On my GTX 670 WDDM 1.3 and tiled resources seem to be supported. However I can't get the tiled resource sample (http://code.msdn.microsoft.com/Direct3D-Tiled-Resources-80ee7a6e) to work.
I already posted the following in the Q&A section of the sample page:
I have a Nvidia GTX 670 and use the latest 326.01 driver. DirectX says that TIER1 resource tiling is supported.
When I execute the sample the first error occurs at TerrainRenderer.cpp:102
// Create a wrapping trilinear sampler with max-filter behavior.
samplerDesc.Filter = D3D11_FILTER_MAXIMUM_MIN_MAG_MIP_LINEAR;
If I comment out "samplerDesc.Filter = D3D11_FILTER_MAXIMUM_MIN_MAG_MIP_LINEAR;" then the error doesn't occur.
The second problem occurs in ResidencyManager.cpp:700
All entries in the resource->subresourceTilings array have WidthInTiles = HeightInTiles = DepthInTiles = 0. Therefore subsequent calls that allocate textures fail because of a size of 0 (WidthInTiles * HeightInTiles == 0).
Can anybody help me?
Has anybody fixed this or is it a driver problem?
