FSR not working (even after following the instructions to the letter)

Hi guys! Yes I am running it at below max resolution, and yes I have the filter on, and yes I have the game set to windowed.

What happens, is when the game is not windowed on performance overlay 4 nothing happens swapping resolution. On windowed mode, when I change to a lower resolution, FSR flickers green for less than a second then goes to off again. Have tried this on like 10 games, not a single one works. They all flicker to on then turn off. I am testing on games that don't have native fsr build in either. Everything online instructions i seem to have followed and they all have the same instructions of windowed + filter on + below max and that just doesn't work for me. FSR DOES work in games that have it supported though. And I can use decky to patch FSR frame gen into games, but just getting the basic upscale does not seem to work

Anyone have a similar issue and/or debug suggestions? Thank you!
