Is Company of Heroes the first game that supports Vista’s DirectX 10 ? It looks nice from the few screenshot over at the gamereplays forum, but not that much spectacular from DX9. So dont rush out yet to get that Nvidia 8800 card, unless you got too much money burning in your pockets ;).
Great post on the Channel9 Coffee House board about the upcoming Windows Vista OS:
Vista and Longhorn Server Features for Developers.
Looks very promising to me !
