Non je parlais de Halo 2 Vista, je l´ai lu dans un FAQ de Bungie
Why will Halo 2 for Windows Vista not support DX10?
Halo 2 will certainly support DX10 graphics cards but the game itself is not being re-written to specifcally take advantage of upcoming DX10 features. The more robust your graphics card, the more visual features and fidelity you will be able to enjoy.
