After the latest patch, I tried tapping sprint in a Plaza server (I was in West 1, with ~45 players and “200” ping (not sure if that’s correct? Steam’s Game Servers browser showed like 80-90 ping)) and it still caused very noticeable rubberbanding, comparable to how sprinting felt in the previous version of the game.
I joined a different server with less players (East 4, with ~4 players; I had ~80-100 ping according to the tab menu and ~65 according to Steam) and sprinting did actually feel significantly better there. I was only able to get noticeable rubberbanding to happen if I rapidly mashed the sprint button for like 1-2 seconds.
