I recently did a new Start on my PC. Everything was deleted and had to be intsalled again... But now I have 150FPS in Places I had 100-120 ish FPS... I really suggest to try it out guys
It's indeed a good idea, but it will take me 3 day to reinstall the day because my network suck. (450 kb/s, 600kb/s max). I took me an entire WEEK to download doom 2016.
My guess would be a setting that defaulted or a newer, more optimized driver than what you were running previously.
Maybe you just had clutter running in the back of your PC but with the fresh install PS2 gets more CPU time
