Windows 11 Gaming Benchmarks Confirm Near-Identical Average FPS, But Deep Minimum-Frame Drops Raise Concerns

The numbers don't lie: upgrading from Windows 10 to Windows 11 yields virtually identical average frame rates in the latest games. But a deeper look at the data reveals a disturbing trend—minimum frames per second can plummet by over 50% in some titles, introducing jarring stutters that ruin the experience. As the October 2025 end-of-support deadline for Windows 10 looms, gamers face a tough choice between staying on a secure, supported platform and risking occasional but severe performance regressions.

Testing Methodology and Hardware

A fresh round of hands-on testing, detailed in a report by Glass Almanac, put the two operating systems head-to-head on a high-end gaming rig. The test bench included an AMD Ryzen 7 9800X3D processor, an NVIDIA GeForce RTX 5070 Ti graphics card, and 32 GB of DDR5 RAM—hardware that represents the pinnacle of current gaming performance. Seven demanding titles were benchmarked under identical in-game settings, first on a clean Windows 10 installation and then again on a freshly installed Windows 11 version 24H2. The focus was on both average FPS (the headline number) and the often-overlooked 1% and 0.1% lows, which directly affect perceived smoothness.

Average FPS: A Draw Across the Board

Across the test suite, average frame rates were practically indistinguishable. Red Dead Redemption 2 clocked 135.8 FPS on Windows 10 versus 135.9 FPS on Windows 11. Cyberpunk 2077 posted 86.9 FPS and 88.1 FPS, respectively. Even in titles where Windows 11 pulled slightly ahead, the gap never exceeded 2%—well within normal benchmark noise. Anno 1800 dipped from 151.4 FPS to 147.9 FPS, while Grand Theft Auto V Enhanced moved from 106.3 FPS to 104.4 FPS. These results mirror findings from multiple independent testers and confirm a clear message: for the majority of today's games, moving to Windows 11 will not alter your average framerate in any meaningful way.

The Problem: Minimum FPS and Micro-Stutter

Where Windows 11 stumbles is at the low end of the frame-time distribution. The 1% and 0.1% lows—the frames that cause visible stutters when they dip—tell a different story. Black Myth: Wukong, a notoriously demanding title, saw its minimum FPS collapse from 71 to just 29 after the upgrade. GTA V Enhanced’s minimum plummeted from 88.9 FPS to 51.6 FPS. A single frame drop from 70+ to below 30 is instantly felt and can break immersion, especially in competitive or fast-paced scenes. Other titles tested in community benchmarks, such as Doom and Far Cry 6, exhibited similar but less dramatic regressions. These are not universal; some games even showed improved minimums on Windows 11. But the inconsistent nature of the issue is precisely what makes it dangerous for gamers expecting a seamless transition.

What’s Causing the Drops?

No single culprit has been definitively identified. The evidence points to a combination of factors, each plausible but difficult to isolate:

• Driver interactions: New OS builds can alter how GPU drivers behave. Minor timing differences or changes in the driver stack might expose vulnerabilities in certain game engines. A clean driver installation after upgrading sometimes resolves the issue, but not always.
• CPU scheduler changes: Windows 11’s kernel scheduler handles threads differently, especially on processors with hybrid architectures or 3D V-Cache (like the Ryzen 7 9800X3D used in testing). Some Ryzen users report micro-stutters after specific Windows 11 updates, suggesting scheduler quirks.
• Background services and telemetry: Windows 11 runs a broader set of default services and housekeeping tasks. A background process waking a core at the wrong moment can cause a frame-time spike, particularly in CPU-bound scenarios.
• Hardware-accelerated features: Toggles like Hardware-Accelerated GPU Scheduling (HAGS) and Game Mode can have game-specific, unpredictable effects. Combined with DLSS Frame Generation or DirectStorage, these features may occasionally clash with the OS.
• Game engine sensitivity: Some titles are pathologically sensitive to small I/O or scheduling hiccups. Shader compilation stutters, texture streaming bursts, or ray tracing spikes can be magnified by even tiny OS differences.

Community troubleshooting threads reflect this complexity. A fix that works for one user—a driver rollback, a BIOS update, disabling an overlay—may fail for another. The sporadic nature of the regressions underscores why blanket statements about Windows 11’s gaming prowess are premature.

Community Reactions and the Looming Deadline

On enthusiast forums, the conversation is split. Many users report a smooth upgrade with zero issues, while others post frame-time graphs showing deep valleys absent under Windows 10. The common thread: those who measure only average FPS often declare parity; those who monitor 1% lows or play competitively notice the stutters. With Windows 10 support ending on October 14, 2025, and Microsoft offering an Extended Security Updates (ESU) program as a bridge, the pressure to decide is mounting.

The Clock Is Ticking: Windows 10 End of Support and ESU

After October 14, 2025, Windows 10 will no longer receive routine security patches unless users enroll in the ESU program. Microsoft has confirmed a consumer-friendly ESU path: a free first year for users who sync their PC to a Microsoft account cloud service, followed by subsequent years at around $30 per year. Businesses and organizations have separate licensing tracks. This effectively buys time—a safety net for gamers who want to wait for driver maturity or OS refinements before migrating. However, it is explicitly a temporary measure, not a long-term solution.

Should You Upgrade? A Practical Guide

Given the data and the deadline, here are clear paths forward:

Upgrade now if:
- You want the latest features (DirectStorage improvements, Auto HDR refinements) and long-term OS support.
- Your hardware is fully compatible, and you are willing to troubleshoot minor hiccups.
- Security and staying on a supported platform outweigh the risk of occasional stutters.

Wait and use ESU if:
- You cannot afford any risk of micro-stutter, especially for competitive gaming.
- Your primary titles appear in the list of affected games, and you lack a secondary system for testing.
- You believe future Windows 11 updates and driver fixes will iron out the issues.

Before any migration, create a full system image backup. Test Windows 11 on a spare drive or partition, focusing on the exact games and scenes that matter to you. Monitor frame-time graphs, not just averages, and be prepared to roll back if your experience degrades.

Optimizing Windows 11 for Smooth Gameplay

If you do upgrade, these steps may mitigate or eliminate the minimum-FPS regressions:

1. Perform a clean GPU driver installation using Display Driver Uninstaller (DDU) in safe mode, then install the latest WHQL driver from NVIDIA or AMD.
2. Update motherboard BIOS and chipset drivers to the latest vendor releases.
3. Temporarily disable overlays and peripheral software (Steam overlay, SteelSeries GG, Razer Synapse, etc.) during testing.
4. Experiment with Hardware-Accelerated GPU Scheduling and Game Mode—try both on and off to see which yields smoother frame times in your titles.
5. Toggle frame generation and DLSS features individually; some users report that turning off DLSS Frame Generation reduces stutters in certain games.
6. Use monitoring tools like MSI Afterburner or CapFrameX to capture 1%/0.1% lows and frame-time graphs, not just averages.
7. Keep Windows and drivers updated, but test major updates on a secondary boot environment before committing to your main gaming installation.

The Bottom Line

For most PC gamers, the move to Windows 11 is not the performance disaster some feared—nor the panacea others hoped for. Average FPS stays rock-steady, confirming that your GPU’s raw power translates nearly identically across both operating systems. The real story lies in the outliers: severe minimum-FPS drops that turn smooth gameplay into a stuttering mess for a subset of titles and hardware configurations. These regressions are not hallucinations; they have been reproduced in controlled tests and echoed in community feedback. Yet they remain inconsistent, suggesting that driver updates, scheduler tweaks, and game patches may gradually close the gap.

As the October 2025 deadline approaches, gamers have more control than ever: they can test thoroughly, leverage the ESU program as a buffer, and apply targeted optimizations. The safest path is deliberate, well-instrumented upgrade planning—back up your system, benchmark your favorite games before and after, and let the data guide your choice. Performance parity is here; the challenge is ensuring that parity extends all the way down to the frames that matter most.
