The game won't start with any version of proton, even with vulkan enabled.

Low frame rate (20-40fps) on Radeon RX 5600 XT at medium settings. Only works using the Vulkan version. DX12 doesn't work.
I finished the game without crashes with the default settings

My Steam Deck crashed and rebooted every time I loaded my save, regardless of proton version or graphics options. Tested on game version 1.04.

The game comes with a native vulkan mode by default, which i advise you to enable in order to not lose performances.

Cursor artifacting when returning to main menu.
Lots of stutter and bad performance on Proton 8.0-2 and GE-Proton 8.3. Proton Experimental had stuttering still, but didn't have the performance issues.
When launching the game, launch in VULKAN mode. Otherwise, you will get the error message: "DX12 is not supported on your system. Try running without the -dx12 or -d3d12 command line argument".
Returning to main menu hangs the game. Or it just takes so long I thought it hung.
