New engine seems reasonably playable to me, barring a few bugs:
- rectors dont work (they perform one action, then they can no longer build anything or build assist)
- freakers - same issue
- you can not /take someone
- fixed wing bombers cannot reload bombs, neither at factory nor at repair pad
Engine seems to load faster (haven't tried big or speedmetal maps yet)
There is a lot of in chat spam about some widgets not working properly, but dont ask me which ones.
Most stuff seems to be working just fine, i.e. com and unit morphing, jump commands, giving factories fight orders (but don't do that on a cloaky or jumper factory and have it produce constructors, those will be useless after their first build-assist).
There are some people that cannot really play the game, they have difficulty loading or their graphics drops to 1fps, why I have no idea (Akantor being an example).
So, near unplayable is a very big and unnecessary word for something that is in 'testing'.
