Here's my specs.
XFX 7800GT 256mg 473/1150 (91.73 Tweaks R Us)
2gigs Gskill@ddr520 3-4-4-8-12
3200 Venice@2.6, socket 939
Defragged, Prime stable, good drivers, play AA, UT2k4 mods, Joint Ops maxed, GRAW medium details, all at 1440x900. Tried this demo that was recommended by a friend, and all I can say is, call me in 2011 when we're all playing on 4ghz octagon cores and 1 ghz/1gig GPUs. The engine in this demo is GARBAGE and good luck porting it to the USA where most people have a 6600 card and a P4 and a gig or less of ram. This game has serious potential yes, and I would love to play it, coop loocks great, but...
I would rather hit myself in the head with a hammer repeatedly then play any game at 22 fps with no AA AF or details at 1024x768, for my brains on the carpet would look much prettier.
