I haven't had any additional problems in connection lag with players from other continents. Sure we've had the usual problems, whether it's the person's home WiFi glitch, or someone has an old computer or a slow internet service, or the times when Roll20 has a hiccup. Nothing that seemed attributable to distances around the Earth. I've played with people from as-far-away as I could point on the opposite side of the globe, and regularly have players separated by oceans from 2-3 continents in a game. In my experience I would say (surprisingly perhaps) no detectable added latency at all. We converse and chat and play in real time. Thinking about it now, it is really such an honor to meet gamers from other countries and play creative games with talking, interaction on here, people who I otherwise probably wouldn't meet or get to know them in extended conversations week to week like this.
