Windows ships with a hidden “Ultimate Performance” power plan that keeps components from dropping into low-power states as aggressively as the default Balanced plan. It won’t magically add frames on a desktop that already runs flat-out, but on some systems it smooths out micro-stutters caused by cores or the PCIe bus parking during light load. Here’s how to unlock it and when it actually matters.
Unlock the hidden plan
Use one command
Open PowerShell or Command Prompt as Administrator and run:
powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
Then open Control Panel → Power Options (or Settings → System → Power on some builds) and select Ultimate Performance. On desktops the plan appears immediately; on many laptops Microsoft hides it because it hurts battery life.
What it changes
The plan sets the minimum processor state high, disables aggressive core parking, and shortens the delay before ramping clocks. It also keeps PCIe Link State Power Management off, which can help GPUs respond faster to sudden load spikes.
How much does it help?
Be realistic. On a modern desktop with a good cooler, average FPS rarely moves more than a percent or two. The measurable wins show up in 1% lows and input consistency on systems that were previously letting cores idle down.
| Scenario | Typical effect on avg FPS | Effect on 1% lows / stutter |
|---|---|---|
| Desktop, high-end CPU, good cooling | 0–2% | Negligible to small |
| Desktop with core-parking stutter | 1–3% | Noticeable smoothing |
| Gaming laptop on battery | Varies | Better, but battery drops fast |
| Older CPU with slow clock ramp | 2–4% | Small improvement |
Do this instead if you want real gains
Power plans are a minor tweak. The bigger wins come from enabling your memory’s XMP/EXPO profile, keeping GPU drivers current, making sure your CPU isn’t thermal-throttling, and disabling background apps that steal CPU time. Treat Ultimate Performance as the finishing touch, not the fix.
Watch temperatures and power draw
Because the plan keeps clocks elevated during light load, idle power and heat rise slightly — often 5–15 W more at the wall. That’s harmless on a well-cooled desktop but wasteful on a laptop, where the Balanced or a custom plan is smarter.
FAQ
Is Ultimate Performance safe for my hardware?
Yes. It only prevents components from dropping into deep low-power states; it does not overclock anything or raise voltages beyond stock. Your CPU and GPU still respect their own thermal and power limits, so there’s no added risk of damage.
Why doesn’t the plan appear on my laptop?
Microsoft restricts it on many battery-powered devices to protect runtime. The duplicate-scheme command usually forces it to show up, but if it still won’t appear, your OEM may have removed it. A custom High Performance plan with minimum processor state raised gets you 90% of the benefit.
Build a custom plan if you want control
Ultimate Performance is really just a preset with certain sliders maxed. If it doesn’t appear, or you want a laptop-friendly middle ground, duplicate High Performance and edit the advanced settings yourself. The two that matter most for gaming are Minimum processor state (raise it if you get clock-ramp stutter, though 100% keeps clocks pinned and wastes power) and PCI Express Link State Power Management (set to Off to stop the GPU bus from entering low-power states between load spikes).
Don’t forget the GPU driver settings
Windows power plans only control the OS side. Your graphics driver has its own power mode — look for a “Prefer maximum performance” option in the NVIDIA or AMD control panel and set it per-game for titles that suffer from clock fluctuation. Combined with a high-minimum CPU state, this stops both the processor and graphics card from down-clocking mid-match. That said, the same warning applies: on a well-cooled desktop the gains are small and mostly show up as steadier 1% lows, not a higher average. Measure before and after with a frame-time overlay so you know whether the change actually helped your specific games rather than assuming it did.
Bottom line
Unlock Ultimate Performance with one powercfg command, switch to it on your desktop, and enjoy slightly steadier frame delivery. Just don’t expect miracles — XMP, cooling, and driver hygiene move the needle far more than any power plan ever will.
