Flawless
Worked smoothly for the entire story, no issues at all.
On Cinnamon, game starts on fullscreen but doesn't cover the taskbar. To fix, set it to windowed and then go back to fullscreen or borderless.
Sometimes the mouse would jump around.
Mouse gets a bit wacky at times and you need to fix the fullscreen each time the game is launched, but everything works aside from that.
When I got to the bridge, framerate was unplayable. After the third patch, performance was much better
Works out of the box using default Proton, did not encouter any issues
Game does have some traversal stutter (that also occurs on windows). Also like most UE5 games very demanding on highest graphic settings. Disable HW raytracing as it tanks performance and barely looks any different.
Game launches into a black screen. Waited several minutes to rule out loading time. Using proton hotfix it even crashed my WM
Tried a few of the most recent versions of proton to include GE and experimental
Fully playable. Works good.
I was playing on High settings (1080p) with enabled DLSS on Quality preset. Avarage FPS: 70-80
On my hardware, it runs smoothly and hopefully it will run just as well on steamdeck too.
