Lowest settings dips below 30fps for me even with V-Sync off. This is unacceptable. The beta ran much smoother. Using 310.90 driver at the moment as it runs better than 314.07 (NVIDIA failing there). Please Crytek, can you let us know if you are fixing the performance issues in the single player game in the inevitable patch?
My PC:
Intel Core i5-3210M 6GB DDR3 1600 NVIDIA GT 650M 2GB Crucial M4 SSD 256GB Windows 8 64bit Pro
I think performance issues are prevalent all around the Crytek PC consumer base. I'm running on two crossfired 2GB 6950s, an i5, and 12 GB of RAM, yet the FPS ranges from 60FPS to 7FPS.
