If it says that doesent it mean
Direct x 11 can run on directx 10 HW?
Oh well, We will see when some dx11 games come out.
1. it states DX10 can run on DX11 hardware. Read it below
"The next version of DirectX (DX11) will fully support Windows Vista (DX10) as well as upcoming versions of Microsoft’s operating system (Windows 7), as well as all graphics cards designed for DirectX 10 and 10.1, the company revealed during its GamesFest event in Redmond."
so new DX11 card will support (aka be able to run) DX 10 games as well as DX11 games.
2. DX11 games are out, you cant run DX11 on DX10 cards, its not even an option in the menu.
3. that article is two years old
