characters , this will bring the performance back where it should be.


However the question still remains why there is such a HUGE performance hit when Animated Characters are enabled.

I've had the same issue for months now. At least turning animated characters off works.

Glad to hear it helped you.

I did as well report this issue as a BUG on CK3 discord if anyone can please give it "AGREE". The mods scrub the BUG section on weekly basis and sent it to Paradox QA.
