It's very difficult to even join a game. It loads for 30 seconds - 1 minute, and then usually text appears, it says "join failed: session no longer available" or something along those lines. If you do manage to connect with someone it's generally very laggy, since it's GGPO this results in frames skipping...in other words the characters teleport all over the screen.

I hope CAPCOM sees this issue..

My ISP has a ping time of about 40-50ms. That's not that great and can result in bad online gaming. But in SSF4 I get to choose my connections. With 3s it's a crapshoot and often I get very poor connections. I maybe get a stable (yellow) connection about 60% of the time.

That's the only issue I have. Region selection would go a long way to improving this.
