Windows 11 Ultimate Performance: Turn It On?
Yes, you should turn on the Ultimate Performance power plan in Windows 11 if you are on a desktop PC that is plugged in and you need to squeeze out every bit of responsiveness for demanding tasks like 3D rendering, video editing, or high-end gaming. However, for most laptop users and everyday tasks, the default Balanced plan is better because Ultimate Performance disables aggressive power-saving features, which can drain your battery and generate extra heat.
What Is the Ultimate Performance Power Plan?
Microsoft introduced the Ultimate Performance power plan in Windows 10 April 2018 Update and carried it over to Windows 11. It is a hidden power plan that is not listed in the standard Power Options control panel. Unlike the Balanced or High Performance plans, Ultimate Performance removes micro-latencies associated with power management. It tells the operating system to never throttle the CPU, never put hard drives to sleep, and never reduce the speed of connected devices. The plan is designed for workstations that run heavy, sustained workloads where a tiny delay can cost time or money.
It is important to understand that Ultimate Performance is not a magic overclocking tool. It does not increase your processor’s maximum clock speed or improve your graphics card’s core clock. What it does is remove the small pauses that occur when the OS decides to lower the CPU frequency during brief idle moments. For a short burst of activity, like opening a web browser, you will not notice any difference. For a 30-minute video render, the effect is also minimal because the CPU is already at full load. The benefit appears in workloads with many short, unpredictable bursts, such as compiling code or running a complex spreadsheet macro.
How to Enable Ultimate Performance in Windows 11
By default, the plan is hidden. You can reveal it with a single command in an elevated PowerShell or Command Prompt window.
- Press Windows + X and select Terminal (Admin) or Windows PowerShell (Admin).
- Type or paste the following command and press Enter:
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 - You will see a message like: Power Scheme GUID: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx (Ultimate Performance)
- Close the terminal, open Control Panel > Power Options, and you will now see Ultimate Performance listed. Select it.
If you want to revert to the default, just select Balanced in the same window. You can also remove the plan later with powercfg -delete followed by the GUID, but that is rarely necessary.
What Actually Changes When You Turn It On?
To understand the plan, you need to look at the underlying settings. The Ultimate Performance scheme sets several key policies:
- Processor minimum and maximum state is set to 100%. The CPU never drops below its base clock, even when idle.
- Hard disk turn off after is set to 0 (never). The drive spins constantly.
- USB selective suspend is disabled, so USB devices never enter a low-power state.
- PCI Express link state power management is off, meaning expansion cards (like GPUs and NVMe drives) never enter a low-power link state.
- Sleep and hibernate are effectively disabled; the PC stays on until you turn it off.
In contrast, the Balanced plan allows the CPU to drop to 5% or 0% when idle, spins down hard drives after 10-20 minutes, and suspends USB ports. These power-saving features do not cause noticeable lag on modern hardware because the wake-up time is measured in milliseconds. The only time you might feel the difference is in latency-sensitive audio recording or high-frequency trading, where a single millisecond of jitter can be a problem.
Should You Use It? Pros and Cons
The right choice depends on your hardware and usage pattern. Here is a breakdown of the real trade-offs.
- Desktop PC, plugged in, heavy workloads (video editing, 3D rendering, scientific computing): Yes, turn it on. The constant high clock speed prevents any micro-stutter in previews or simulations. The extra power draw is negligible on a desktop.
- Laptop, even if plugged in most of the time: No, unless you are doing a specific render or compile. The plan prevents the CPU from entering deep idle states, which increases heat and fan noise. It also shortens battery life when you unplug.
- Gaming: Usually not worth it. Games are mostly GPU-bound, and the GPU has its own power management. The CPU will already boost to maximum when needed. The only exception is competitive esports titles that are CPU-bound and run at very high frame rates (200+ FPS), where you might see slightly more consistent frame times.
- Everyday browsing, office work, streaming: No. You will not notice any speed difference, and you will waste electricity and generate unnecessary heat.
Common Misconceptions and Problems
One common misconception is that Ultimate Performance will increase your CPU’s maximum clock speed. It does not. It only prevents the CPU from dropping to a lower speed when idle. If your CPU is already boosting to 5 GHz under load, it will still boost to 5 GHz under the Balanced plan. The difference is that under Balanced, when the load drops for 0.5 seconds, the CPU might drop to 800 MHz and then boost back up. Under Ultimate, it stays at 5 GHz. That can actually increase power consumption and heat for no real benefit in most scenarios.
A problem you might run into is that the plan does not appear after you run the command. This can happen if you have a laptop with a battery. Microsoft intentionally hides the plan on laptops because it would drain the battery too quickly. The command still works, but the plan may not show up in the list. A workaround is to switch to the High Performance plan first, then run the command, but even then, Windows may revert to Balanced after a reboot. In that case, you can create a custom power plan with the same settings manually, or just accept that it is not meant for portable devices.
Another issue is that the plan disables sleep and hibernation. If you walk away from your PC, it will stay on indefinitely. That can be a security risk if you do not have a screensaver with a password, and it wastes energy. You can re-enable sleep by editing the plan settings, but that partially defeats the purpose.
Alternatives to Ultimate Performance
If you want better performance without the downsides, consider these alternatives:
- High Performance plan: This is a built-in plan that keeps the CPU at a high minimum state (usually 100% when plugged in) but still allows the hard drive to sleep. It is a good middle ground for desktops.
- Balanced plan with processor minimum state set to 100%: You can edit the Balanced plan’s advanced settings and set the minimum processor state to 100%. This gives you the same CPU behavior as Ultimate Performance but keeps other power-saving features (like USB suspend) intact.
- Windows 11’s built-in Game Mode: This does not change power plans but prioritizes background processes for gaming. It is useful for gamers who want to keep the Balanced plan.
- Hardware-specific software: Many motherboards and laptops come with their own power management software (e.g., from the manufacturer) that can optimize performance. These are often better tuned than the generic Windows plan.
How to Read the Results and Verify It Works
After enabling the plan, you can verify it is active by opening Control Panel > Power Options and checking that the radio button next to Ultimate Performance is selected. To see real-time CPU frequency, open Task Manager (Ctrl+Shift+Esc) and go to the Performance tab. Under the CPU section, you will see the current speed. With Ultimate Performance, the speed should stay near the base clock even when idle. Under Balanced, it will fluctuate.
For a more precise measurement, you can use the built-in powercfg /energy command to generate a report that shows power management issues. However, that report is technical and not necessary for most users. The simplest test is to run your typical heavy workload (e.g., a video export) and compare the time it takes with Balanced vs. Ultimate Performance. In most cases, the difference will be less than 2-3%, which is within the margin of error. If you see a bigger difference, it might be due to other factors like thermal throttling.
Frequently Asked Questions
Does Ultimate Performance damage my CPU?
No. It keeps the CPU at a higher clock speed, which generates more heat, but as long as your cooling system is adequate and the temperature stays below the manufacturer’s maximum (usually around 95-100°C for modern CPUs), it is safe. The plan does not increase voltage beyond the default boost behavior.
Will Ultimate Performance improve gaming FPS?
In most games, no. Games are typically GPU-bound, and the GPU is already at full load. You might see a tiny improvement in CPU-bound games with very high frame rates, but the difference is often less than 1-2 FPS. It is not worth the extra heat and power draw for gaming alone.
Why is Ultimate Performance not showing up in my power options?
It is hidden by default. You need to run the command powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61 in an elevated terminal first. If it still does not appear, you may be on a laptop, where Microsoft hides it by design.
Can I use Ultimate Performance on a laptop?
You can force it, but it is not recommended. It will drain the battery quickly, generate extra heat, and may cause the fans to run constantly. If you need performance on a laptop, plug it in and use the High Performance plan instead.
Does Ultimate Performance affect battery life?
Yes, significantly. Because the CPU never drops to low power states and the hard drive never sleeps, the battery will drain much faster. If you are on battery, always switch back to Balanced.
How do I turn it off and go back to Balanced?
Simply open Control Panel > Power Options and select the Balanced plan. You do not need to delete the Ultimate Performance plan. If you want to remove it entirely, you can use powercfg -delete followed by the GUID, but that is optional.
