Can you help me to understand Frame Gen and Upscaling? (lemm.ee)

Hello everyone, I have a 6600XT and I am just recently approaching these technologies. Everything I read on the web and on yt seems to contradict itself.

This is what I understand:

FSR (and Super res): it's upscaling and you can use it to make a game smoother (so technically I could go from 30 to 60 fps)?
AFMF is a frame generator so technically it's a win-more-condition, if I have 60 fps I can do better, but it doesn't improve something that isn't already fluid.

That said beyond the fact that FSR 2 (on Baldur's Gate 3 for example) makes everything a bit grainy and blurry compared to native resolution, I did this test:

BG3 on an ultrawide screen at 2100x900 high details, native runs me at 43 fps.

FSR2 (quality) + AFMF: I get 190fps

But 190fps goes beyond the 75Hz of my Freesync monitor. And the frame cap in game seems to turn off. Radeon Chill cannot be enabled, so is there a workaround? Other than using custom drivers like R.ID, which seem to be stuck at the March release?

But it really makes sense for soft pacing single player to have all that FPS without a frame cap? Do I understand well the case-scenario where I should use one or the other tech?

Thanks

Upscaling is the gpu creating a lower resolution frame, then filling in what would be there by guessing. Like, for a 4k frame it produces a 1440p frame then fills in the missing half of pixels. This gives more fps than if it did all the pixels.

Use this when you want the game to look better, but can't handle the fps at native resolution

Frame Gen is where it guess what the next fram will look like. So it essentially doubles the frames.

Use that when your fps is too low.

You don't need to, but you should probably turn one off. It's fine to go over your screen fps but over twice it is a little overkill

over twice it is a little overkill

That's my concern, I don't understand why on 6600XT I can't limit frame, from my test even FRTC can't be enabled :(
