A few months back I could run Battlefield 3 on ultra at around 180 fps but I got bored of it and I uninstalled. I wanted to play again so I reinstalled it a week ago and it could run the same. 2 days ago I could barely run it at 30 fps on low and I have no idea why, drivers are up to date, recently cleaned the dust, even reinstalled and my cpu/gpu usages are normal and have normal temperature.
My GPU:MSI GeForce GTX 750 Ti GAMING Twin Frozr IV OC 2GB DDR5 128-bit and my CPU:Intel Core i3-4170.
