[CLIENT] DJ Sona, Massive FPS Drop

Right when I start the game with DJ Sona, my FPS drops between 1 - 20. I usually play on a uncapped FPS setting and have a average FPS rate of 55 - 60 on all max settings.

I haven't played Sona since last season and now when i play her for the first time preseason. This happens =/

Please help me Riot! Thank you!
