Doesn't work on my machine.

The game throws an error message about a falsely identified video card then freezes at the Crytek splash screen.
Here's part of the log:

@pszabo75 Wait a second, your saying you have an MX150 but your machine spec auto detect says you have a GTX 470? Might that be your issue?

I'm really not sure how to go about fixing it if it is, but that's very possibly the problem.

@pszabo75 Just to clarify, is that a notebook, and if it is, what brand and model?

This is a notebook. A Lenovo T480 with Geforce MX150. I have the proprietary Nvidia driver installed. The Nvidia control panel identifies the GPU correctly.
Native Linux games installed from Steam identify the GPU correctly.
And yes, according to the logs and the error message that pops up after launching Crysis 2, it seems to be identifying it as a GTX470.

Game works almost fine(except random fps drops which may caused by ntfs driver or maybe not).

At least there is one bug - gamma can't be changed. On windows this option change the whole system gamma/brightness.

EDIT again: After being linked to #813 to resolve driver issues, everything seems to work just fine. Just user error for me.

EDIT: Indeed I am an illiterate idiot! I used the more correct PROTON_USE_WINED3D11=1 and Crysis 2 rendered everything correctly. Since using OpenGL d3d11 over DXVK d3d11 worked, I'm unsure if the problem is in the vulkan mesa driver, dxvk, or simply the muxless switchable graphics setup. I did have to launch steam with "env DRI_PRIME=1" for the amd card to work.
Performance was decent albeit lower than my hopes, but the game felt sluggish in a non-framerate related way I have a tough time describing.
On the other hand using PROTON_NO_D3D11=1 to force dx9 made the performance flawless, even on Ultra settings (1920x1080)!

OLD POST:
Only partially works for me.
-Cutscenes appear as pure magenta/pink.
-Font/Text does not render correctly they appear as rectangles with size varying appropriately by letter.

The rest of any scene appears to render correctly though performance is questionable. As font does not work I cannot determine my settings, I struggled to navigate the menu to start a new game even.
I didn't play far enough for combat so there may be more problems, but that didn't appear to be the case.

I attempted to use "Set Launch Options" for wined3d11 and nod3d11 and results did not change. Either I did it wrong (far from impossible) using wined3d11=1 %command%, or crysis defaulted to dx9 for me to begin with.
Using DRI_PRIME=1 crysis determined the 8970m was a Radeon HD 7800, which I don't believe to be a bug as I also believe the 7970m,8970m are just desktop 7800s or at least very close. I know this because it gives me the same unsupported card error I believe pszabo75 is receiving.

I can't activate "High Res Textures" under "Advanced Graphics Options".

I'm running Proton 6.3-5 and a Nvidia GPU.

There is an open bug at winehq
Seems to be related to the GPU memory reported to the game.
I tried setting in dxvk.conf:
dxgi.maxDeviceMemory = 1536
dxgi.maxSharedMemory = 1536
but this doesn't work.

I have the suspicion that the above setting is DX11 only, but we need this for DX9(error message at game startup displays the d3d9.customDeviceDesc setting), however this setting does not exist for D9VK, it seems?!?

There is still no way to get the game to use the high res textures, the option is still greyed out and no amount of dxvk config settings seems to fix it. The HD texture mods also do not work

EDIT: The games log reads GPU Vram as 0

This issue has been fixed for me, 'high res textures' can be turned on and off.
Video memory is reported as 3GB on my 7900XTX.

I'm running 'Proton Experimental', what's your proton version?

Running Proton Experimental Bleeding Edge :\

EDIT: Its possible that because im running a laptop its somehow refusing to see my dGPUs Vram

EDIT2: YUP! that was it, i figured since it was giving me the proper vendor and device id for my dGPU things are fine but by forcing my dGPU as primary that fixed it....as they say about assuming

I switched around proton versions and found that this was fixed with Proton 7.0-6.
Maybe somebody with Nvidia hardware can verify, so this game can finally be whitelisted?

Looks good. High res textures available. But I got same problem as it was in 2018 - in-game brightness cannot be changed
