Wow! This is absolutely fantastic, I can run my two 18mill ships battling each other at 4x speed now.... While it does slow it down, I still believe it's faster than 2x. Previously I could only run it without too many problems at 1/2x speed, and once the battle was underway (lots of parts and missiles) 1/4x, and even then it would be choppy and slow.
This update is absolutely fantastic, thank you 🙂
EDIT: Ok after further testing I think the slowed down speed actually averages at about 1x speed, which is still fantastic though for such a huge battle!
