I have this problem that I get low fps in games. For example today I got solid 80 fps in Leauge of Legends. Few hours later its stuck to 23 fps and wont go over. Yesterday I had same problem. I have all drivers updated I even reinstalled drivers but nothing. I have been having 23 fps issues for quite few months. Its like stays for few days and goes away or something like that. I had my computer also recently cleaned(about 3 months ago) also had new thermal paste applied. So my question is any idea what might cause those fps issues and why is my fps capped at 23 on Leauge of Legends.I havent tried other games since I had my Windows reinstalled so I dont know about them but I remember I had about 30 fps on fallout new vegas before the reinstall of Windows.
