Ran into this issue as well with Starship Simulator Demo and driver 535.54.03
NVRM: GPU at PCI:0000:26:00: GPU-6f98b267-20cc-5347-51dc-8bad07fd2ad0
NVRM: Xid (PCI:0000:26:00): 31, pid=1000, name=GameThread, Ch 0000006e, intr 00000000. MMU Fault: ENGINE HOST0 HUBCLIENT_ESC faulted @ 0x0_19d00000. Fault is of type FAULT_PTE ACCESS_TYPE_VIRT_READ
Hopes where high it was also fixed by this issue which seems to be solved now, but the above error is still there using VKD3D in version 2.8.
With Proton Experimental using VKD3D 2.9 this issue seems to be circumvented by the compatibility layer as the game ran stable for several hours straight.
I recommend re-testing your games with VKD3D 2.9 and see if the issue is also solved this way.
Maybe it’s not a driver bug but an application error doing something illegal.
