Yeah this patch is a nightmare my guy. Last night I realized that out of my last ten games, I've had crippling lag in 9 of them and the one game where I was doing fine my duo disconnected over ten times throughout the course of fifteen minutes. He was level 6 with 20 cs when they killed our nexus. Eventually I screwed around with some settings and managed to make the lag A BIT better but still not perfect by any means. I had two decent games before it started lagging again. One game I got into and was immediately on about 600 ping, then when I restarted my client I got the frozen load wheel glitch and by the time I finally realized it my team had already remade.
Apparently turning off the "Automatically connect to this wifi network" option on your computer can help, and also going into the features of windows and disabling their xbox Live game service which likes to turn itself on without your input- As if your computer is an xbox.
I'm incredibly disappointed in this new client that riot forced on us. It's really bad, and the fact that none of them want to talk about it and they're acting really sluggishly to fix it makes me assume what people have been thinking for weeks- That it's filled with tencent's spyware, and it's not going to get better.
Yay China.
