Three often-overlooked Windows settings can deliver a tangible performance boost without spending a dime on new hardware. A recent deep-dive by How-To Geek puts startup app management, Hardware-Accelerated GPU Scheduling (HAGS), and the Best Performance power mode under the microscope, arguing that these everyday tweaks yield the most noticeable gains for everyday users. The test results reinforce what many enthusiasts have long suspected: a clean, well-configured software environment matters just as much as raw silicon.
The findings arrive at a time when Windows 11 has matured across multiple feature updates, yet the default configuration still leaves performance on the table. By adjusting these three levers, users can cut boot times, reduce background resource drain, and ensure both CPU and GPU are running at their full potential. Here’s how each setting works, the science behind the improvements, and how to configure them safely.
Startup Apps: The Silent Performance Killers
Every program that launches with Windows consumes memory, CPU cycles, and disk I/O. Over time, the list balloons—chat clients, cloud sync tools, media players, and helper utilities all register themselves to start automatically. Microsoft has improved startup impact reporting in Windows 11, but many users never check the tab in Task Manager.
Disabling non-essential startup apps reduces the time it takes for the desktop to become fully responsive after login. It also lowers idle memory usage and can prevent background processes from interfering with foreground tasks. The performance test emphasized that even modern SSDs can’t completely mask the cumulative effect of two dozen apps fighting for attention during boot.
How to Audit Startup Apps
- Open Task Manager (Ctrl+Shift+Esc) and switch to the Startup tab.
- Sort by the Startup impact column. Items listed as “High” should be the first candidates for disabling.
- Right-click any entry and select Disable. The change takes effect after the next restart.
Common culprits include Spotify, Discord, Microsoft Teams, Adobe Creative Cloud, and OneDrive. Users should ask whether an app truly needs to be running at all times. If not, disabling its startup entry won’t harm functionality—the app will still work when launched manually.
Community discussions echo this advice. On the Windows forum, users reported that slashing their startup list from 15 items down to 4 shaved nearly 12 seconds off the time until the system felt usable. Others noted that their gaming framerates became more consistent after removing background updaters that periodically spiked CPU usage.
Beyond the Task Manager
Some programs hide themselves from the standard Startup tab. Power users can dig deeper using the Autoruns tool from Microsoft Sysinternals, which exposes every autostart location including browser extensions, services, scheduled tasks, and shell extensions. For most people, though, cleaning the Task Manager list is sufficient and carries minimal risk.
Hardware-Accelerated GPU Scheduling (HAGS): Unlocking GPU Potential
Introduced in the Windows 10 May 2020 Update and carried forward into Windows 11, Hardware-Accelerated GPU Scheduling shifts the management of GPU memory and command buffers from a software-based scheduler running on the CPU to a dedicated hardware scheduler on the GPU itself. The result, in theory, is lower latency, more efficient video memory usage, and a small reduction in CPU overhead.
The How-To Geek tests found that enabling HAGS can improve frametime consistency and reduce stuttering in modern games, particularly those using DirectX 12. It also benefits GPU-intensive creative applications like Blender or DaVinci Resolve. However, results vary depending on the GPU architecture, driver version, and workload.
How to Enable HAGS
- Open Settings > System > Display.
- Scroll down and click Graphics.
- Select Change default graphics settings.
- Toggle on Hardware-accelerated GPU scheduling.
- Restart the PC.
Both Nvidia (GeForce 10 series and newer) and AMD (Radeon RX 5000 series and newer) support HAGS. Intel Arc GPUs also ship with the feature enabled by default. If the option is greyed out, the GPU driver may need updating, or the hardware may not support it.
Real-World Impact and Caveats
- Gaming: Expect modest improvements in frame pacing and slightly lower input latency. Gains are most pronounced at high refresh rates where consistent frametimes are critical.
- Content creation: GPU-accelerated rendering pipelines can see small speedups because the GPU scheduler preempts tasks more intelligently.
- Stability: A vocal contingent on forums has reported crashes or glitches with HAGS enabled, especially in older titles or when using GPU virtualization. Microsoft and GPU vendors have ironed out many early issues through driver updates, but users encountering instability after enabling HAGS should first update their graphics driver before deciding to disable the feature.
A user on the Windows forum summed it up: “HAGS gave me a 5% boost in Cyberpunk 2077 and smoothed out microstutter in Apex Legends. But I had to roll back a driver once when it started causing blue screens. It’s better now.” The consensus: test it on your own system; the gains often outweigh the potential hiccups.
Best Performance Power Mode: Letting Your Hardware Run Free
Windows 11 offers three primary power modes: Best power efficiency, Balanced, and Best performance. These govern how aggressively the operating system prioritizes energy savings versus responsiveness. On desktops, Best Performance is generally a free lunch; on laptops, it reduces battery life but significantly cuts latency in bursty workloads.
Under the hood, Best Performance relaxes many power-saving timers, permits the CPU to jump to maximum frequency more rapidly, and reduces the time the OS waits before idling components. Modern processors can ramp up clocks in milliseconds, but the default Balanced mode often introduces deliberate delays to keep thermals and power draw in check. For desktops plugged into the wall, those delays serve no real purpose.
Setting the Power Mode
- Go to Settings > System > Power & battery.
- Under Power mode, select Best performance.
Note that this is separate from the classic “Power plans” found in Control Panel. The slider in Settings interacts with the modern power throttling infrastructure introduced alongside modern standby. The old Ultimate Performance power plan can be uncovered via command line (powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61), but for most users the Settings toggle is sufficient and safer.
The performance test measured a 3–7% uplift in CPU-bound benchmarks and smoother multitasking when switching from Balanced to Best Performance. Laptop users saw similar improvements on wall power, though the impact on battery life can be substantial—expect a 10–20% reduction in runtime during light tasks, and much more under load.
Community Feedback
Forum members noted that the Best Performance mode made older systems feel snappier. “My 8th-gen Intel ultrabook was dragging in Windows 11 until I flipped the power slider. Now it’s like a new machine,” one wrote. Another cautioned laptop owners: “Use it plugged in. On battery, you’ll hear the fans spin up just opening the Start menu.”
Putting It All Together: A Three-Step Tune-Up
Individually, each tweak offers a minor bump. Combined, they compound. The original How-To Geek experiment suggests that users who perform all three adjustments see a holistic improvement in system responsiveness, from cold boot to heavy multitasking. The machine spends less time wrestling background noise and more time doing what you actually want.
Step-by-Step Checklist
- Clean your startup apps. Open Task Manager, disable everything with a “High” impact rating, then restart.
- Enable HAGS. Verify in Graphics settings, then reboot again. Ensure your GPU driver is current.
- Switch to Best Performance. Head to Power settings and move the slider—no reboot required.
This procedure takes under five minutes. There is no permanent risk; every change can be reverted instantly. Nonetheless, it’s wise to create a system restore point before tinkering, especially if you plan to toggle HAGS for the first time.
The Bigger Picture: Why These Three Matter in 2025
Microsoft continues to refine Windows 11 with features like memory integrity, virtualization-based security, and various background intelligence services. Each additional security layer exacts a tiny performance toll. Spinning up a clean installation with these three settings dialed in helps reclaim some of that overhead. As PC hardware ages, software optimizations keep it viable longer—something both businesses and home users appreciate in an era of rising component costs.
Moreover, the gap between default settings and best practice remains surprisingly wide. Even with Windows 11’s improved out-of-box experience, the default Balanced power profile and laissez-faire startup app management mean that many machines never reach their true potential. The enthusiast community and enterprise administrators have long preached these adjustments; having a respected outlet quantify the impact adds weight to the advice.
A Word of Caution
No optimization is universal. Systems with specialized configurations—digital audio workstations, machines running legacy software, or those bound by strict IT policies—may require a more nuanced approach. HAGS in particular has a spotty history with certain professional software and older APIs. Users should benchmark before and after using tools like CapFrameX, Cinebench, or PCMark to validate that the changes deliver the expected improvement without introducing regressions.
Additionally, while Best Performance removes artificial delays, it won’t magically turn a Celeron into a Core i9. Hardware limitations still apply. Think of these tweaks as removing friction rather than adding horsepower.
Looking Forward
Windows is poised for deeper integration of AI and cloud-powered features, which will likely introduce new background services and potential performance drains. The discipline of controlling what runs at startup, enabling hardware acceleration where sensible, and choosing a performance-oriented power profile will remain essential. Whether Microsoft offers a “Game Mode+” or an official tuning dashboard in a future feature update, the foundational principles endure.
For now, the message is clear: before you open your wallet for an upgrade, spend five minutes on these three settings. The results may surprise you.
