   Dx11 on Geforce 6600
  I'm using DirectX 11 with 9.3 hardware level for my geforce 6600;The problem is that I cant create tthe depth buffer. I've tryed almost all the formats but no luck.Any idea ?   D3D11_TEXTURE2D_DESC depthBufferDesc;depthBufferDesc.Width = 640;depthBufferDesc.Height = 480;depthBufferDesc.MipLevels = 1;depthBufferDesc.ArraySize = 1;depthBufferDesc.Format =  DXGI_FORMAT_B8G8R8A8_UNORM;depthBufferDesc.SampleDesc.Count = 1;depthBufferDesc.SampleDesc.Quality = 0;depthBufferDesc.Usage = D3D11_USAGE_DEFAULT;depthBufferDesc.BindFlags = D3D11_BIND_DEPTH_STENCIL;depthBufferDesc.CPUAccessFlags = 0;depthBufferDesc.MiscFlags = 0;if(FAILED(pD3DDevice->CreateTexture2D(&depthBufferDesc, NULL, &pDepthStencil ))){MessageBox(hwnd,"Failed to Create Depth Texture","",MB_ICONERROR);return;}I get the "Failed to Create Depth Texture";PS: Works on a Dx10 compatible video card (radeon HD 3650).   
  Why are you trying to create a depth buffer with color components and no depth components? Where is the depth information going to be stored?   ;  Does the Geforce 6600 even support DirectX 11?  I thought only the latest cards from ATi (5xxx series) and NVidia (4xx series) supported DirectX 11.   ;Quote:Original post by MoeDoes the Geforce 6600 even support DirectX 11?  I thought only the latest cards from ATi (5xxx series) and NVidia (4xx series) supported DirectX 11.Direct3D 11 runs on downlevel hardware. In his post he mentions that he's using the 9.3 feature level.   ;  As Mike hinted in his first reply, you should use a different format for the depth buffer. Try replacing it with one of the following:// Without stencil bufferdepthBufferDesc.Format = DXGI_FORMAT_D16_UNORM;depthBufferDesc.Format = DXGI_FORMAT_D32_FLOAT;// With stencil bufferdepthBufferDesc.Format = DXGI_FORMAT_D24_UNORM_S8_UINT;depthBufferDesc.Format = DXGI_FORMAT_D32_FLOAT_S8X24_UINT;;Quote:Original post by Mike.PopoloskiQuote:Original post by MoeDoes the Geforce 6600 even support DirectX 11?
