Hi,

Trying to understand about the Xcode's GPU profiling information. I have one vertex shader and I only have one draw call. When capturing a frame, I get 72us in the Summary:

And in the "GPU report" I'm getting ~6ms:

How do both metrics relate with each other and why is there so much difference between them?

Thanks

We recommend looking at the GPU Time after capturing as it's more accurate. You can also confirm the GPU Time using Instruments.
