I've recently just tried MBCaster to play online against other people, when I've been so used to playing the computer AIs. I connected with two people, and they were very helpful and nice about me being new to it, and walked me through on how to connect, but when I did connect, the lag was absolutely terrible. When I'm playing alone, it runs flawlessly at 60-70 FPS, but online, it dropped to single digits. I don't think it's my connection, because I can run World of Warcraft and that barely lags, the "height" of my lag on that being 200ms.
Any suggestions will be appreciated.
( By the way, I hosted the first game, and my opponent hosted the second. )
