The upcoming STALKER: Call of Pripyat is one of the few games that will support the new DirectX 11 API, and developer GSC Gameworld has already revealed a few screenshots comparing the two. While you can’t see much difference, as it’s still early and the first few games don’t utilize the new software the best way, there’s still noticeable improvements.

In the screenshot above, the left side is DX 10.1 while the right is DX 11. Notice the gas mask and how the air filter is properly round instead of angular. FiringSquad has a lot more screenshots here.
