I played csgo earlier today and my fps was good, hovering around 60-80 as usual. But now, when I open up the game, maximum I can get is 45fps in main menu. Ingame fps is around 25-30. How can I fix this problem? I have Intel Pentium G4400 processor @3.3ghz, Intel HD 510 and 8GB DDR4 2133MHZ ram. I installed newest Intel HD 510 drivers and also tried some other things, including launch options. Thanks, waiting
