Forza 4 crashing

Looks like AMD guys can already play Forza 4 via new proton.
For me, gaming is crashing after few minutes of gameplay.
I tried drivers: 470.86 & 495.44.
If cache is not compiled, it is crashing right after splash screen.

Proton issues:

I bought the game last weekend and played for few hours with no issue and pretty neat performance even with graphics settings maxed out. I’ve got 3060Ti, Arch Linux, 5.15 kernel, 495.44 driver.

AFAiK there are some issues with the online mode, but I haven’t tried that just yet.

So this looking more as architecture issue (pascal / gtx 1070, linux 5.15.5)

I seem to be affected by this as well on an RTX 3070
