Valve To Support DX10 With Episode 2
In an interview with Game Informer from last week, representatives from Valve confirmed that they'll be supporting DirectX 10 functionality in the release of Half-Life 2: Episode 2 and Team Fortress 2. This will be the case even for those folks who haven't upgraded to Vista yet. No worries if you don't have a DX10 card, though. They've got functionality nailed all the way back to DirectX 8, and are trying to push it all the way back to 7.
Arnt those platforms that have Dx7 no longer supported by Microsoft?
