Everything you need to know
Common questions about DLSS Swapper and performance.
DLSS Swapper is an open-source tool that allows you to easily download and switch between different versions of DLSS, FSR, and XeSS DLL files in your games to potentially improve image quality or fix visual bugs.
No. This tool only works with games that already support DLSS, FSR, or XeSS. It cannot add upscaling technology to games that do not have it implemented by the developers.
This is a community resource site. The official project is hosted on GitHub. We provide links to the official releases for your convenience.
- OS: Windows 10 64-bit (Version 20H1, Build 19041 or later) or Windows 11.
- GPU: Any GPU (NVIDIA for DLSS; AMD/Intel/NVIDIA for FSR/XeSS).
For single-player games, it is completely safe. For multiplayer games with anti-cheat (e.g., Fortnite, Apex Legends, COD), modifying game files may risk a ban. Use at your own risk in online titles.
Newer DLL versions aren't always compatible with every game. If you experience crashes or visual bugs, simply use DLSS Swapper to revert to the original DLL version or try a different one.
