DLSS Swapper is a tool that allows you to download, manage, and swap DLSS, FSR, and XeSS dynamic libraries to upgrade or downgrade upscaling technology versions in games without requiring game updates.
Games ship with specific versions of upscaling libraries that may contain artifacts, performance issues, or lack newer features. DLSS Swapper solves this by letting you replace the bundled DLL files with different versions, enabling experimentation with newer or older implementations. The tool maintains backups of original files so you can restore them if a swap causes problems. It supports games from multiple platforms including Steam, GOG, Epic Games, Ubisoft Connect, Xbox App, and Battle.net, as well as manually added game installations.
You should adopt this tool if you own games using DLSS, FSR, or XeSS and want to test whether newer or older versions of these libraries improve visual quality or performance in your specific setup. It suits anyone willing to experiment with upscaling implementations and troubleshoot potential incompatibilities. The tool explicitly does not add upscaling support to games lacking it, and swapping libraries carries no guarantee of improvement—you may fix some issues or introduce crashes, though the backup system lets you revert changes.
The project maintains official download links and actively warns users against malicious impersonators. The tool supports multiple languages and provides structured templates for bug reports and feature requests, indicating organized community engagement processes.
