@Riot FPS Drops After Recent Patch

I'd noticed my FPS dipped a bit. I used too get 300+ frames, that I capped at 144 with everything on high; except with shadows toggled off. After the patch(s) my FPS has begun stuttering and I've had to lower my settings. My GPU should be more than enough, which is why I feel like someone might've messed up with optimization during some of the updates, as my friends have told me they've experienced FPS drops as well.

Now hopefully this will be looked into.
