What's the fastest way to get to a location in the game where this happens?
Anyway, this GPU is GCN 1.0, good chance that there's driver issues happening. Also please attach a Proton log.
This is likely this bug, also with GFX6: https://gitlab.freedesktop.org/mesa/mesa/-/issues/3882
You should be able to workaround this one with RADV_DEBUG=llvm.

The fastest way is to start "End of an Era campaign".
Like MegWATTT mentioned, this could be a RADV ACO compiler bug, when I tried to run with LLVM backend using RADV_DEBUG flag the game simply crashes. Wine gives the following output:
Backtrace:

And also following when using latest DXVK and VKD3D-proton:
This is fixed in latest Mesa3D 25.3.1
