Mouse Clicks not working
I have tried both proton experimental as well as GE. In fullscreen or windowed mode. I cannot fire any weapon or scope with the sniper even though I can click through the menus.

PROTON_USE_WINED3D=1 %command%
Fullscreen on 21:9 monitors are stretched, gamescope don't fix it because mouse inputs just don't work in game.
Some slighty frame drops from time to time because of use on wined3d
For what I see Europe servers are the most filled with players, so if you're in America you will have some lag but I didn't noticed much.
The game needs some fast tweaks before launching, when you launch the game without tinkering you will get the game screen freezed and you can't use the mouse inside the window, forcing the game to wined3d fixes all the issues and it's very playable.

Game works fine except for annoying mouse bug.
Mouse goes invisible randomly which makes navigating UI annoying.
Plays fine.

The game is great for PC players, for steam deck users, not so much, unless you play it with keyboard and mouse
Mouse is frozen on gamemode, needs to be played on desktop mode
The game is incompatible with gamemode, mouse gets stuck on the upper left corner, you can only play it using desktop mode. You also need to connect your keyboard to insert your name when asked, virtual keyboard doesn't work.
Played through the tutorial with no problems
Used proton-GE because Valve marked this game as unsupported, but main issue here is gamemode I guess

Found no issues when I was playing a match

the only proton version that drag me into the region menu was 7.0-6. But even there, the inputs didn't work...
not wotrking on the deck...

Mouse cursor disappeared after the first match, making menus hard to navigate
Crash before launch on regular Proton, needs experimental

runs like native
