## In short

The route depends on DX9, DX11, DX12, Vulkan or OpenGL. The game's video menu, RivaTuner's overlay or ReShade.log tell you which one is live.

## Steps

1. Look for a DirectX 11 / DirectX 12 / Vulkan option in the game's video settings.

2. RivaTuner's on-screen display labels the API next to the FPS.

3. After a Feeder install, ReShade.log names the API it hooked.

4. Match the Swapper route to it; restore before switching APIs.

## Facts that do not change

Free and MIT. RTX 20/30/40/50 on Feeder. F8 overlay on 64-bit DX11/DX12 Feeder and RenoDX. Restore originals before online play.

## FAQ

### What is DLSS 5 Swapper?

A free MIT-licensed Windows app that installs, tunes and restores NVIDIA DLSS 5 Neural Rendering across native DLSS games, non-DLSS games via DLSS5-Feeder, and supported emulators.

### Which GPUs work?

RTX 20, 30, 40 and 50 Series for the ReShade/Feeder routes. The bundled OptiScaler neural model is Blackwell-only; older cards need a supplied modded nvngx_dlssnr.dll.

### Do games need native DLSS?

No. Native titles upgrade in place; games without DLSS use the DLSS5-Feeder 1.17.0 + ReShade 6.8.0 route on DX9/11/12, Vulkan and OpenGL.

### How do I undo everything?

Select the game and click Restore originals. Uninstalling the app alone does not touch game folders.

### Is it safe for online games?

No. Treat it as a single-player tool. Injected DLLs can trigger VAC, Easy Anti-Cheat or BattlEye. Restore originals before online play.
