DCS:W procces is running in efficiency mode, causing extreme frame stuttering.

Yes, it should be applied to Win 10 and 11 according to:

Overview about power and performance tuning for the Windows Server | Microsoft Learn

For me, I have both CPMAXCORES and CPMINCORES to be decimal 100.

To find out the registry UUIDs for two GUIDs, CPMAXCORES and CPMINCORES :

powercfg -qh

for these two keywords.

EDIT: Bitsum ParkControl can verify the core parking/unparking.

Is any of this needed for AMD processors like the 9800x3d and similar? I have never seen core parking messages in my log file. I'd be more interested on how to manage the peripheral programs we use along with dcs. Ive tried PL with mixed results.

No. Hybrid cores are only issue of Intel CPU's.

Ryzen 9000 series may have exactly opposite problem with core parking than Intel has. AMD Ryzen 9000 series intentionally parks the cores so that the game runs on only single chiplet with 3D V-Cache, which is correct because it extremely reduces latency. The problem is that if you don't set up the system correctly, it doesn't work as it should. The cores don't park when they should. I recommend watching this video which explains the AMD problem in depth and gives solution how to fix that:

Well. I've found the core parking have been somehow overriden. After reset power profiles it looks like the issue has gone. But I am not sure right now. I need to observe it for longer time to be sure.

Was your issue due to the core parking?
