I'm experiencing a major performance drop in-game, to the point where I can't even teamfight. I'm not sure what causes the issue. But it's been happening since the latest patch.
Before patch avg. FPS: 100 (Capped to 100)
After patch avg. 50 (goes down to 20-30 in teamfights)
My computer is perfectly fine, it's a (somewhat) fresh install and I haven't had problems before the patch.
Anyone else experiencing this?
