I've got the drivers from GeForce Experience.
For getting the TDR failure, thus far it has been a one-off. It happened whilst playing the game, I think quite a few special effects were happening at the time - but I was playing for a good hour or two. If it happens again, I'll post again. I might have just been unlucky. I've not been able to reproduce it since. But then I am ATM playing in 1080p instead of 1440p because I get 60fps in 1080p and not in 1440p, I'll do a session of running at Max settings at 1440p to see if it replicates.
