Basically for games that only support DLSS, it’s long been possible to replace the DLSS files to force the game to use FSR 2/3 instead. It’s a pretty common mod available for many games on Nexus mods.

Sometimes it works well, other times you get weird blurring or other effects.

This is an interesting-development deck plugin that will greatly simplify the installation of these mods to games, letting us benefit from FSR upscaling and frame gen in DLSS only titles.
