Fix SwapChain11 backbuffer depth stencil issues on FL9_3 #856

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
We seem to have problems with supporting Depth Textures on Windows 7. They seem 
to work okay on Windows 8, but currently in SwapChain11 we get a failure:

D3D11 ERROR: ID3D11Device::CreateTexture2D: Device does not support the format 
R24G8_TYPELESS. [ STATE_CREATION ERROR #92: CREATETEXTURE2D_UNSUPPORTEDFORMAT]

Assigning to you, Austin.

Ah, yes. D3D10Level9 didn't support *_TYPELESS formats in Windows 7. Limited 
support for this was added in Windows 8.

We've hit similar issues on some Win8 drivers before, so we already have a fix 
for this in our branch. I'll port the fix over today.

Great! The other issue was the availability of the depth stencil SRV, and using 
it as a shader resources. I guess 9_3 doesn't have depth textures, at least on 
Windows 7. Thank you Austin.
