1. best driver for Nvidia 6xxx cards is 78.01 (for performence) and for 7xxx cards 78.02 (for performence with a little better image quality)properbly you use no SLI because the new drivers fixes some probs to this.
2.if you got a slow cpu reduce shadows(better turn off) and the smooth smoke.
if you got a slow g.card reduce texture quality and AA/AF.
3.iam a german dude so dont pls laugh if you find some "unrights"
