Hi Lar_q,
some people have problems to get Anti Aliasing to work. Is it possible that you give us a little advice what drivers and settings we should use for ATI and NVidia? Probably the same you've used in your test-machines. Or is this problem also solved in the next patch?
I also have problems with SLI. All Settings i've tried are resulting in graphic errors. (and i've tried many settings, especially oriented on fallout 3 and oblivion-profiles)
Thats my pc:
Core i7 920@3ghz
Nvidia Geforce GTX 295(Driver 190.38)
6GB Ram
SB X-FI
Vista 64
