funny thing is with the rage performance driver, it runs really smooth , but i have these tiles everywhere, on NPC`s, world, guns , vehicles etc etc.
but when i have Battlefield 3 preview driver installed, it doesn't have these artifacts, but then frame-rate is really low, its is kinda playable but more like fast picture slide.

I think the tile artifacts only appear when you check the box for "Disable Catalyst A.I."

I started having glitching weapons issue after I made the initial post too. For some reason, on certain levels, ejected ammo appears and reappears next to my weapon and my weapon sometimes glitches up completely, very similarly to the NPC artifacting. So I guess this is the same issue.
