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.
