Happened somewhat recently? Like within the past few weeks Idr, but fps has been low, stuttering between teamfights, other people also experiencing lag and d/cs
I know in my case it makes the computer a bit hot, but the thing is that I was playing at a stable and decent FPS before this (and it was also a bit hot).
And recently in various games people seem to be getting technical issues with d/c and lag, not just me. I have everything down to lowest and I close the client.
