OptiScaler - Upscaling for All GPUs

DIFFICULTY: BEGINNER UPDATED:

>> INTRODUCTION

🇩🇪 Deutsche Version
OptiScaler GPU Upscaling Technology

🎮 WHAT IS OPTISCALER?

OptiScaler lets you use DLSS, FSR and XeSS in games – regardless of your graphics card!

Got an AMD card and the game only offers DLSS? No problem – OptiScaler uses the DLSS inputs for FSR or XeSS!
Intel ARC and FSR3? Works too!
NVIDIA and XeSS? Easy!
(DLSS itself as an upscaler still only runs on NVIDIA RTX cards.)

⭐ NEW: OPTISCALER MANAGER (CLIENT)

The Optiscaler Client (unofficial community tool) is a modern manager that makes installing OptiScaler incredibly easy!

✓ Auto-detects Steam, Epic, GOG, EA, Ubisoft, Battle.net, Xbox games
✓ One-Click installation for all your games
✓ Manages components like Fakenvapi, Nukem's DLSSG-to-FSR3
✓ Single-File EXE – no installation required

→ Download Optiscaler Client

⚠️ IMPORTANT WARNING:

DO NOT use with online games!
Anti-cheat software may detect OptiScaler as a cheat and ban you!

>> PREREQUISITES

🖥️

Windows 10/11

Up-to-date Windows with latest updates

🎮

A game with DLSS/FSR/XeSS support

The game must support at least one upscaler

📦

7-Zip or WinRAR

To extract OptiScaler files

>> STEP-BY-STEP GUIDE

1

Download OptiScaler

  1. Go to github.com/optiscaler/OptiScaler/releases
  2. Find the latest version (at the top)
  3. Click on Optiscaler_X.X.X.7z to download
💡 TIP: Always get the latest version – it has the most features and bug fixes!
2

Extract the 7z archive

  1. Right-click on the downloaded .7z file
  2. Select "7-Zip → Extract Here" or "Extract All..." (Windows 11)
  3. You'll get a folder with these files:
    📁 OptiScaler_vX.X.X/
    ├── 📄 OptiScaler.dll
    ├── 📄 OptiScaler.ini
    └── 📄 (more files...)
3

Find your game folder

You need to find the folder where your game is installed:

🎮 STEAM:

  1. Open Steam, go to your Library
  2. Right-click on the game → Manage → Browse Local Files

🎮 EPIC GAMES:

  1. Open Epic Games Launcher → Library
  2. Click on the three dots (...) next to the game → Manage
  3. Click on the folder icon

🎮 GOG:

  1. Open GOG Galaxy → Library
  2. Click on the game → Settings icon → Manage installation → Show folder
4

Copy OptiScaler files to the game

Copy the OptiScaler files to the same folder as the game's .exe file:

  1. Open the extracted OptiScaler folder
  2. Select all files (Ctrl + A)
  3. Copy them (Ctrl + C)
  4. Go to the game folder (where the .exe is)
  5. Paste (Ctrl + V)
  6. Rename OptiScaler.dll to dxgi.dll (alternatives: winmm.dll, version.dll, d3d12.dll …) – or run the included setup script (.bat), which does it for you
✅ IT SHOULD LOOK LIKE THIS:
📁 Your_Game_Folder/
├── 📄 Game.exe (your game)
├── 📄 dxgi.dll (OptiScaler, renamed)
├── 📄 OptiScaler.ini (OptiScaler)
└── 📁 (other game folders...)
⚠️ NOTE:

Some games have the .exe in a subfolder like bin/ or Game/Binaries/Win64/. OptiScaler files must ALWAYS be next to the .exe!

Launch game & configure OptiScaler

  1. Launch the game normally
  2. Go to the game's Graphics Settings
  3. Enable DLSS, FSR or XeSS (any of them!)
  4. Press INSERT in-game to open the OptiScaler menu
OptiScaler In-Game Overlay Menu

The OptiScaler In-Game Overlay Menu

🎛️ IN THE OPTISCALER MENU YOU CAN:

  • • Switch upscalers (DLSS ↔ FSR ↔ XeSS)
  • • Adjust sharpness
  • • Enable Frame Generation (OptiFG)
  • • Show performance stats (Page Up/Page Down)
ℹ️ KEYBOARD SHORTCUTS:
INSERT = Open menu
Page Up = Show stats
Page Down = Cycle stats
Alt+INSERT = If INSERT doesn't work

>> COMMON ISSUES

❓ The menu won't open!

→ Make sure you're in-game (not in main menu)
→ Try Alt + INSERT instead of just INSERT
→ Check if you enabled DLSS/FSR/XeSS in the game settings

❓ The game crashes!

→ Delete the OptiScaler files and download the latest version
→ Some games need special settings – check the Wiki

❓ How do I remove OptiScaler?

→ Simply delete all OptiScaler files from the game folder (dxgi.dll or whichever name you renamed it to, OptiScaler.ini, etc.)
