I seen some some videos showing a comparison, but honestly I dont really see a big difference. The lighting is different and physics look better, but visualy they dont look that much different from each other.

What do you guys think?

What also sucks is no game even came close to using dx9's full potential graphically, and we all can assume dx10 will never fully be used to its limits also.

If you want a benchmark for dx10 watch all the Crysis videos, and I'm sure more can even be accomplished.
