The CPU performance delivered by Predator G9-791 using i7-6700HQ makes it clear that the processor is under-performing, I have attached details of the performance.
Definitely, somewhere something is missing in ACER Predator G9-791 BIOS, firmware, driver, etc. It's a humble request to ACER, to kindly look into, as it certainly requires attention.
Issue
==============
I know ACER Predator G9-791 is a gaming machine and the hardware specs qualifies equally to run Virtual Machines.
(Iam NOT talking about CAD, MAYA or any 3D rendering software which uses Nvidia Quadro)
Issue is, the CPU utilization is constantly 100% when 5 Virtual Machines are running at the same time.
I replaced my old MSI GT70 running i7-3610QM with Acer Predator G9-791 and to my surprize they both perform almost the same.
I made 3 comparisons (MSI GT70, Lenovo P50 and ASUS G752VY) details provided below:
