Linux Mint with Proton Failing to Boot

[RoaminGrape]

I've tried a variety of different ways to boot this mod. With and without the bat file- with its launch arguments in the base game, every time it would load to cache resources, the loading screen reaches %100, and the screen would quickly flash and hang on loading. It drops an error that read along the lines of cl_thirdperson command unknown. Every boot after just quick loads with no effort to load in the assets or shaders. It will load the remix menu, but that's all.

Update: So I was able to get the game to skip making the assets from the mastercache, but it behaves like it did before with the full-bright and no attempt of remix creating new shaders.

Did you find a way to play this game? If not I can say that today I found how to play it with PT effects:

1. Download v1.4.7900.25 and extract only dxwrapper.asi to bin folder, dxwrapper.dll can be deleted. Check that dxwrapper.ini contain this string LoadCustomDllPath = .\p2-rtx.dll, or put p2-rtx.dll to the bin folder and set LoadCustomDllPath = p2-rtx.dll.
2. Put this options in steam launch options: -windowed -insecure -steam -novid -disable_d3d9_hacks -limitvsconst -softparticlesdefaultoff -disallowhwmorph -no_compressed_verts +mat_phong 1 . Game can work w/o -nogamepadui like Run on linux? #159 (comment) mentioned.
3. Only proton 10 beta and experimental provide PT effects, vertion 9 not work.

For me I tried using proton 10 (I think?) and Portal 2 does open the remix menu even loads, but the rtx effect doesn't apply?

It's possible if combining RTX Remix outside of this repository with a newer or older from other repositories (https://github.com/NVIDIAGameWorks for example). That worked for Portal Prelude RTX, where possible to update outdated remix with a newer one with much better performance, but this trick not working for Portal 2. Only upscaling, ray reconstruction dlls like nvngx_dlss and nvngx_dlssd can be replaced.
