Worked out of box
The game worked flawlessly out of the box
PROTON_USE_WINED3D11=1 %command%
The game would launch but wouldn't display anything until I set the launch option listed in the report.

Random pauses bug
The game suffers from a weird bug - game pauses itself randomly. Happens to me on rare occasions on Windows desktop. And happens to me frequently on Steam Deck, BUT only when I use KBM config.
The issue seems to dissapear, when
- I use the official layout (which is just gamepad mappings);
- I use hybrid layout (mouse to right trackpad and gyro, everything else is gamepad mappings).
Another workaround which kinda works is to plug a gamepad and set it aside. Here are couple of test cases:
- Windows PC, connected Dualshock 4 via cable, set it aside, issue did not occur during 20 minute playtime.
- Windows PC, connected Dualshock 4 via cable, played with KBM config, issue occured.
- Windows PC, connected Dualshock 4 via cable, played with hybrid config, issue did not occur during another 20 minute playtime.
- Steam Deck, connected Dualshock 4 via Bluetooth, set it aside, rearranged gamepads order so DS4 is the 1st, played with SD controller with KBM config, issue did not occur.
- Steam Deck, connected Dualshock 4 via Bluetooth, set it aside, rearranged gamepads order so DS4 is the 2nd, played with SD controller with KBM config, issue occured.
Anyway, if this issue happens to you, and my workarounds don't work, just refund the game. Devs moved on to a different project.
Full play-through, no issues
No issues

With it's last major update back in March, Post Void became a near-perfect game for the Deck's form factor.
A bit of delay when the slowdown occurs, but otherwise - fine
Occasional 2-3 second bursts of slowdown after immediate restarts, and more prolonged slowdown after a while of firing the SMG non-stop while sliding, mostly starting in act two
The only feature I feel this game is still truly missing: Steam Cloud support

Played using Proton 8.0.3 (the current latest one), ran smoothly without any issue.
also such a amazing game!

Texture clipping
Runs very well on experimental. The only issues I encountered were some paintings clipping on the wall and every now and then an enemy appearing on the screen for a milisecond only to dissapear but they're so minor that I don't even notice while playing.

PROTON_USE_WINED3D11=1 %command%
PROTON_USE_WINED3D11=1 %command% in the launch options
Works great out of the box
Works out of the box. No need for tinkering
Works perfectly
Does not work on the River Wayland compositor in a multi-monitor setup
The game launches on the incorrect monitor. The window cannot be tabbed into, all keyboard inputs are dropped and it cannot be moved to the correct monitor.
River is still considered unstable so bugs are to be expected, it works perfectly fine on other Wayland compositors such as Sway.
Works flawlessly out of the box
Works perfectly out of the box.
Game wouldn't launch, regardless of Proton version.
Works perfectly fine
Great Out of Box experience
Played a couple games of Post Void and had no issues, performs as it does on Windows.
Works as well as on windows
Works well out of the box.
PROTON_NO_ESYNC=1 %command%
Experienced random crashes the launch command "PROTON_NO_ESYNC=1 %command%" seems to have fixed it.
