My specs are up to snuff, a gtx 780 ti i7-4770K and when I play metro last light for a 20 mins-1 hour it will not only freeze but it will just lock up windows to where I can't do anything even after exiting the game. I exited the game and one time there was a fast notification from nvidia control panel that had some kind of driver error. (it vanished so quick that I couldn't read it in time) Is my graphics card ok? I can run the game on phsyx on everything ultra and get over 100fps. I hope and pray that my 780 ti isn't crapping out on me...
