Absolutely perfect, no issues whatsoever

Great working game, minor issues
Game would crash if I was in fullscreen and moved mouse to second moniter, probably an issue with its custom cursor.
Would crash sometimes when trying to join multiplayer, apears to only be a proton issue.
Works Great!

The game works just like on windows.
The game works just like on windows, although the game felt like it was running at 60 fps even though it was running at 130-144 fps through wayland, but maybe the game just plays like that idk im too lazy to test on windows.

Runs perfectly!
The game runs perfectly without any extra steps.
Works like a charm with 4 player in co-op using different type of controllers

Game started once but wasn't playable, than it didn't start at all
With Proton Experimental game started, but didn't allow me to enter a lobby (it was just infinitly loading) After that (with proton version 6, 7, 8 and Experimental) it didn't start at all and instantly showed one of two Unity errors: "InitializeEngineGraphics failed" and unnamed one.

Really laggy sometimes
It takes a weirdly long time to start (like 20-30 seconds or so!). But after that it works perfectly.
just a second would cut out from time to time on wayland but not on x11
feels like 5 fps
the game's 'tiers of heck' and 'wave survival' are both fine, anything local basically.
after figuring out i had to use an older version of proton it worked great
set max fps to 60

EOS installer was kinda annoying, and I got stuck at the "steam loading" screen. Had to restart the game, and then it worked.
Doesn't launch. Tried also experimental, no launch options and with "PROTON_NO_D3D11=1 %command%"
PROTON_NO_D3D11=1 %command%
Gives a Windows style error message after installing epic games libraries I assume: "Failed to initialize graphics. Make sure you have DirectX 11 installed, have up to date drivers for your graphics card and have not disabled 3D acceleration in display settings. InitializeEngineGraphics failed"

5000 Ping. Extreme Delay

Good game. Tons of fun and works well on linux with no tinkering needed.
Most of the issues I assume were because of the netcode itself and not necessarely proton interfering.

Multiplayer works perfectly.
Works perfectly, no linux specific issues.

Proton versions tested: 7.0-1, Experimental. (Could only test demo, so that's probably why ProtonDB thinks I don't own it)

Game runs perfectly out of the box.
Multiplayer wasn't thoroughly tested but from what I could tell it worked fine.
