Packaging / Building project with a Big/Little Architecture CPU

Hello! I hope this is the right section of the Forums to be posting in.

I (and some of my colleagues) have intel 12700K’s, meaning we all have 8 performance and 4 efficiency cores.

For whatever reason, whenever compiling or packaging the project, the only cores that are hit are the efficiency cores (100% utilization) - however, as a result of this our compile/package times are wayyy slower than I imagine they could be. Looking around I managed to find an answer that may help for lightmass compile (here), but unfortunately nothing for compile/package.

Has there been any news that I am somehow missing with regards to support for big-little architecture CPU’s? From what I can see there is nothing officially out about this, and the only option that seems currently available is to completely disable the E cores in the BIOS (a less than ideal option)

Thank you for any help!

Still haven’t found any news on Unreal Updating their scheduler to properly utilize the P cores during packaging ( perhaps in UE5? Still on 4.27 )

In the meantime, a seemingly “hacky” workaround was to enable “Legacy Game Mode” in the BIOS of the computer. From what I’ve seen this option may not be available in all BIOS’, but essentially it turns the scroll lock key into a Turbo. Parking the E-Cores while enabled so that no processes will be started on them ( from tests it seems that processes that were already on the E-Cores continue to run )

Hopefully this is an option for anyone else that may be running into this issue!
