intel 12900k is not good choise for UE

HI there. Got new workstation with 12900ks. It has architecture with 8 big and 8 “small” enegry-efficient cores with HT.
The fact is UE is using only 8 big cores, doesnt matter what set in baseEngine.ini. Even with 20 shaderCompiler processes they working only on 8 cores.
With my one there is another new workstation with similar 12900k, and it seems to work same.
Dont know how to force using all CPU. Stress tests like linx or cpuz using all cores.
One guy has own workstation with Ryzen, and it works fine with similar amount of cores.

I got an Intel Laptop Alienware very nice but I prefer my Ryzen desktop even though the processor is a slower 3950x it is more stable.

Found that this is problem of win10, which cant handle new intel architecture.
I wrote powershell script, which takes all shaderCompile processes and manually set processor affinity. And now each process working with own core.
