Fxaa shader, g. These code snippets demonstrate how to set up an anti-aliasing filter that smoothes the image displayed on the screen. It covers their implementation mechanisms, configurable variables, and the files involved. . txt, shaders, and binary patches work, see How Graphic Packs Work. Feb 28, 2021 · We need a pass to apply FXAA, so add it to the PostFXStack shader, along with a corresponding entry in the PostFXStack. Address = Clamp; Filter = None; VertexShader = compile GLSL VS_FSQUAD; FXAA is a simple and fast post-filter that blurs sharp edges, while TAA uses data from previous frames to produce a smoother image, especially when there is movement. We'll indicate this via the LUMINANCE_GREEN shader keyword. Nvidia) behind FXAA and new variants are developed regularly. There are many ressources available for the exact math (e. FXAA quality parameters $subPix, $edgeThreshold, and $edgeThresholdMin are only active when $fxaa == 2. For the global FXAA filter applicable to 3 days ago · FXAA is implemented via a replacement pixel shader matched by its hash. 0. Part of the code, namely the implementation of TAA, was taken from TAA Project, so the license is MPL-2. shader shader / lava shaders / ocean shaders / sky shadow / contact shadowmap shadowmap / performance 3 days ago · Mario Kart 8 Relevant source files This page documents all graphic packs available for Mario Kart 8 in the src/MarioKart8/ directory. The pass is a copy of Final Rescale renamed to FXAA and with its fragment function set to FXAAPassFragment. Because it operates on the output image rather than on individual game shaders, it requires no game-specific knowledge and can be applied 3 days ago · The FXAA filter's rules. Apr 21, 2023 · The key takeaway here is that FXAA is a cheap and effective algorithm for producing smoother images. Jan 21, 2011 · What is the difference between FXAA and TAA? FXAA is a simple and fast post-filter that blurs sharp edges, while TAA uses data from previous frames to produce a smoother image, especially when there is movement. It has been created by worstplayer. 3 days ago · FXAA Filter Pack directory: Filters/FXAA/ FXAA is a screen-space anti-aliasing algorithm that detects edges in the final image using local contrast and blends neighboring pixels to soften jagged edges. txt also has a titleIds = that is blank, meaning it applies globally to all games — unlike game shader replacements, which are scoped to specific titles. Mar 30, 2018 · The actual FXAA pass then uses that texture instead of the original source. Pass enum. It has some drawbacks (no smoothing pixels of different colors with the same luma, and has difficulties with some corners). Furthermore, the FXAA pass needs to know whether it should use the green or alpha channel for luminance. Aug 24, 2012 · The advantage of the alternative FxAA shader is that it does less texture lookups, and has less branches, resulting in better and more consistent performance, at the cost of lower accuracy. For a general explanation of how packs are built and how rules. Aug 24, 2025 · For some reason camera addons (I checked on this and this ) have weird compatibility with this shader, zooming/moving camera image.
