DXGI ERROR: IDXGIFactory::CreateSwapChain: Flip model swapchains (DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL and DXGI_SWAP_EFFECT_FLIP_DISCARD) do not support multisampling. DXGI_SWAP_CHAIN_DESC{ SwapChainType =

• 以上是D3D12 調用CreateSwapChain失敗后的報錯信息，大概意思是，不支持多重采樣功能，
• 這里感覺很奇怪，我使用的是最新的顯卡驅動，最新的Direct SDK，還會不支持多重采樣，具體原因待查
• 以下是我的報錯的代碼：

mSwapChainDesc.BufferDesc.Width = 1366; mSwapChainDesc.BufferDesc.Height = 768; mSwapChainDesc.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM; mSwapChainDesc.BufferDesc.RefreshRate.Numerator = 60; mSwapChainDesc.BufferDesc.RefreshRate.Denominator = 1; mSwapChainDesc.BufferDesc.ScanlineOrdering = DXGI_MODE_SCANLINE_ORDER::DXGI_MODE_SCANLINE_ORDER_LOWER_FIELD_FIRST; mSwapChainDesc.BufferDesc.Scaling = DXGI_MODE_SCALING::DXGI_MODE_SCALING_CENTERED; mSwapChainDesc.Windowed = true; mSwapChainDesc.OutputWindow = mhMainWind; mSwapChainDesc.BufferCount = 2; mSwapChainDesc.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT; mSwapChainDesc.SwapEffect = DXGI_SWAP_EFFECT::DXGI_SWAP_EFFECT_FLIP_DISCARD; mSwapChainDesc.SampleDesc.Count = 1; mSwapChainDesc.SampleDesc.Quality = 1; //這里采樣質量為1，開啟了采樣mD3DFactory->CreateSwapChain(mCommandQueue.Get(), &mSwapChainDesc,mSwapChain.GetAddressOf() )

需要注意的是，CreateSwapChain的第一個參數:

For Direct3D 11, and earlier versions of Direct3D, this is a pointer to the Direct3D device for the swap chain. For Direct3D 12 this is a pointer to a direct command queue (refer to ID3D12CommandQueue) . This parameter cannot be NULL.

• 既然報錯提示是多重采樣不支持，那么把多重采樣關閉就好了
  mSwapChainDesc.SampleDesc.Quality = 0;
  重新運行，一切正常
