More 'help' on the way from Microsoft
"'As part of our effort to provide the absolute maximum performance we’re introducing a new power policy called Ultimate Performance. Windows has developed key areas where performance and efficiency tradeoffs are made in the OS. Over time, we’ve amassed a collection of settings which allow the OS to quickly tune the behavior based on user preference, policy, underlying hardware or workload.
This new policy builds on the current High-Performance policy, and it goes a step further to eliminate micro-latencies associated with fine grained power management techniques.""
In other words they are going back to high performance mode as it used to be pre Windows 10, maybe turning off super fetch too! I've been running park control free for months now that already did, I am assuming, most of this new setting. I would highly suggest all desktop users give this a try if they are having stability issues. Looks like then new Ultimate Performance mode is only coming to some flavors of Windows 10 too?
