With New Patches Come New Bugs

Wondering if this is happening to other players? First of all since the server change I'm not a fan, higher pings and more lag. However, I've moved on from that and dealing with it, but now after a game of playing or even less than a game my FPS takes a dive from 40-60 down to 10-15..

This obviously makes it terribly impossible to enjoy much less play, is this happening to other players? Before all the snarky genius comments pop in, yes i have everything turned down to nearly the lowest quality setting.

Also play on a MAC which from the start of my short LoL experience has been terrible, i get it but i'm not getting a new cpu/laptop for LoL.

Hoping to get a fix!

Thanks!
