My fps was worst centered around the following image at lowest detail setting. I would get 22 fps while the camera was stationary & minimap open. 24 fps while the minimap was closed. At highest video settings (at 0 anti-aliasing though), I was getting 17 fps at this same image with minimap open, 19 while closed.

Also I noticed, at highest video settings with the minimap zoom level set to 300 (had to be 300), I would get these strange lines across the minimap.
