I live in New Zealand and a few months ago I was trying to get Zwift to work properly but I was having issues with not seeing riders and also my graphics not being as smooth as they should be. I was told that this was likely due to the severs being used, and I was wondering if any other users, in New Zealand especially, have/are having this issue or if it has perhaps been resolved?
Suggest you check with the NZ Facebook Zwift group
