Week number 2, and a hotfix later, still 'Fatal Direct X11 error.'

As I told heres my Update. it seems underclocking my GPU did the trick for good, had no crashes since then.

Same here, kind of.

Since im using a 3080 that tends to rapidly switch voltage or clock extremely high all of a sudden i set -175mhz in MSI Afterburner for one.
That already reduced the crashes.

However what really seemed to fix it in the end (formerly, 1 crash every other hour - now, 1 crash in a week or two) was to limit the FPS via Nvdia Control Center to 119. That did the job for me for now.

Apparently the stable 144 i was running before werent quite manageable by the engine - only a guess.
