The release of Direct3D 10 exclusively for Windows Vista was an unpopular move. Windows XP gamers felt that this was a move by Microsoft to make them switch to Windows Vista so that they would be able to enjoy the benefits of the new technology. This meant that someone playing a game like Crysis on Windows XP with a DirectX10 compatible video card would be only able to run it in DirectX 9 while a gamer playing it on Windows Vista would be able to make use of DirectX10.
Gamers with a DirectX 9 compatible video card would on the other hand also only be able to play the game in DirectX9. This is something that Microsoft intents to change in Windows 7. Microsoft will – according to Long – make use of something they call Direct3D 10Level9 which will allow users to run Direct3D 10 applications on Direct3D 9 hardware. This has an impact on the performance obviously.
Windows Advanced Rasterization Platform (WARP) will kick in if the video card is not supporting Direct3D 9 or Direct3D 10. Direct3D 10 can then be fully emulated by software. The image quality will be almost identical to that of Direct3D capable hardware. The downside is a huge performance drop that will make games like Crysis unplayable on even the fastest processors.
The fastest tested processor (Intel Core i7 8 Core @ 3.0 Ghz) managed an average of 7.36 frames per second in the Crysis benchmark running at 800×600 with lowest settings. That’s more than the Intel DirectX 10 integrated video card managed but only a tenth of a NVIDIA 8800 GTS video card.
