Game crashes once the Unreal animations finishes
Not sure if it's a problem with the port itself or running the game with proton.
When launching the game, an error window will warn about audio and OS compatibility, but you can skip through it and the game itself plays with no technical problems.
Save data is deleted when the game is uninstalled. No Steam Cloud support.
Occasional stutter caused by shader compilation
Upon Launch of the game, I was met with an error window displaying two errors. 1) system OS was not detected 2) sound card was not detected
Latest SteamOS build on public Beta. 06/20/20
Bad
Both controller and mouse are problem here.
During the first time setup it gives a warning "no audio device detected" but the audio works anyway.
Runs perfectly out of the box. But with some fps drops, if you want a solid fps add PROTON_USE_D9VK=1 %command% to steam launch parameters, now it works at 60fps for me.
First time launching the game during the first time setup it gives a warning "no audio device detected", but works perfectly anyway out of the box. The performance does not scale much with quality settings, but with everything maxed including 8xAA I got around 50fps at 2560x1600 resolution without any stuttering.
Runs out of the box with performance (mediocre) similar to native. First time launching the game, there was a warning message "no audio device detected" but everything worked anyway. Not sure if this also happens the first time on Windows.
Flawless.
Runs great with vsync off. With vsync on, performance with max graphics is under 22fps.
Max Settings at 1080p and runs perfectly.
