DXGI_SWAP_EFFECT_DISCARDUse this flag to specify the bit-block transfer (bitblt) model and to specify that DXGI discard the contents of the back buffer after you call IDXGISwapChain1::Present1. This flag is valid for a swap chain with more than one back buffer, although, applications only have read and write access to buffer 0. Use this flag to enable the display driver to select the most efficient presentation technique for the swap chain.DXGI_SWAP_EFFECT_SEQUENTIALUse this flag to specify the bitblt model and to specify that DXGI persist the contents of the back buffer after you call IDXGISwapChain1::Present1. Use this option to present the contents of the swap chain in order, from the first buffer (buffer 0) to the last buffer. This flag cannot be used with multisampling.
