Hello friends! I am back with another issue.
Recently I have taken on the task to get non steam games working on Proton. I have noticed that the performance is significantly worse with them on Linux then on Windows. More frequent stutterings and such. 100 fps consistently on Windows vs linux which it dips below 50 fps. Other “better performing” non-steam games get consistent micro stutters. I am using native steam because the flathub version because after installing dependencies with protontricks the game still would not launch.
The only possible thing I can think of is the games are on NTFS partition (yet steam regular games installed on it run just dandy). I dualboot with windows and access this particular drive between both os’. I am at a complete loss, any help would be appreciated oh Linux brotheren and sisteren.
Thank you!
(also the games drop audio consistently as well sometimes it wont come back unless I alt tab and come back to the game.)
Those micro stutters and lower performance for the non-steam games are due to shaders needing to compile as you play. If you play for a while and keep the same Proton version, they’ll eventually go away and performance will improve.
This has not been the case for at least a year or so thanks to graphics pipeline libraries.
Shader comp also only really manifests in frametime spikes, not generally high average frame times.
I assumed from the start this would be the issue. The mention of it happening to non-Steam games is the giveaway -
Steam provides pre-compiled shaders for the games they supply, non-Steam games have to build up their shader cache whilst you play.
Damn. Well this train will chug along then ;-;
EDIT: just tested and it seems performance just gets worse the longer I play.
EDIT 2: I lied it actually is betyer with another non steam game after playing for a while and restarting.
