Hey guys,

im playing a few weeks now mainly on linux again. But whenever i play AC Unity the game do have some laggs and stutters every few seconds and today the graphic looks very bad, and there is some grain on the textures (with Ultra Settings). Are there some known performance tweaks out there? Cant find anything that is helping on ProtonDB.

My system: Linux Mint 21.2 x86_64 Cinnamon with X11, Kernel 6.5.0-21-generic, Mesa 24.0.1 from the kisak PPA

Hardware: Radeon RX 6950 XT, Ryzen 9 7950X3D, 27’ 2560x1440 with 144Hz

My Steam Startoptions: LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libgamemode.so mangohud %command% Using GE-Proton8-32

My whole system runs on a nvme ssd so i dont think that this should be a problem?

All my other games are fine (for what i see right now), except AC Unity and Star Wars Jedi Fallen Order. No problems with Hogwarts Legacy, The Witcher 3 and some MMORPGs.

Any help is very much appreciated.

    Have you tried regular Proton? Just to make sure GE’s patches don’t interfere here.

      I changed Proton to Proton 8.0-5 and it seems that it runs much smoother now! Thank you for the tip. But like i also mentioned, the graphics look grainy and bad (hope pasteboard is working here): https://pasteboard.co/J04DV6MLyjBy.png https://pasteboard.co/jw2C0cRoKIxU.png How can i get rid of this? Has this something to do with the shaders? I already disabled the steam shaders and re enabled it.

        I’m not familiar with the game or how it should look like but it is quite old and was considered quite intensive at the time which may explain some of the effects present here.

        I can give some general observations and tips though:

        • The fizzling you prominently see here exists to mask LOD (level of detail) transitions
        • LOD appears to be quite low overall; especially textures in the distance

        I’d google for LOD issues in AC:Unity.

      In the beginning, i used Proton Expermimental (i think) because of some problems starting the game. But i can check again and also try one of the stable versions.
