On a i5-3210M, 8GB of DDR3 RAM, 2x NVidia GT 650M (SLI) machine with almost every graphics option set on maximum I had no problems, no FPS drops, it was running on my pre-set limit (83,3) all the time. Gonna test it on a much weaker machine today, it's a Core 2 Duo E4300 with an AMD 6450 1GB. I will report my experience here.
