OS: Vista 32bit Sp2 CPU: Intel Core 2 Quad q9559 OCd @ 3,6 GHz Ram: 4 gigs GPU: 2 Sapphire HD 4870 in Crossfire OCd MB: Asus P5Q-E Res: 1920x1200 Settings: AAx4; AFx8; no Bloom; Details at max Game runs at 60 fps in most indoor areas, but drops half in outdoors (most notably in The Outpost;even with no AA). I get the crazy sky-box issue, which strangely goes away when looking at the stars from underwater. Otherwise it runs fine.
