Low FPS compared to before

[Denco]

Hi,

Is it just me or is the performance worse in the latest version? Granted I haven't run the sim for a while now but today I did a small experiment of ramming an earth into earth in the solar system simulation and afterwards the fps when bellow 30 to 20?

I clearly remember doing nonsense as this in previous version without such huge fps dip.

EDIT: It seem's to be caused by fragmentation parts.
