I live in South Florida and even though I connect to another player from South Florida gameplay feel very slow. Not lag, just slow. It happens once in a while when I connect to anyone international as well.
This has only happened in Top Spin 4 and when it does, It’s a very weird feeling, it’s like my opponent and I should be talking to each other in slow motion.
When this happens, I usually check to make sure my network is clear and no data is being transferred.
