GPU visualizer (profiling tool) missing ms


I have a scene with a bunch of destructible objects that I’m using to learn how the profiling tools work.

When I enter in the console “stat unit” it tells me that the frame took 18.6ms and the gpu also took 18.6ms. So good, I know the GPU is bottleneck, however, when I bring the GPU visualizer, it tells me the frame took 6.8ms to render, see image below.

This leaves me confused, where are the 12ms that are missing?
Am I missing something?



You ever figure this out?

Anyone else know where the missing MS are?
