Since the last major game update, my performance has encountered a lot of stuttering. Around this same time as the update, I added liquid cooling to further overclock my processor. I also added a second Nvidia 560 Ti to my setup and enabled SLI. note: max temperature for this CPU is about 80 degrees C hardware prior to this issue i7 920 at 3.4 GHz *temps of 60-70 degrees C on air cooling 3 GB DDR3 RAM at 1600 MHz 560 Ti Superclocked with latest Nvidia drivers (non-beta) as of the days before the update graphics settings Nvidia Control Panel: application preferences PS2: high with no motion blur current hardware i7 920 at 4 GHz *temps of 60-70 degrees C on liquid cooling 3 GB DDR2 RAM at 1600 MHz 2 x 560 Ti cards with latest Nvidia drivers (non-beta) as of this post graphics settings Nvidia Control Panel: application preferences PS2: high with no motion blur Here is a video showing my issue.
