I’m on bazzite
this is my launch command:
mangohud PROTON_FSR4_UPGRADE=“4.0.2” MESA_SHADER_CACHE_MAX_SIZE=4G %command%
It runs so good, I use LACT to set my card just like I did in adrenalin on windows and i’m getting 190-200fps in the mouringstar and 144-200 in games, it’s so smooth it is unbelievable and I would say it felt like playing it properly for the first time.
I have no problem with the FPS. My problem is with Ray tracing with my RTX 5080…
It can work, but there is crashes from time to time.
Darktide is clearly one of the game that works really badly on my computer. To compare, Arc Raiders with everything on Epic (including Ray tracing) gives me a smooth experience (I see values for FPS around 240 fps) and with extremely rare crashes (I have got like 2 crashes in 100 hours).
DLSS works good for Darktide on Linux. You’re lucky that FSR works also great for you (considering the bug reports we see around this feature).
Sidenote: I have removed ray tracing from Darktide to be able to play without crash.
I was messing around with nvidia global illumination OR ray tracing on and although I could see a slight difference, its not worth the cost imo, I just use reshade filters and I get a very good quality image without either of them turned on
I have updated my launch command:
mangohud PROTON_FSR4_UPGRADE=1 WINEDLLOVERRIDES=“dxgi=n,b” %command%
I get FSR 4.1 in the in-game menu now
