Dxgi swap effect. This effect is called tearing. The front buffer would be the buffer currently being displayed. Jan 10, 2026 · 说明 当使用 DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL 和 DXGI_SWAP_EFFECT_SEQUENTIAL ，又希望支持 MSAA ，必须使用另外一个单独的 Render Target ，在该目标上进行 MSAA 渲染，并将结果通过 ResolveSubresource 到 Swap Chain 的 Back Buffer 里。 DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL 性能最好，且支持的特性较多。 Nov 6, 2020 · DXGI_SCALING_STRETCH was the original behavior of doing a StretchBlt, with DXGI_SCALING_NODE being an option to have the image just drawn in the middle with a background color (only supported for DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL). This repo contains the DirectX Graphics samples that demonstrate how to build graphics intensive applications on Windows. - microsoft/DirectX-Graphics-Samples DXGI_SWAP_EFFECT_DISCARD 值： 0 使用此标志可以指定位块传输 (bitblt) 模型，并指定在调用 IDXGISwapChain1：:P resent1 后，DXGI 放弃后台缓冲区的内容。 此标志对具有多个后台缓冲区的交换链有效，但应用程序仅对缓冲区 0 具有读取和写入访问权限。 Jan 26, 2024 · For the flip model (DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL), values are: 0 - Cancel the remaining time on the previously presented frame and discard this frame if a newer frame is queued. - microsoft/DirectX-Graphics-Samples Aug 20, 2021 · The Direct3D 11. DXGI_SWAP_EFFECT_DISCARD Use 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. Apr 9, 2018 · Call to action If you are still using DXGI_SWAP_EFFECT_DISCARD or DXGI_SWAP_EFFECT_SEQUENTIAL (aka “blt” present model), it’s time to stop! Switching to DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL or DXGI_SWAP_EFFECT_FLIP_DISCARD (aka flip model) will give better performance, lower power usage, and provide a richer set of features. Jun 11, 2024 · Using DXGI_SWAP_EFFECT_DISCARD instead of flip discard circumvents the issue, but I'd like to use the flip model somehow. Instead of rendering new images directly to the monitor, the DXGI automatically draws your images onto a secondary buffer of pixels, called the back buffer. I found something that said that you should provide the *_SRGB format only for the render target view, not the backbuffer itself. The values are written to both the kernel-mode class key and its \UMD subkey, covering Swapeffect, Swapeffect_D3D, and Swapeffect_OGL. For an example that shows how sync-interval values affect a flip presentation queue, see Remarks. Mar 12, 2020 · 2 I have a Win32 non-game windowed app that uses a Direct2D device context/HWND render target to draw a window. Feb 24, 2026 · Both FSO scripts optionally configure the AMD DXGI swap effect via WMIC GPU detection. but trying that out only resulted in CreateRenderTargetView crashing instead. DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL と DXGI_SWAP_EFFECT_FLIP_DISCARD では、この最適化は、アプリケーションが画面に表示される唯一の項目である場合に発生する可能性があります。. To avoid this, the DXGI implements a feature called swapping. Oct 13, 2021 · You can specify DXGI_SWAP_EFFECT and DXGI_SWAP_CHAIN_FLAG values in the swap-chain description that pDesc points to. 1 runtime, which is available starting with Windows 8, provides a flip-model swap chain (that is, a swap chain that has the DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL value set in the SwapEffect member of DXGI_SWAP_CHAIN_DESC or DXGI_SWAP_CHAIN_DESC1). Microsoft recommends using the new flip model swap effects, either DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL or DXGI_SWAP_EFFECT_FLIP_DISCARD. See DXGI flip model for a high level overview of the technology. These values allow you to use features like flip-model presentation and content protection by using pre-Windows 8 APIs. In those cases, you provide the *_SRGB format only for the render target view, not the backbuffer itself. 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. Feb 2, 2023 · DXGI_SWAP_EFFECT_DISCARD Value: 0 Use 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. Is this possible? Jan 6, 2021 · Beginning with D3D9’s FLIPEX swap effect, and coming to DXGI through the FLIP_SEQUENTIAL swap effect in Windows 8, we’ve developed a more efficient way to put content on screen by sharing it directly with the desktop compositor, with minimal copies. 1 through 4 - Synchronize presentation for at least n vertical blanks. Currently it uses a DXGI swap chain with the DXGI_SWAP_EFFECT_DISCARD swap effect. DXGI_FORMAT_B8G8R8A8_UNORM DXGI_FORMAT_R8G8B8A8_UNORM_SRGB and B8G8R8A8_UNORM_SRGB are also supported as backbuffer formats when using 'older' presentation styles, but aren't directly supported for new flip style models DXGI_SWAP_EFFECT_FLIP_*. jng asy ebx grw xek oaw nxg jer hgq pjo yib iuj bng uop hfm
