My crashes seem totally random.
One day I play over-clocked to 1500 on the 970, no crashes at all, all day.
Next day, 5 crashes on same settings - reduce over-clock & run windowed with frame-rate limiter (no crashes).
Next day, same settings as the previous - 4 crashes....
I'm starting to think it's just random...., the drivers have made little difference overall - had the same black screen or random inventory screen pauses regardless of the patch version.
I even tried K-boost on the EVGA booster utility to see if it was graphics card power scaling causing the issue (when switching between inventory & game) - had a driver failure that time...
So far I've identified four key crashes.
Inventory lock-up.
Instant to desktop crash.
Black screen, visuals die - can still hear sound.
Black screen, back to desktop - then 'display driver has crashed'
Thankfully on average it's one every 2 or 3 hours, so not game-breaking. The annoying part is I like to play on my sofa on my projector with a game-pad & nothing is more irritating than having to get up every time something goes amiss during a key scene!.
Infinity easier to play with a controller. I couldn't kill a damned thing until I stuck my Xbox One controller in. Adventure RPG games are always better with a controller IMO.
Indeed, using a PS4 controller & dodging/rolling is significantly more accurate & easier.
On the hardest difficulty I have trouble saying alive on the keyboard, but with the game-pad it's pretty easy.
