For games that have FSR built-in you can enable it in the game settings, then it'll only scale up the game content while rendering the HUD at native resolution. And can use the better upscaling algorithms that rely on internal game engine data / motion vectors, should reduce artifacts.

The other cool things is they also have Frame Gen available in the driver to apply to any game, unlike DLSS FG which only works on a few games. You can toggle it on in the AMD software just below the Super Res option. I quickly tried it in a few games and it worked great if you're already getting 60+ FPS, no noticeable artifacts. Though going from 30=>60 doesn't work, too many artifacts. And the extra FPS are only visible in the AMD software's FPS counter overlay, not in other FPS counter overlays.

I recently got a Asus Rog Flow Z13 gaming "tablet" with the AMD Strix Halo APU. It has a great CPU + shared RAM + ridiculously powerful iGPU. Doesn't have the brute power of my previous desktop with a 4090, but this thing can handle the same games at 4k with upscaling on high settings (no raytracing), it's shockingly capable for its compact form factor.
