I have a good system, Qx9770@3.6 and 2x GTX 295 in non-sli. Latest Drivers, and I am using the .dll fix. I get this stuttering in general, it is really noticeable when I turn around really quickly. Can someone help me with this problem?
That's the "other" major performance glitch, and it can be solved for most people by turning down Water Multisampling from the advanced options in the launcher. If that doesn't help, try turning down reflection quality as well. It probably sounds like a long shot, but this one's actually made it onto the official support page if you look around there a bit.
