Hello, I've got the same issue; I will try reinstalling the older drivers-although, is there any chance this will be fixed to support the latest drivers perhaps? As playing with the flashing cursor also makes the game freeze. If I'm moving my cursor around, it literally makes the game freeze if I do it fast enough. It starts after about an hour of being in-game, at least in my case. I just like to keep all of my things up to date, so this is slightly annoying, although I have seen another service I use crash and mentioning the Nvidia drivers... So perhaps it is possibly their fault, not yours?
