Works great, no tinkering needed.
Working perfectly out of the box.
No FPS drops using latest Glorious Eggroll. High CPU usage, but I believe it's java based, so that's normal.
Set launch option PROTON_USE_D9VK=1 %command% Otherwise the game is too laggy to play comfortably.
Even with the D9VK fix, menus are still a bit laggy when using a controller. Recommend using a controller for gameplay but mouse for menu navigation.
Runs and drives, but with very low FPS. You may be able to squeeze more FPS by changing the resolution to a small window, but it still wasn't good enough for me to play comfortably. The controls are sticky, sometimes continuing to move despite letting go of the key. The control issue may be a side effect of the framerate.
There's a few minor frame drops, but nothing terrible. Plays just fine.
debian unstable, AMD R9-290X, Debian Unstable. Doesn't even open.
Severe slowdown when hovering over any button in the interface, controls get stuck (as a result of performance jitter) when attempting to play. Unplayable due to slowdown alone, seems like it will work perfectly if that can be resolved.
Black screen, had to xkill.
Correct performance
