What happened to the performance?

Ever since the 6.3 update I've played about 15 games or so and before that everything was fine. Since the update loading from the log-in screen to the main menu, main menu to games, and games to the after match lobby, everything has been so damn slow. I know its nothing to do with my rig because this is the only app that i have this issue with. I would really like to know whats going on or if riot has any plans to fix this. The loading screens are taking almost as long as Bloodborne loading screens pre patch. performance Another thing that's been happening is random frame drops. I play the game (when uncapped) at anywhere from 80 to 120 frames and I have it capped at 60 because i usually do other things on my second monitor like watch videos or tv shows. These recent games I've been playing I have not had any programs open other than league and I will randomly drop from 60 frames to 0/5 frames every 30 seconds or so.

I know this has nothing to do with my system or rig so it has to be something with league of legends its self. As stated before I run other programs flawlessly (ex. WoW CSGO Dragon Age) and i really just want this fixed so I can actually play this game.
