I'm currently immo 1 from solo queing, I'm bottom fragging alot of the time and I don't really seem to know the reason. I tried to rewatch my gameplay many times but don't really see consistent mistakes that I'm making, and my aim is a hit...

how do I yoru ult with shorty and when should I. Whenever I yoru ult my enemies literally kill me before I can pull out a shorty without ever even being in the visibility range. pls help

I have bad fps, stutters, and horrible hitreg only in competitive, spike, dm and casuals are fine? Is this anticheat ruining my game or what? Does someone know how to fix?
