Since DLSS launched, there have been many versions of it and developers rarely update the DLSS libraries of their games when a new version rolls out. Fortunately, a developer has created a tool that lets you update the DLSS library of any supported game you have installed.
You can easily update DLSS for any DLSS-compatible game by replacing the library files. Sometimes, updating comes with improvements, but there are also times where it introduces issues, but at least you can easily roll back if you've found any issues. Even if you don't have a backup, TechPowerUp has a database of all DLSS libraries, so you can download the original DLSS library for a particular title if you encounter problems with an updated version.

Now thanks to a developer called Brad Moore (via VideoCardz), updating the DLSS library of your games will become much easier with DLSS Swapper. With this tool, you'll be able to select which DLSS library you want to use, download it and replace the DLSS library files currently in use. To update to a new DLSS version, DLSS Swapper will rely on the TechPowerUp database, but you may also update the library yourself using your library files obtained elsewhere.
The DLSS Swapper tool is not available in a compiled version yet, but it should release soon. In the meantime, you can download the files already through Github and compile the tool yourself.
