Hi, CPU: i5 2500K 8Gb RAM GTX 670 Samsung 256GB HD Performance is not great with the above mentioned card. The settings are all maxed out with 4AA. I have set an aggressive fan profile to prevent the card reaching 70C and down-clocking. It is the reference EVGA model. I experience stuttering at times and slowdown. I can't monitor the GPU as Precision X doesn't work in 64 bit applications. In the past stuttering occurred when my old card was overheating. Some people claim that the game is CPU limited or just badly optimised. I get a 50-60 FPS much of the time but the minute action heats up there is slow down. Anyone else getting similar frame rates or any suggestions how to improve performance? Many thanks.
