Doesn't run properly with default configurations
gamemoderun mangohud %command%

After the last update just broked
BROKEN

Works great
No tinkering needed
Small artifacts with water reflections + lagspikes (laptop gets confused on wether to use the iGPU or the dGPU and keeps switching midgame. Somehow only does that on Xorg, Wayland fixed all of the above)
Fullscreen works half the time. Black screen.
prime-run %command%
All works perfect
Game runs great on my rig. Installs and starts up really fast. Great experience on latest proton.
Same performance on both Windows and Linux, the game is still in early access/alpha
High CPU usage
Just deselect full screen in the configuration tool.
I had to deselect full sceen in the configuration tool or the game would not play.
I can get into the configuration menu where I set it to windowed mode and turned down the settings but it still doesn't start.
After disabling fullscreen mode through the configuration options, the game launched without issue and played great!

Disabled fullscreen
Works after disabling fullscreen

The game is working pretty well without issues so far, although I'd say that performance was sub-optimal while playing on RX580 @ 4K.
- Run Ostriv configurator and disable fullscreen mode
- Run Wine configurator from console (given command is for default Steam intallation & Proton 5.0, change your paths if your differs)
WINEPREFIX=
/.steam/steam/steamapps/compatdata/773790/pfx/ WINEPATH=/.steam/steam/steamapps/common/Proton\ 5.0/dist/bin/wine winecfg - Go to "Graphics" and select "Emulate desktop", write your screen resolution
- Press "Apply" and exit

Only problem problem is fullscreen. Game runs perfectly when played in windowed fullscreen.
Launching game in fullscreen causes screen to flicker once then game crashes.
Launching in windowed mode is successful with no performance issue.
Uncheck fullscreen in game configuration menu (outside the game) to start in windowed mode.
Need to disable the fullscreen mode in the game configurator before launching the game
Does not launch

Works great after "fullscreen" is disabled in the options.
Only windowed fullscreen works, game doesn't start if fullscreen is enabled in the options (enabled by default).

Had to launch the configuration tool first and disable full-screen.
Full-screen must be disabled.
