I have already installed this one but won't work!https://github.com/BeatPlay/BetterAmphetaminPlugin/releases
Here is a better amphetamin plugin called BetterAmphetamin
Just put the .suprx file and the config.txt in uxlugins and hold "select" for 2 seconds
There you go
Thanks for the help but the game is still enjoyable and smooth in it's default framerate anyway haha ^^
