DLSS Updater has been released in version 4.8.0 - shortly after version 4.7.1, which fixed a stale backup path bug.
The tool scans the games installed on a system and replaces outdated DLSS, XeSS, and FSR DLLs with newer versions - including automatic backups for rollback. Version 4.8.0 adds support for Ray Reconstruction 4.5 (preset F), selectable directly in the application.
