We've seen different energy modes, many new SKUs announced, recently a gaming mode, but yes, Windows 10 will be getting an Ultimate performance mode now as well. It is intended for heavy-duty machines that can’t afford to cut down on performance during processing of extensive workloads.

The new perf mode would be coming to Windows 10 Codenamed Redstone 4, the Spring Creators Update. Its Insider builds have been separated from the active development of Windows 10, reports fossbytes; Now, the insiders who earlier opted into ‘Skip Ahead’ and are still a part of it will receive Windows 10 Preview Builds under the RS_PRERELEASE branch, featuring the changes that may arrive with Redstone 5. Non-Skip Ahead users will get builds from the RS4_RELEASE branch.

 
Microsoft has released fresh Insider builds. Among the new features added is a new performance scheme called Ultimate Performance. Windows 10 Pro for Workstations users running Insider Build 17101 (rs4) or Build 17604 (rs5) can take the advantage of the new setting in Control Panel > Power Options.

As the name suggests, the power mode is designed for heavy-duty machines that can’t afford to cut down on performance during processing of extensive workloads. Microsoft’s Dona Sarkar said in the announcement post that they have been able to find areas in Windows where performance and efficiency trade-off is made and a collection of settings allows the system to adjust itself according to the user behavior, policy, and hardware.

“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.”

It goes without saying that the new power policy would require the system to consume more power while exploiting the hardware to its fullest. That’s why Ultimate Performance won’t be available on battery-powered Windows 10 PCs. Both OEM’s and users would be able to select the power plan as per their will.
