[4.7.1] - Engine appears to causing a lot of CPU Stalls

Hi

I’ve tried to reproduce your problem with testing the same project from 4.6.1 verses 4.7.2 with almost the opposite results shown here (The 4.7.2 -2nd image- is about the same speed at half % CPU usage):

This leads me to ask, are you still experiencing lag with a brand new project in 4.7.2?
