A new feature for Windows 10 Pro for Workstations is the "Ultimate Performance", a new power scheme that will include special power management features to ensure performance is as best as a system will allow.
Demanding workloads on workstations always desire more performance. Windows has developed key areas where performance and efficiency tradeoffs are made in the OS. Over time, Microsoft has 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. The Ultimate Performance Power plan is selectable either by an OEM on new systems or selectable by a user. To do so, you can go to Control Panel and navigate to Power Options under Hardware and Sound (you can also "run" Powercfg.cpl). Just like other power policies in Windows, the contents of the Ultimate Performance policy can be customized.
Microsoft says that as the power scheme is geared towards reducing micro-latencies it may directly impact hardware; and consume more power than the default balanced plan. The Ultimate Performance power policy is currently not available on battery powered systems.
The new mode will be available in the next Windows 10 update, expected to be released in March or April.
Microsoft first introduced Windows 10 Pro for Workstations last year, and it's primarily designed for server grade PC hardware and power users.
