There are a number of easily available replacements. All versions of D3DX are deprecated as is the legacy DirectX SDK itself (see MSDN). In fact, you should be using DirectX Tool Kit instead of the legacy D3DX11 library. PContext->CopyResource( pStaging.Get(), pSource ) Otherwise, create a staging texture from the non-MSAA source Handle case where the source is already a staging texture we can use directly PContext->CopyResource( pStaging.Get(), pTemp.Get() ) Įlse if ( (desc.Usage = D3D11_USAGE_STAGING) & (desc.CPUAccessFlags & D3D11_CPU_ACCESS_READ) )

Hr = d3dDevice->CreateTexture2D( &desc, 0, pStaging.GetAddressOf() ) If ( !(support & D3D11_FORMAT_SUPPORT_MULTISAMPLE_RESOLVE) )įor( UINT item = 0 item ResolveSubresource( pTemp.Get(), index, pSource, index, fmt ) ĭesc.MiscFlags &= D3D11_RESOURCE_MISC_TEXTURECUBE ĭesc.CPUAccessFlags = D3D11_CPU_ACCESS_READ Hr = d3dDevice->CheckFormatSupport( fmt, &support ) Hr = d3dDevice->CreateTexture2D( &desc, 0, pTemp.GetAddressOf() ) ĭXGI_FORMAT fmt = EnsureNotTypeless( desc.Format ) MSAA content must be resolved before being copied to a staging texture

PContext->GetDevice( d3dDevice.GetAddressOf() ) HRESULT hr = pSource->QueryInterface( _uuidof(ID3D11Texture2D), reinterpret_cast( pTexture.GetAddressOf() ) ) Return HRESULT_FROM_WIN32( ERROR_NOT_SUPPORTED ) If ( resType != D3D11_RESOURCE_DIMENSION_TEXTURE2D ) Here's the code in the ScreenGrab module in DirectX Tool Kit that does this handling: static HRESULT CaptureTexture( _In_ ID3D11DeviceContext* pContext,ĭ3D11_RESOURCE_DIMENSION resType = D3D11_RESOURCE_DIMENSION_UNKNOWN

In turn since ResolveSubresource returns a void, you need to check the format supports D3D11_FORMAT_SUPPORT_MULTISAMPLE_RESOLVE before using it. You have to explicitly use ResolveSubresource before doing the copy. In particular, if your swap chain buffer is a MSAA resource this will fail to get any data. Instead you need to enable the Direct3D DEBUG device and look for any ERROR or WARNING messages. One possible point of failure is CopyResource which returns void so you can't detect the problem in your code. HRESULT hr = d3d11Device->CreateTexture2D( &description, NULL, &pNewTexture ) First, you need to be explicitly checking the return code for all functions that returned HRESULTs HRESULT hr = SwapChain->GetBuffer( 0, _uuidof( ID3D11Texture2D ),
