Install FSR4 Injector on Steam Deck
FSR4 Injector is a Decky Loader plugin. With DeckyHub installed, open DeckyHub's Discover tab in Gaming Mode, search for FSR4 Injector and press Install. DeckyHub hands the release to Decky Loader's own installer and checks its SHA-256 whenever GitHub publishes one. You can also download the ZIP from its releases and install it by hand from Decky's developer settings.

Security scans
Every ZIP DeckyHub offers is scanned with ClamAV and with YARA rules (YARA Forge's core set), and the same scans are shown in the app. VirusTotal and MetaDefender results are matched by the file's SHA-256, so the file itself is never uploaded.
