I just brought an Radeon HD 6670 for coding HD3D tech。I have updated the video driver, It doesn't work.
I'm working on Windows7 64bit with DirectX SDK(June 2010) and last Catalyst.
It failed on：
//Create a surface to be used to communicate with the driver
hr = pd3dDevice->CreateOffscreenPlainSurface(10, 10, (D3DFORMAT)FOURCC_AQBS, D3DPOOL_DEFAULT, &pDriverComSurface, NULL);
D3D Debug Info:
Direct3D9: (ERROR) :This format is not supported for offscreen plain surfaces. CreateOffscreenPlainSurface fails.
D3D9 Helper: IDirect3DDevice9::CreateOffscreenPlainSurface failed: D3DERR_INVALIDCALL
