Alongside the features and changes included with the Windows 10 April 2018 Update (version 1803), Microsoft also introduced the Ultimate Performance power plan to provide the absolute maximum performance for Windows 10.
The Ultimate Performance scheme is a new policy based on the current High Performance policy, and it goes further with tweaks to eliminate micro-latencies associated with fine grained power management techniques. In addition, it provides lower stuttering, and of course, it maximizes performance.
The only caveat is that it’s a power scheme reserved only for the “Workstations” edition of Windows 10. However, if you want to give it a try to see if it offers any benefits on your computer, you can enable the Ultimate Performance mode on any edition of Windows 10 version 1803 using the PowerCFG command tool.
In this guide, you’ll learn the steps to enable the Ultimate Performance power plan on Windows 10.
How to enable Windows 10 Ultimate Performance using PowerShell
If you want to enable the Ultimate Performance power plan on your device and you’re not running Windows 10 Pro for Workstations, use these steps.
Search for PowerShell, right-click the top result, and select Run as administrator.
Type the following command to enable the Ultimate Performance in Control Panel and press Enter:
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
Restart your computer.
Open Control Panel.
Click on Hardware and Sound.
Click on Power Options.
Under additional plans, select the Ultimate Performance option.
After completing the steps, you can test the new power plans to see if you notice improvements in performance when working with demanding workloads on your high-end computer.
The Ultimate Performance power policy is currently not available when running a device on battery.
