Quantum still needs work netcode wise, if you never noticed some weird "smoke" tracks that appear from sudden around Crusader, it's people QT Jumping. The server shouldn't be transmitting that to all players really, but it shows the position in space is physical, as you can crash and get into QT Jump with other player together.
Also on News ~~ There is no 2.2 till February, clarified today. There will be however, one Hotfix for 2.1 for some issues.
Something to expect on 2.2 is certainly the PARTY System, being able to group play with friends easily stuff is really necessary as right now it's quite complicated.
Well, I do not think that rushing with the development of the new versions or small updates is the way it should be done. They have some major issues that need to be solved sooner rather than later. While a lot of players expect party system to be implemented ASAP, I would say this wait as the priority should be given to performance issues. It is not possible to play/test something if performance drops to 10-15 FPS on highest-end systems. The 100% load of the one CPU core issue should also be given a priority as it might be limiting the performance.
