The new beta patch solves the annoying ground stutter and that's good
No more hiccups when the single Blenheim takes off. Overall, much smoother and more enjoyable than all previous beta patches. It seems they have found and fixed the large bugs in their new game engine. Still not as smooth as RoF, but nevertheless.
A bit of dissapointment is the fact all other bugs (commands, AI, mirror..) are still there. There has been very little progress here and this, combined with releasing the SDK, they need to fix and improve asap.
