I’m running an i7 (3.4GHz), 8GB of 1333MHz RAM, and a GTX 560ti with 2GB on board. My co worker is using the EXACT same system. He plays with maxxed settings at around 70-80 FPS. I log in (after a fresh computer start) at around 140FPS and then within 2 minutes, I’m down to single digit FPS… with an identical performance drops when I go to min settings.
I’ve updated to the 306.xx drivers for the card. Tried cleaning/reseating the card in either slot I have available. I’ve considered spyware issues and took actions required for that and still suffer from the same problem. I’m thinking it’s my card, but I haven’t gotten a chance to check it out (nor do I have the money for that) yet.
