If I recall, you were running ok on 581.15? Even that version stopped working for you?
I submitted dxdiag and several dump files when 581.15 was current but... since this is an early access game, not sure how much prioritization Nvidia will devote to investigating the issue.

I haven't tried playing in a couple weeks - mostly because we have completed all the available content but also because these stability issues are game breaking.
