FSR 4 may be a simple upgrade for FSR 3.1 games according to leaks, which hopefully means we won't see a repeat of FSR 3's poorly-supported launch

Black Ops 6.

I remember the FSR 3 launch. While AMD's version of Frame Generation was a boon for those of us not on Nvidia GPUs, the supported games list was made up of, err, two entries. Hopefully that won't be the case with FSR 4, however, as according to a reliable source of leaks, when it comes to backwards compatibility, "it should just work."

Exactly how it "should just work" is currently unclear (via Wccftech). According to @Kepler_L2, one of the more reliable leakers of modern times, AMD's RDNA 4 driver will simply replace the FSR 3.1 DLL with FSR 4. Whether that's applied by default on all FSR 3.1-supported games, or a manual, game-by-game process, is up for debate.
