Game may slow down when switching between programs (ALT+TAB)

Very low frame rate in places, especially at the end of the game. Couldn't select menu items sometimes.
After the 3rd time launching the game I couldn't select the menu items unless I went way off the side of the screen away from from the menu items.
Huge frame rate drops in place and could rarely keep it at 30fps

Low settings and limited to 30 FPS
Below 20 FPS in many areas and when multiple enemies were on screen
Its playable if you can deal with low FPS at times
There are minor drops in the FPS value when loading a location.
Both versions of Dx11 and Dx12 work acceptably.

Industria (DX12) version 1.3.2 works flawlessly using Proton 9.0 (Beta). Performance is great.

Playable, but with annoyances
Sometimes, light shines through walls and water puddles are always bright, even in the dark
Resolution can't be changed in fullscreen mode. Workaround: Switch to windowed, set your resolution and then switch back to fullscreen. Game sometimes starts in a small window with only a small fraction of the menu visible. Pressing Alt+Enter twice maximizes the game properly
Occasionally, performance suddenly gets extremely slow. This is mostly caused by making some graphics settings changes, advancing to the next map or having died. Restarting the game brings performance back to normal.
Some graphics settings, e.g. anti-aliasing or shadow quality, always get reverted when restarting the game
Fully played through the DX12-version.
Worked perfectly

Significant Performance problems and is slightly unplayable given quick time events, and shooting mechanics . It can be done, however its really hard to manage
With the underlining performance issues, it makes the game much more complicated, and takes away the fun out of playing, would recommend playing on a different device.

game will load into the main menu, but cannot interact with the menu at all, making the game unplayable ⚠️

Use DX11. Has some issues with frame-rate dips because its Unreal 4 (even with reduced settings), but ran well otherwise.
Works out of the box
Finished the game without having any issues.
Finished game without issues
Works very well
probably just optimisation but i wasnt able to maintain a stable framerate unless i turned off all raytracing. max settings and resolution otherwise maintained a solid 60-80
ran perfectly
i think most pf the problems here have nothing to do with running it on Linux, it is just the game itself.
glowing objects, texture artifacts, various glitches
Performance is all over the place, frametimes are okay-ish
crashes in the first plaza until i switched to DX11
once crashed
Proton 6.16-GE-1
The default DX12 mode has sosme problems, so you better use the DX11 mode

I had to use the DirectX 11 launch option or the game would crash after 10 seconds.
Works perfectly as if it were running on win natively :)

The Steam Nextfest demo works out of the box but the performance isn't great. I finished the demo without any other issues.
The game is not finished so the performance of the final product might be better

I could play through the full demo (40min) without any problems.
Switching to fullscreen caused several crashes. After retrying some times, fullscreen worked perfectly and stayed enabled.

Game started windowed, but the cursor icon was not aligned with where the cursor actually was. Fixed by pressing Alt+Enter.
Game crashed twice: during fiddling with graphical settings and during the first 5 minutes of gameplay.
