I´ve got an Acer Nitro AN517-52 (Windows 11) and I get suddendly FPS drops in all games I play.(Battlefront 2, MW2 2022, Sea of Thieves, Valorant etc.).
Even tough the temperatures of my GPU and CPU are fine, I´ll get that FPS drops.
I´ve got this laptop for over one year now and before that time there were no FPS drops.
I am playing on a 4k monitor, but I set the resolution to 1080p, so this isn´t the problem as well.
I followed the steps of this tutorial (https://community.acer.com/en/discussion/656428/real-acer-windows-perofrmance-boost-guide-updated#latest) and it worked for one day but then the fps drops started to come again.
Here is an exemple about the fps drops
