1.1.1
Download, manage, and swap DLSS dlls to update or downgrade DLSS in games without needing a game update.
DLSS Swapper is a tool that allows you to conveniently download, manage, and swap DLSS dlls allowing you to upgrade or downgrade DLSS version in a game without the game needing an update. DLSS Swapper supports FSR 3.1, XeSS, XeSS Frame Generation, and XeLL technologies. This tool does not allow you to add DLSS to games that don’t support it.
This tool does NOT guarantee that swapping DLSS dlls will:
Improve DLSS performance.
Reduce DLSS artifacts.
Give a crash free experience.
In many cases you may fix some issues, in other cases you may prevent a game from launching (until you restore your original dll, provided in the tool).
Minimum System Requirements
Windows 10 64-bit (20H1, build 19041)
While a Nvidia GPU is not a requirement to run DLSS Swapper, it is a requirement to use DLSS.
