A bit late posting the patch notes, but we've recently released a couple updates that vastly improve the quality of online play. Check out the details:
- Sync between players is much better
- Way more accurate position tracking and scoreboard
- Close to eliminated crashes while spectating
- Retired or disconnected players show properly on the scoreboard
- AFK players are kicked after 3 minutes of inactivity
Online races should be more intense and rewarding now that these things are fixed ;)
