After the last update it has become impossible for me to run the game smoothly. The framerate is very jittery and jerky, and it doesnt matter whether I set graphics up to ultra or down to low. Previously I could avoid the problem by setting the process priority to high and cpu affinity to only the first 2 cpu-s, but that doesnt seem to help much anymore. Im running it on win7 SP1 32bit. NVIDIA Gtx 660 and i5 CPU 2,8 Ghz is enough to run most other games on high at least, but this doesnt even run on low atm.
