USA mountain time

I did not realize that DLSS3 had been added to the game, so I wanted to try it out. Turned it on and automatically get stuttering and my framerate goes down like 10-15 fps less. Card usage drops from 100% to around 60-70%. Anyone else experiencing something similar? I've got a 4090 and a Ryzen7 7800X3D...

So, I did the whole game and everything a level could ask, no death, gold score, all prizes etc... I'm pretty sure I did the 100% but despite that, it says I'm at 99% costume and 97% mastered (which I'm pretty sure I did every, single, level 100%) any idea what could be the problem? heard if you do everything, you can unlock the famous crown from the previous LBP games, but that sure did not happen. (I also have all the free dlcs costume wise)...
