I was getting this too. Setting a tdrdelay in the registry fixed it for me.
Nope, none. Every game runs noticeably better than with my 980Ti @3440x1440. Only game causing me issues is Mass Effect Andromeda... at max everything, it crashes with a DX low memory error. I doubt its the card.
EDIT:- letting windows control my pagefile seems to have fixed the issue. I didn't think a pagefile would be an issue on an 1TB SDD with tonnes of space.
Anyway - game running at max EVERYTHING, 3440x1440... I cannot believe i'm getting 60+ fps constantly (cutscenes don't count )
What a BEAST of a card! Well worth the 8 weeks of pre-order!
