If you’ve ever searched for Windows gaming optimizations, you’ve seen the same advice plastered everywhere: enable Hardware-Accelerated GPU Scheduling, turn on Game Mode, and set your power plan to ‘Best Performance.’ But blind adherence to AI-generated checklists can backfire — especially that last one. According to a new analysis by PC Guide, the ‘Best Performance’ power mode often delivers zero measurable gaming improvement while forcing your PC to run hotter, louder, and less efficiently.
The findings, drawn from repeated testing and a careful reading of how modern CPUs and Windows actually interact, serve as a reminder that not every toggle labeled “performance” actually delivers. In fact, the one setting that sounds like a no-brainer can be the worst change you can make.
The Three Settings Under the Microscope
PC Guide’s investigation focused on three commonly recommended tweaks that appear in AI-generated gaming guides: Hardware-Accelerated GPU Scheduling (HAGS), Game Mode, and the power plan’s “Best Performance” option. Each was evaluated for its real-world impact on gaming frame rates, stability, and system behavior.
HAGS: A Conditional Boost, Not a Magic Button
Hardware-Accelerated GPU Scheduling, found under Settings > System > Display > Graphics > Default graphics settings, offloads some of the work of scheduling graphics frames from your CPU to a dedicated hardware scheduler on your GPU. For systems with older or less powerful processors, that can slightly reduce latency and improve frame pacing in certain games. On high-end rigs with plenty of CPU headroom, the difference is often negligible — and in rare cases, it can introduce stuttering or crashes.
However, HAGS earns its place on any gaming PC for one critical reason: it’s a hard requirement for frame generation technologies like NVIDIA DLSS 3 and AMD FSR 3. If you own a recent GeForce RTX card or a Radeon RX 6000 series GPU or newer, you need HAGS enabled to use these frame-smoothing features. So even if it doesn’t bump your raw FPS, leaving it on unlocks a major performance tool in supported games.
The verdict: Enable HAGS, reboot, and test your favorite titles. If you notice stability problems, disable it — but know that you’ll lose frame generation. For most, it’s a low-risk, potentially beneficial toggle.
Game Mode: The Low-Risk Standard You Should Keep On
Windows Game Mode (Settings > Gaming > Game Mode) is far less controversial today than it was during its rocky Windows 10 debut. Its job is simple: when you launch a game, it tells Windows to prioritize the game’s processes over background tasks, suppress notifications, and reduce the chance that a sudden disk access or update check will cause a frame-time spike. It’s not a performance booster in the traditional sense — it won’t increase your GPU’s core clock — but it can smooth out gameplay on systems where background activity regularly intrudes.
For everyday gamers, Game Mode is a set-it-and-forget-it win. The only group that sometimes needs to test it is streamers using OBS. Early versions of Game Mode on Windows 10 could starve OBS of GPU resources, but Microsoft and OBS have since ironed out those conflicts. Today, OBS officially recommends leaving Game Mode on. Still, if you’re running a complex streaming setup with multiple overlays and browser sources, and you encounter dropped frames, try capping your game’s frame rate slightly below your monitor’s refresh rate before disabling Game Mode. A maxed-out GPU will cause more trouble for OBS than Game Mode ever did.
The verdict: Keep Game Mode on. It’s safe, it helps stability, and it’s designed to protect your gaming session from Windows’ own background chatter.
The Best Performance Myth: More Power, Not More Frames
Here’s where the AI advice goes off the rails. Many optimization lists urge you to switch from the default “Balanced” power plan to “Best Performance” under Settings > System > Power & battery > Power mode. The logic seems sound: if you want the best gaming performance, pick the option with “best” in the name. But that logic ignores how modern CPUs work.
Today’s Intel and AMD processors are built to boost clock speeds aggressively whenever a demanding workload — like a game — requires it. The Balanced plan doesn’t restrict them; it simply allows the chip to drop back to lower power states when you’re browsing the web or idling at the desktop. By contrast, Best Performance forces the CPU to maintain high-performance states at all times, even when all you’re doing is watching a YouTube video. That means higher power draw, more waste heat, and louder fans — with zero gaming benefit for nearly every properly configured PC.
PC Guide’s testing confirmed what seasoned enthusiasts have known for years: on a modern gaming desktop or laptop, you’re far better off leaving the power mode at Balanced. The CPU will still ramp up to its maximum boost clock the instant you launch a game; it doesn’t need a permanently elevated power state to do so. In thermally constrained laptops, forcing Best Performance can actually hurt long gaming sessions because the chip hits its temperature limit sooner and throttles back.
The verdict: Stick with Balanced. If you’re troubleshooting a specific performance problem in a CPU-heavy title, you can test Best Performance as a diagnostic step — but don’t leave it on. It will cost you in heat and noise without returning a single extra frame.
What This Means for You, by User Type
This advice plays out differently depending on how you use your PC.
Casual desktop gamer: Enable HAGS, keep Game Mode on, leave power at Balanced. You’ll get the benefit of frame generation if your hardware supports it, and your system will run quietly and efficiently when not gaming.
Laptop gamer: You have the most to lose from Best Performance. Not only does it kill battery life, it can cause thermal throttling that reduces performance in long sessions. Balanced is your friend.
Streamer or content creator: Test HAGS with your streaming software. If OBS acts up, try capping your game’s frame rate before disabling anything. Game Mode should stay on; modern Windows handles it well.
Enthusiast who loves to tweak: You can run your own benchmarks, but don’t assume that a one-click “optimization” will help. Use tools like CapFrameX or MSI Afterburner to measure 1% lows and frame times — not just average FPS — and change only one setting at a time.
How We Got Here: A Brief History of Misguided Optimizations
The “High Performance” power plan has been a staple of Windows since the Vista days. Back then, CPU power management was cruder, and locking a CPU to its highest frequency could genuinely reduce stutter in early 3D games. But processor technology has evolved tremendously. AMD’s Ryzen chips and Intel’s Core i-series now manage their own boost behavior dozens of times per second, making the old “High Performance” crutch obsolete for gaming.
Game Mode, meanwhile, had a troubled childhood. Launched with Windows 10 in 2015, it initially caused more problems than it solved, particularly for streamers using OBS. Microsoft spent years fine-tuning it, and today it’s a mature, unobtrusive feature. The demand for HAGS surged with the arrival of frame generation: NVIDIA made it a prerequisite for DLSS 3 in 2022, and AMD followed suit with FSR 3’s frame gen. That single requirement has turned HAGS from an obscure setting into a must-enable for anyone with a modern GPU.
The proliferation of AI chatbots has resurrected these old tweaks without context. They scrape decades-old forum posts and present “enable High Performance” as a timeless truth, ignoring the fact that Balanced mode has been the correct default for gaming since at least 2017.
What to Do Now: A 3-Step Setup for Smoother Windows Gaming
- Check HAGS and frame generation. Go to Settings > System > Display > Graphics > Default graphics settings. If the toggle is there, turn it on and restart. Then boot a game that supports DLSS or FSR frame generation and make sure the option is available. This alone can transform your experience in titles like Cyberpunk 2077 and Alan Wake 2.
- Confirm Game Mode is active. Open Settings > Gaming > Game Mode and ensure the switch is On. If you’re a streamer, do a test broadcast and watch for dropped frames. If problems appear, enable an in-game FPS cap 3–5 frames below your display’s maximum refresh rate before reverting Game Mode.
- Set power mode to Balanced — and forget it. Navigate to Settings > System > Power & battery > Power mode and pick Balanced. Unless you’re running a sustained non-gaming workload that benefits from constant high clock speeds (like 3D rendering), you will not notice a difference in games. Your PC will thank you with lower electric bills and quieter operation.
Outlook: The Tweak That Won’t Die
As long as search engines reward simple lists of “10 Windows tricks to boost FPS,” the Best Performance myth will endure. But the tide is turning: Microsoft’s own documentation increasingly steers users toward Balanced mode, and GPU driver updates make HAGS more stable by the month. The key takeaway is to let your hardware do what it was designed to do — boost when needed, relax when idle — and ignore the siren song of “best” in a power menu. Real gaming performance comes from smart in-game settings, fast storage, and up-to-date drivers, not from a toggle that just wastes watts.
