[Client] FPS drops and whole game/pc starts to stutter
I'll try to explain as best as I can,
Quick backstory:
Started playing League again about 1 week ago, everything was fine, yesterday however while in-game suddenly my FPS dropped to around 30 but as low as 9 (Normally I get 144 capped no problem) then afterwards the whole client lagged like crazy, I could barely type a message, the whole client was super slow and when I tried another game it was pretty much unplayable since I had 30 FPS at best but mostly 10-20.
My pc is also pretty laggy/stuttering when league is open but when I close it it's chilling. At first I thought my pc was acting up but turns out its just league, I cleaned my pc, did the whole ''regedit, disk cleanup, close programs that run in the background thing. Nothing. Its still shit.
