When trying to play ARK with high level graphics options, GPU fails to recover on reset, setting GART to 2048 or 8192 results in same fault. If I keep graphics - textures - to high vs ultimate, the game works.

I've attached various logs from the fault.

Disabled some kernel options, close this and reopen specific for AMD only.
