they both are a work in progress. i still think that previews of dx10 performance look a little depressing. my friends 8800gtx can barely handle the new lost planet dx10 demo. im not really sure if its really dx10 but the point is at 1900x1400 or some res like that it can barely handle 30+ avg fps. then again the game looks like it was brought straight over from xbox 360 with no computer coding in mind.
