I'm getting huge fps drops whenever I enable the minimap, most notably in the grid or places like inferno missions (due to the crowd?), according to the builtin fps counter I drop from 100 to 5 fps in the grid whenever I open the minimap.
Is this a known issue/is there any workaround?
Edit: Upgrading to windows 7 and installing new newest ati drivers (that wouldn't install on xp for some reason) seemed to fix this :)
