What is it?

RHI (ReShade HDR Installer) is a Windows desktop application that scans game libraries from major stores, including Steam, Epic, GOG, Xbox, EA App, Ubisoft Connect and Battle.net, and installs post-processing and HDR tooling into each game. It replaces the ReShade installer, detecting each game's graphics API to name the correct DLL, and automatically selects matching RenoDX, Luma Framework or UE-Extended HDR mods where available.

Beyond HDR, the app manages DLSS SR, RR and FG versions per game with backups of original DLLs, writes DLSS presets and render scale overrides into NVIDIA driver profiles through NvAPI, and deploys OptiScaler for AMD and Intel GPUs. It also includes two per-game frame limiters, ReLimiter and Display Commander, a shader pack manager covering dozens of packs, and an Update All button for ReShade, mods and related components.

RHI requires Windows 10 or 11 and the .NET 8 Desktop Runtime. An NVIDIA GPU is needed for driver profile features, while ReShade and RenoDX work on other GPUs. Some features, such as ReBAR and Smooth Motion, need admin rights.
