Prism

Description

Prism is a free, open-source Windows app that installs graphics mods into your games and keeps track of every file it touches.

I made it because setting up DLSS 5, multi frame gen or RenoDX HDR by hand means juggling DLLs, ReShade versions, ini files and Streamline packages, and when something breaks you have no idea what's still in your game folder. Prism does the installs for you, checks the files before writing them, and lets you undo everything with one click.

It doesn't ship any third-party files. Everything is downloaded from the official source (RenoDX, rhi-repo, OptiScaler, NVIDIA's Streamline SDK, reshade.me) and checked (NVIDIA signature or pinned SHA-256) before it goes into your game.

Installation instructions

1. Download Prism-Setup (installer) from the Files tab, or the portable zip if you prefer.

2. Run the installer. It installs for your user only, no admin rights needed.

3. Start Prism. It asks for admin rights at launch, because a lot of games live in Program Files.

4. Pick a game, choose what you want (DLSS, frame gen, HDR), press Install. Prism downloads what's missing and sets it up.

5. Close the game before installing anything. Prism refuses to write while the game is running.

To remove something, use Remove next to it in the "Added by Prism" list, or Reset injections to bring the game back to how Steam/Epic/etc. installed it.

Prism updates itself from GitHub, you don't need to come back here for every version.

Windows warnings: Prism isn't code-signed yet. SmartScreen may say "Windows protected your PC" (More info > Run anyway). If Smart App Control blocks a brand new version, wait a few days or use the previous one. Every file has a .sha256 on GitHub if you want to check it.

Main features

DLSS 5 / Neural Rendering

- RenoDX DLSS (ShortFuse's add-on or DLSS5 Tool) with the full stack: DLSS 310. 9. 1, Streamline 2. 14. 1 and the neural runtime that matches your GPU

- OptiScaler DLSSNR paths, DLSS 5 Bridge for DX11/Vulkan games

- A diagnostic that reads the game's ReShade.log after you play and tells you if the neural pass is really working, degraded or failing (the overlay can say "active" when nothing changes)

Frame generation

- Paths filtered by GPU: native MFG on RTX 50, RenoDX MFG Unlock / RTX40MFG-Unlock on RTX 40, ported DLSS-G on RTX 30 and 20

- Frame gen in games that don't have it (DX12 + DLSS/FSR/XeSS): OptiScaler DLSS FG (NVIDIA's frame gen, x2 on RTX 40, up to x4 on RTX 50) or OptiScaler FSR FG (x2, any GPU)

- Only real multipliers are shown, no fake x4 where the mod only does x2

- Reads the RenoDX mod list live and picks the right mod for each game

- Applies the notes from the wiki: resource upgrades, Upgrade Path, Engine.ini (written read-only)

- Unreal Engine Extended for any UE4/UE5 game, respecting the presets built into the mod

- Keeps your ReShade if it's already the add-on build 6. 8+, replaces an old/standard one in place, picks a DLL name that doesn't clash with OptiScaler

Clean up and undo

- Every file Prism writes is tracked per game, originals are backed up

- Reset injections: removes everything added to a game, by Prism or by other tools

- Deep clean: removes leftovers from RHI (.original files, rhi_install.txt) and OptiScaler under any DLL name, even from before you used Prism. Shows the full list first and can be undone

- Conflict warnings (two ReShade, two OptiScaler, two DLSS add-ons...)

- Finds games from Steam, Epic, GOG, Xbox, EA, Ubisoft, Battle.net, plus any game you add by its .exe

- 18 languages, two themes

Requirements

- Windows 10 (1809 or newer) or Windows 11, 64-bit

- NVIDIA RTX 20 series or newer for the DLSS paths. ReShade, RenoDX HDR and FSR frame gen work on any GPU

- Internet connection (components are downloaded when you install them)

- Most paths need DirectX 12. The app tells you which ones fit each game

- Nothing else to install, the . NET runtime is included

Use it on single-player games. Don't inject mods into games with anti-cheat or online play, you risk a ban.

Shout outs

Prism only installs other people's work, so all the credit for the mods goes to them:
