I can't get my copy of NFS prostreet to work properly with my rig. If I set everything on lowest with 1280x1024 it'll run at around 18 fps, with everything highest it runs around 15 fps. It doesn't make any sense to me. I have all the latest drivers and directx. My friend runs it perfectly on his laptop which has a geforce go 7900gs, which is a good deal slower than my card. Does this game have issues with ati card or something?
