RHI — ReShade HDR Installer

One tool. Every game. Full HDR, DLSS, and NVIDIA driver management from a single window.

RHI detects your entire game library across every major store and handles ReShade, HDR mods, frame limiters, DLSS management, OptiScaler, shader packs, and NVIDIA driver profiles — all in one click.

What It Does

One-Click HDR for Every Game

• RenoDX — auto-detects and installs the right HDR mod for each game. Hundreds of bespoke game-specific mods, plus generic HDR support for every Unreal Engine and Unity game without one.
• UE-Extended — the default for all Unreal Engine games without a named mod. Automatically configures reshade.ini and Engine.ini with the correct HDR settings. No manual ini editing.
• Luma Framework — every DX11 Unreal Engine game in your library gets a Luma row automatically. Named mods for supported titles, generic support for everything else. Engine.ini keys, launch args, and TAA settings applied from the wiki automatically on install.
• DXVK + Lilium HDR — brings scRGB HDR output to older DX9 games that normally have no HDR path at all.
• RenoFX HDR Toolkit — SDR-to-HDR conversion for any game that doesn't have a dedicated RenoDX mod yet.

ReShade — Fully Managed

RHI replaces the ReShade installer entirely.

• Detects each game's graphics API via PE binary scanning and names the DLL correctly — dxgi.dll, d3d9.dll, opengl32.dll — automatically.
• Latest stable and nightly builds staged on every launch.
• Per-game channels: Stable, Nightly, Custom, Legacy, or No Addons. Mix freely across your library.
• Vulkan games use the global implicit layer — one-click install, no manual steps.
• Foreign DLL detection: if another tool (DXVK, Special K, ENB) is already in the game folder, you're warned before anything is overwritten.
• reshade.ini seeded and merged automatically — hotkeys, screenshot path, peak brightness, and DLSS paths all set without any manual configuration.

DLSS 5 and Neural Rendering

• DLSS5 Feeder — full pipeline install in one click: deploys feeder addon, DLSS5 consumer, nvngx_dlss.dll, nvngx_dlssnr.dll, pre-configured ReShadePreset.ini, and required shader packs. Auto-selects the right method for your game (32-bit, DX11, DX12).
• ShortFuse DLSS Tool — alternative neural rendering implementation for DX12 games.
• DX11 Bridge variant — DLSS5 Tool + bridge for games that need DX11 compatibility.
• NR Cost Scaler — wraps nvngx_dlssnr.dll to run neural rendering at reduced cost (default 75%). Toggle before installing a method to deploy it automatically.

DLSS and Streamline Version Manager

• Swap SR, RR, FG, and Streamline versions per game from a dropdown. Every version from 2.x to current, plus Custom.
• Original DLLs backed up automatically. Restore the originals any time.
• Set global defaults once — Quick Apply pushes them to any game in one click.
• Batch Deploy: select multiple games from a checklist and push versions, presets, and render scales to all of them at once.
• DLSS presets (J/K/L/M for SR, D/E for RR, A/B for FG) written directly to NVIDIA driver profiles. No Profile Inspector needed.
• DLSS SR Render Scale Override — force 33–100% render resolution per game.
• NVIDIA Override — set the driver's "Latest DLL" flag per component directly from the version dropdown, equivalent to enabling it in NVIDIA App or Profile Inspector.
• Auto-update for DLSS SR, RR, and FG from the RHI manifest. Opt-in per-game.

Multi Frame Generation

• RTX 40 MFG Unlock — enables DLSS MFG multipliers beyond 2x (up to 6x) on RTX 40 Series via Ultimate ASI Loader. One-click install from the Extras section.
• MFG Ada Unlock — in-memory MFG unlock addon for RTX 40 Series via the addon manager.
• RTX 50 Series MFG — configure Fixed or Dynamic MFG mode, frame count (2x–6x), and dynamic target frame rate from the DLSS section.

OptiScaler

• Redirects DLSS API calls to FSR4/FSR3/XeSS for AMD and Intel GPUs, and adds frame generation support where the game doesn't have it.
• Stable and Nightly channels per game, selectable in the cog.
• Per-GPU INI templates — six pre-configured templates (NVIDIA, AMD+DLSS, AMD no-DLSS, each in Stable and Nightly). Seeded on first launch, user-editable, never overwritten.
• Streamline + DLSS Enabler deploy (Nightly) — toggle per game to deploy Streamline DLLs and DLSS Enabler to the OptiScaler folder. Pick the Streamline version per game.
• Frame Generation settings: FG Input, FG Output, FG Nvngx Replacement, HUD Fix — all configurable in the cog.
• OptiPatcher auto-deployed to all games with OptiScaler installed. Auto-updates silently.
• ReShade coexistence handled automatically — filenames adjusted, LoadReshade=true set.

Frame Limiters

Two per-game frame limiters, mutually exclusive:

• ReLimiter — precision frame pacing with predictive sleep, phase-locked timing grid, and closed-loop correction. VRR-aware, DLSS FG adaptive, Reflex-integrated.
• Display Commander — alternative limiter supporting both 32-bit and 64-bit games.

Both deploy as ReShade addons. Both participate in Update All.

NVIDIA Driver Profile Management — Replaces NVIDIA App and Profile Inspector

All per-game driver settings written directly via NvAPI. No NVIDIA Profile Inspector, no NVIDIA App needed.

Per-game overrides:

• VSync Mode, Tear Control, Low Latency (Off/On/Ultra)
• Smooth Motion: Enable, Allowed APIs, Flip Pacing — automatically sets Low Latency to Ultra when enabled
• Power Management Mode
• G-Sync per-game toggle
• ReBAR: Enable (Off/On/Auto), Mode (Standard/Optimized), Size Limit
• RTX HDR: Enable/Configure with Peak Brightness, Contrast, Saturation, Middle Grey, Debanding
• DLSS Presets and Render Scale Override (no admin required)

Global settings (base profile):

• Shader Cache Size and Pre-Compile
• G-Sync Mode and Preferred Refresh Rate
• Global ReBAR
• FPS Limit (Frame Rate Limiter V3)
• Digital Vibrance per display — restored automatically on every app startup

Export/Import: back up all per-game NVIDIA profiles to a JSON file. Import restores everything after a driver reinstall.

HDR Auto-Toggle

Enables Windows HDR when you launch a game through RHI and disables it when the game closes. Works with Steam, Epic, Xbox, and direct exe launches. Per-game override button next to Launch — purple when active.

Shader Pack Management — 46 Packs

Every shader pack you'd ever want, all managed in one place:

• Essential: Lilium HDR Shaders (EndlesslyFlowering) — required for HDR tone mapping
• Recommended: crosire reshade-shaders, PumboAutoHDR, MaxG2D Simple HDR, clshortfuse shaders, RenoFX HDR Toolkit, smolbbsoop shaders
• Extra: 39 additional packs — SweetFX, OtisFX, qUINT, iMMERSE, Prod80, CorgiFX, ZenteonFX, CRT-Royale, VRToolkit, GShade-Shaders, QD-OLED APL Fixer, LumaBoost, and more

Select packs globally or override per game. Expand any pack to pick individual .fx files — tri-state checkbox for partial selection. Save selections as named profiles, export as zip, share directly into Discord.

Custom shaders go in %LocalAppData%\RHI\Custom\reshade\Shaders\ — RHI deploys them alongside managed packs.

ReShade Addon Management

Global addon manager from the toolbar. Enable/disable per game or globally. Custom addons in %LocalAppData%\RHI\Custom\Addons\ automatically appear in the picker.

Update All

One button in the toolbar updates ReShade, RenoDX, ReLimiter, Display Commander, OptiScaler, and RE Framework across your entire library. Per-game update exclusions respected. Lights up purple when updates are available.

Background check every 4 hours while running — works from the system tray without keeping the window open.

Manifest-Driven Updates

Game data, mod links, Engine.ini configurations, launch fixes, and feature flags are all driven by a manifest fetched from GitHub on every launch. This means:

• New game support, fixes, and tweaks deploy to all users immediately — no app update needed
• Per-game Engine.ini overrides (like Black Myth: Wukong's custom HDR keys) delivered server-side
• Feature flags enable dev-preview features for all users via manifest toggle
