Spikes in 6.1 [GAMEPLAY]

Before 6.1 my computer ran League with 0 issues. I have 50mbps internet, I loaded in on the new champ select (Normal Draft Pick) the whole time my FPS would drop extremely low (at one point it was 3) and my ping would sky rocket (at one point it was over 900) it was like this the whole game. Also after about 5 minutes into the game I completely lost sound until I restarted the client. I didn't see these issues until I patched to 6.1.
