constant crashes and performance issues since league start

this league is genuinely unplayable
constant crashes, you keep telling us you've fixed ctds and what not but the state of the game is the same since league start. so what is going on?
performance has dropped off a cliff too, generally, can't do ultimatums anymore. vfos crashes my game every few maps, cpu usage is crazy high even when there's nothing going on
new pinnacles give you that shader load fps drop and choppiness no matter how many times you run them
like what is going on GGG, can we get a proper explanation for the issues at hand? and what you're doing to dircumvent them?
