If you are not out a Quakeconn and need something to take care of your DX11 fix then the following video from PCPerspective should do quite nicely.
The demo shows of Dirt-2 complete with D11 engine and running on ATi Radeon DX11 hardware. The effects are very impressive as the trailer shows actual in-game footage.
DX11 will debut with Windows 7 in October, this is when we should see DX11 cards from ATi and possibly the first reviews of nVidia DX11 parts. Availability of these should be around the holiday shopping season if the information we have is correct.
Enjoy the video but you might want to turn your speakers down as the volume is lound.
