Jin and I had a set last night that had crazy input lag (I though GGPO was suppose to eliminate input lag >:(). Granted he is from around Maryland (I think) and I am from Seattle. I have a hardwired connection too.
I have been getting really bad connections from the east coast. West coast seems smooth as butter but anyone from Colorado or east is pretty brutal.
I’ve had some mixed experience with the online in this game. I have both versions and on PS3 I usually find higher ping matches, but when I get a decent connection it feels silky smooth and I’ve never experienced slow down in matches however on 360 I usually get lower ping matches, but slow down occurs occassionally as you can see between the set DevilJin and I ran.
BTW you spelled my name with an “s” at the end in your vid captions, DJ. 
I was hungary when I made the video.
That sounds like the experience I had in 3S OE…except in 3S OE a green ping was solid no problems instead of slowdown 70 percent of the people I played.
Having this issue too. Weird slowmo mode, no teleports even when GGPO settings are high sigh.
*Edit - Not happening with everyone mind you, just most people.
