# RenoDX RenoDX ("Renovation Engine for DirectX Games") is a modding toolset for PC games. Mostly used to give games proper native HDR when they ship without it, or with a bad implementation (washed-out blacks, clipped highlights, or "HDR" that's really SDR stretched out). It's an [[Open Source]] project started by ShortFuse (clshortfuse on [[GitHub]]) in February 2024, under the [[MIT License]]. Community modders write most of the per-game mods. As of October 2026 the repo is still active (last push on 2026-10-04). ## Why it exists Plenty of games render internally in high dynamic range, then squash everything to SDR at the very end of the pipeline. Others bolt on an HDR mode that looks worse than their SDR output. Fixing either from the outside means changing how the game produces its final image. ## How it works RenoDX is built on ReShade's add-on system. ReShade handles the DirectX hooks, so RenoDX doesn't patch each game's executable (which would break with every game update). On top of that, it can: - Replace the game's tone mapping and post-processing shaders with rewritten ones - Upgrade swapchains to an HDR-capable output format - Upgrade texture resources, moving render targets to higher precision so the extra range isn't thrown away halfway through the pipeline - Inject buffers and add overlays, which is how settings like peak brightness, tone mapping and color grading show up in an in-game menu - Write user settings to disk, so tweaks survive a restart ReShade gives it wide compatibility, but every mod is still hand-made for one game. ## Coverage The [[PC Gaming Wiki]] page lists **254 game-specific mods** marked as playable (October 2026), including Cyberpunk 2077, Elden Ring, Baldur's Gate 3, Hollow Knight: Silksong, Final Fantasy VII Rebirth, the Resident Evil remakes and most of the Assassin's Creed series. Musa alone maintains 55 of them. Voosh, Ritsu, OopyDoopy and ShortFuse each have more than 20. That number is possible because of how the work is split: ShortFuse built the shared engine once, and each modder only writes the game-specific part. There are also generic mods for Unreal Engine 4, Unreal Engine 5 and Unity. They can give native HDR to games without a dedicated mod, though some games need tweaks; the compatibility list on the GitHub wiki says which. ## Getting the mods Mods are distributed on Nexus Mods, as snapshot builds linked from the GitHub wiki, and on the project's [[Discord]] server. Usual install: put ReShade (with add-on support) next to the game executable, then drop the mod's `.addon64` file beside it. ## Extra tools - An FPS limiter add-on - A devkit add-on for modders building new mods. The repo also documents a live devkit + [[Model Context Protocol (MCP)]] workflow, so an AI agent can take part in shader work - A decompiler for Shader Model 6.0+ shaders, the format newer DirectX 12 games ship ## References - PCGamingWiki: https://www.pcgamingwiki.com/wiki/RenoDX - GitHub repository: https://github.com/clshortfuse/renodx - Website: https://renodx.com/ ## Related - [[PC Gaming Wiki]] - [[Open Source]] - [[MIT License]] - [[Model Context Protocol (MCP)]]
