I see certain buildings and pieces of walls in the distance (not necessarily very far away) flickering sometimes and then stopping to do so when I move. It's minor, but it detracts from immersion. I have a pretty strong computer i7-3.4 Ghz with a Radeon 7700 2Gigs and the frame rate is great. Turning down to medium doesn't really help with flickering. I'm thinking there's a graphical option somewhere in "performance" that my graphics card has trouble handling properly for some reason. Any idea what that might be? Is it just the Serious engine's fault doing that to everyone and I should learn to live with it?
