Profiler GPU usage total is less than 100%?

Performance & Profiling Profiling Tools

I’m learning my way around the Unity profiler for the first time, and I came across an odd problem:

In this screenshot, the GPU is supposedly taking ~13ms to render the frame, but only around 9ms are shown in the hierarchy. The same goes for the other viewing options (timeline and raw hierarchy).

Why doesn’t this total up to 100%?

Hey _eternal, did you ever figure this out?

I too have the same issue. It seems that “Other” take up the rest of the time. In fact in my case, “Other” takes up about 70% of the time.

What is “Other” and how can we optimize it? Can someone please shed some light on this?
