[Solved]Lagg

Hi so i used to get a 40 fps and now im getting a 20 fps. I think this happend when i changed my 3d settings on Nvidia control panel but i dont know wat made me lag. Ive chnaged it to preformance but it stays at 15-20 fps

My video card is Nvidia GeForce Go 6100

here's a tip proven by me,

1. disk cleanup your system
2. defrag your system
3. config your startups
4. your some programs that can clean your pc, ex. CCLEANER/ADVANCE SYSTEMCARE
5. use GAME BOOSTER 2.2 to boost your gaming performance

and then tadaa, your PC will be as good as new
