Windows 10: Why is Windows trying to use only "efficency" cores?

I have an Intel CPU with 8 hi-performance hyper-threadable cores and 4 low-performance "efficiency" cores.I'm running a CPU intensive task a 3D renderer that uses multiple cores but I find that Window 10 fully updated is assigning it to the efficiency cores and leaving the high performance cores mostly unused.See the resource monitor screen shot...This was not a problem before, I've had the computer for more than six months now. But now it is a problem. I already have my "Power Option" set to a high performance plan that should run the CPU at 100% but I'm not getting 100%. I used to get

Overclocking / Undervolting guide for Vega 56 or 64?

Here's a quick laundry list:

List of software to use for overclocking and testing
Examples:
Wattman (and how to find and use it, like an overview, including profiles)
Unigine Valley or Heaven (use this for quick testing while changing settings in Wattman and checking for stability / artifacts) ...just suggesting this
How to monitor cores / mem speeds and temps during testing (I've seen screen overlays, and others using GPUz)

Intel Gives Core i3 and Core i5 Dual-Core Processors K0 Stepping Update

Intel is giving some existing 32 nm "Clarkdale" based Core i3 and Core i5 processors an update. The processors will transition to the new K0 stepping from the existing C2 stepping. The parts that will be made on the K0 silicon are Core i3 models 530 (new sSPEC: SLBX7), 540 (new sSPEC: SLBTD) and Core i5 models 650 (new sSPEC: SLBTJ), 660/661 (SLBTK/SLBTB), 670 (SLBTL). Newer and upcoming models such as the i3-550, i3-560, i5-665K, and i5-680 are already being built on the K0 stepping die. Motherboards will require a BIOS update to support the new K0 stepping processors.

The K0 stepping change includes the following highlights:

• New S-spec and MM numbers for the converting products
• Extended CPUID will change from 0x00020652 to 0x00020655
• Host RevID will change from 0x12 to 0x18
• K0 stepping package is pin compatible with C2 stepping package
• Adds Processor Context ID (PCID) support

The revised older SKUs that are built on K0 stepping will be market-available by October 16.
