Just wanted to update and throw my 2 cents in...
Last night I downloaded the DX10 Demo and maxed out all setting and was kind of happy till I noticed that my AA was only at 4x. I was receiving 25-70fps...Then started playing with my settings and saw such a performance drop and was bummed out. So what did I do you ask? Well I traded my 2SLI 320 GTS' and got me one of the 8800GTX KO ACS3 today and all I can say is DAMN What a card. With this card, the game ran insane. Maxed out settings with 8xAA and was getting anywhere between 35-80fps (depending on scene) When I went indoors frame rate was amazing. I am very impressed with the graphics DX10 has to offer in this early stage and can't wait for more.
I tried to use fraps with this game but does not work anybody else got suggestions...
