In my last couple of rides since the latest version update I’m sure Zwift has become smoother/faster/slicker.
Running on my Surface laptop I used to get 10-12 fps but now I can get 15+
In addition I’m not experiencing other riders flickering, disappearing or suddenly passing me then dropping back and passing again anywhere near as much as I used to.
Looks like possibly they’ve improved things server-side as well as client-side.
Big thumbs up.
