I got a Nvidia 8600 GTS, 2 gig o' ram, AMD Dual core 4200+
and i am running it on a mix of Very High (DX10 XP mod) and medium and high. It runs around 19-30 FPS (Which is good for the settings). It was a good surprise to get the editor. i have done alot of fiddling around with Far Cry and other FPS like Half life and Doom so i have a bit of mapping expirence. Crysis so far is the easiest editor.
