[Client] When I try to engage specifically an enemy champion, I get very bad lag.

Patch 5.21

At first I thought it was just me. Then the first game it happened, my Support picked up on it as well. Saying when they go to fight someone, it starts lagging horribly.

I thought maybe it was just my wifi. But if it was other people wouldn't be feeling it as well.

The Client on its own has been slower than usual as well.

Whats REALLY freaky is that my ping is only 20 and my FPS is 24 or 30.

Has anyone else been experincig this?

Are people doing something to cause this.
