Runs pretty poorly by default. Drop VRS to Performance, Dynamic Resolution to a target framerate of 30fps, and TSR to low. Maintains 30fps.
Forced GE Proton 9-13 required to bypass an error at launch.
Just use latest GE-Proton9-13. Works out of the box
Occasional dips to 10 FPS
Switching to Proton Experimental bleeding-edge beta resolved the launch errors. Gameplay is pretty stable at 30 fps using lowest graphic preset
Was able to play multiple chapters with no issues aside from getting less frames compared to windows.
Performance is slightly worse compared to windows
Could only get game to run under newest Ge-Proton9-13
Game does not work with the current default Proton. But it is playable with Proton Experimental Bleeding Edge or GE Proton 9-13.
To use Bleeding Edge of Proton Experimental, search for "proton experimental" in your Steam Library > Right Click and select Properties > Beta Tab > Select "Bleeding Edge - Latest and untested".
Note I used an older Linux Kernel because I experience some random crashes with the 6.10.x kernels. Also I used Mesa git because there is a couple of minor graphical glitches with the current stable. It is most noticeable on Chris alternative outfit once you unlocked it.

Forced Bleeding Edge Proton Experimental
Worls witch Proton Experimental and the Bleeding Edge Beta
Game does not natively support Cloud saves, must transfer save manually.
Performance is slightly worse than windows
Didn't test for very long, didn't play through the whole game under linux.
Proton 9.13 fixed "!status && "vkCreateComputerPipelines" error and allow me to play the game
Game is working with GE-Proton9-13
gamemoderun gamescope -feh 1440 -- mangohud %command%
Crash After Into Cinematic
Some kind of Assertion error. This is on the Demo.
Fails with a Wine error
gamemoderun gamescope -feh 1440 -- %command%
Tried Hotfix too, no dice.
Doesn't start, stays at "Launching"
Tried demo and crashed after the opening cinematic
Assertion failed - "!status && "vkCreateComputerPipelines"
When the auto-save notification comes up, the game crashes due to an Assertion failure.
"Expression: "!status && "vkCreateComputerPipelines"" - Also tried Proton Experimental but did not work.
Doesn't work after intro FMVs
Error:
Wine C++ Runtime Library Assertion failed! Program: CastingFrankStone.exe File: ./dlls/winevulkan/loader_thunks.c Line: 2738
Expression: "!status && "vkCreateComputePipelines""
Press OK to exit the program, or Cancel to start the Wine debugger.
There's an issue after goes to the menu
Tried with Proton Experimental and ProtonGE 9.11. Probably will be fixed by Valve after launch.
Pre-release game demo. Fails to start with error: Assertion Failed. Expression: "!status && "vkCreateComputerPipelines""
Maybe some tricks to start this game will be found later. Only tried pre-release demo so far
