With high-quality gaming on the rise, having good graphics performance is crucial. DLSS Swapper is a helpful tool for gamers who want to use NVIDIA’s DLSS (Deep Learning Super Sampling) technology without waiting for official game updates. This free application lets users switch between different versions of DLSS .dll files in their games. This could potentially improve graphics performance and frame rates in supported games.
If you’re a gamer looking to enhance your system’s visual performance, understanding how DLSS Swapper works is important. The tool lets you choose between different versions of NVIDIA’s DLSS, giving you control over the balance between image quality and performance. You can do this by downloading and using different DLSS dynamic-link libraries, which are important parts of the AI-driven upscaling process.
What Is DLSS Swapper?
DLSS Swapper is a free open-source tool that lets you manage and update NVIDIA DLSS, AMD FSR, and Intel XeSS DLL files across your installed PC games.
It allows you to:
- Update outdated DLSS versions in games to the latest (e.g., DLSS 3.1 → 3.10.3).
- Swap FSR 3.1 to FSR 4 or test new versions of AMD’s upscaling tech.
- Easily back up and restore original DLLs.
- Manage Frame Generation (FG) and Super Resolution (SR) versions separately.

⚙️ How DLSS Swapper Works
Games that use DLSS, FSR, or XeSS rely on small library files (DLLs) — such as:
nvngx_dlssg.dll(DLSS Frame Generation)nvngx_dlss.dll(DLSS Super Resolution)amd_fidelityfx_fsr3_api.dll(FSR 3)libxess.dll(XeSS)
DLSS Swapper scans your system for these files, then allows you to replace them with newer versions downloaded directly from official SDKs or community sources.
🪜 Step-by-Step Guide
1. Download and Install DLSS Swapper
- Go to the official GitHub page: DLSS Swapper Releases
- Download the latest
.exeversion (e.g.,DLSSSwapperSetup-1.2.0.2.exe). - Install it — no admin rights are typically required.
2. Scan for Installed Games
- Launch DLSS Swapper.
- It will automatically detect supported games (Steam, Epic, Ubisoft, etc.).
- You can also manually add a game folder if it’s not detected.
3. Check Current DLSS/FSR/XeSS Versions
- Select a game from the list.
- DLSS Swapper will show which upscaling DLLs are present and their versions.
- Example:
DLSS Super Resolution v2.5.1 - Example:
DLSS Frame Generation v3.1.0
- Example:
4. Update or Swap DLSS Versions
- Click “Download Latest” next to the DLSS version you want to update.
- DLSS Swapper will fetch the latest available version (e.g., 3.10.3) and replace the old one.
- You can also swap manually by selecting a specific version from the dropdown.
🧩 Tip: Always back up the original DLLs before swapping — DLSS Swapper can do this automatically.
5. Upgrade FSR 3 to FSR 4 (Optional)
As of November 2025, DLSS Swapper supports AMD FSR 4 integration.
You can replace FSR 3 DLLs in supported games to test FSR 4 improvements.
How to do it:
- Download the latest AMD FSR 4 SDK (included in DLSS Swapper’s update list).
- In a game using FSR 3, choose “Replace with FSR 4”.
- DLSS Swapper will rename and inject the correct FSR 4 DLLs.
⚠️ Note: Not all games are guaranteed to work perfectly — FSR 4 is backward-compatible with many FSR 3 titles but may require testing.

6. Launch the Game and Verify
Once swapped:
- Start the game.
- Enable DLSS, FSR, or XeSS in the graphics settings.
- You can optionally enable “Display DLSS Info” in DLSS Swapper to confirm the new version is active.
🧩 Troubleshooting Tips
| Issue | Possible Fix |
|---|---|
| Game still shows old DLSS version | Delete cached shaders or verify game files, then reapply swap |
| DLSS swap not detected | Ensure correct DLL filename (e.g., nvngx_dlss.dll) |
| Game crashes after swap | Revert to backup DLL (DLSS Swapper keeps one automatically) |
| FSR 4 not working | Try renaming manually or wait for official support in DLSS Swapper updates |
🧰 Advanced Options
- Preset Selection: Choose DLSS presets (A–K) for different performance/quality balances.
- Profile Tweaks: Adjust settings via NVIDIA Profile Inspector for better compatibility.
- Auto Updates: Enable automatic SDK updates for DLSS, FSR, and XeSS.
