The first DX10 (WGF2.0) benchmarks have been released thanks to AMD and Nvidia.
AMD during its R600 launch released an early working demo of the previously released DX9 title, Call of Juarez. The working demo is in reality a soon to be release patch that adds DX10 support and effects. NVIDIA in return "leaked/released" an alpha demo of the DirectX 9/10 game "Lost Planet."
Shown here courtesy of FiringSquad is a preview bench of Call of Juarez running at 1280X1024 with 4XAA. The cards running it are the Nvidia 8800 GTX, AMD Radeon HD 2900 XT and the slightly overclocked EVGA 8800 GTS, whose general performance falls between a stock 8800 GTS and a 8800 GTX.
We have the Lost Planet benchmarks as well courtesy of Beyond3D. Also from Beyond3D we have in depth DirectX 10 benchmarks courtesy of forum member "aeryon". Benchmarks can be found near the bottom of this page.
It seems that finally, seven months after the first DX10 compatible cards launched we have some programs starting to take advantage of their abilities. Shortly in the pipeline we have DirectX 10 patches for Company of Heroes and Supreme Commander, as well as having the DirectX 10 title Crysis and Unreal Tournament 2007 due to be released shortly. This is truly shaping up to be a wonderful era for the graphics industry and the computer gaming industry as well.
