Howdy, your friendly neighborhood interweb Chokai here. I remember reading in another thread this, but I haven't seen it posted. So please do this. Use this to run the game:
Do NOT use GameCenter for anything but updates. I finally went to my files and did this. Low and behold, my Ping went from random 130-180 oscillations, my packet loss no longer has random 30%, 50%, and 100% episodes, and the frame rate somehow improved.
I have no idea how any of that changed, but it did. Suddenly, I get why people like the I-211 now that I can connect with it. Suddenly I remember why Derp guns are fun. Because they are possible to connect with now!
