I'm asking for an acquaintance, as he recently has an issue where he has trouble to get even Wallpaper Engine running, and playing Genshin Impact on roughly 10 FPS. At the moment he has reinstalled GeForce drivers and lifted his laptop up (He always does this anyway). I asked him about reinstalling Windows but he said it would mess up his coding environment and parameters so he is very reluctant.
His specs are in the title, but for more information: Acer Nitro 5 AN515-57, i5-11400H, 16GB 3200 MHz, RTX3060 6GB
He is aware of his laptop's age, but I wouldn't be asking here if he has the money to buy a replacement.
People of Reddit, thank you !
P.S: I'd like to add, his GPU ran on low wattage upon startup, doing u/Fickle_Appearance421's trick works but have to do it every single time on startup, I think this has to do with the drivers but then reinstalling doesn't work.
