Windows 11 includes an optional OS graphics feature called Hardware Accelerated GPU Scheduling (abbreviated as HAGS), and this performance analysis will showcase gaming using the Gigabyte AORUS RTX 3080 MASTER. We will compare the performance of 26 PC games with HAGS on versus HAGS off using our latest recommended GeForce Game Ready driver, 512.15, and Windows 11 version 21H2.

The Windows 10 May 2020 Update (version 20H1) added this feature, and we tested it using this Windows version in November 2020. Unfortunately, we saw that the HAGS feature led to performance inconsistencies on Windows 10. That made us not recommend it for general use at the time. We’re now revisiting HAGS performance using the latest Windows 11 public build to see if it is finally worth it.

You can enable HAGS through the Windows 11 “Default graphics settings” menu as long as you satisfy its requirements: Windows 10 v20H1 or newer, a supported GPU (Pascal onwards from NVIDIA, and RX 5600 onwards from AMD), and HAGS compatible GPU drivers.

This time, our testing platform is a recent install of Windows 11 64-bit Pro Edition, an i9-12900K with stock clocks, an ASUS PRIME Z690-P D4 motherboard, and 32GB of T-FORCE XTREEM ARGB WHITE DDR4 3600MHz. The games tested, settings, hardware, GeForce drivers, and Windows 11 build are identical except for the HAGS’ states we compare (on vs. off).

Before offering the performance data and charts of each different analysis scenario, it’s important to describe both the hardware and software configuration used in our testing, as well as the analysis methodology.

• Consecutive runs until detecting 3 valid runs (no outliers) that can be aggregated by CapFrameX using the following method:
  • ‘Aggregate excluding outliers’:
    • Outlier metric: Third, P0.2 (0.2% FPS percentile).
    • Outlier percentage: 3% (the % the FPS of an entry can differ from the median of all entries before counting as an outlier).
• We compare and value the results and aggregated records in terms of percentages of gain/loss, by setting the following thresholds to consider a certain % value as significant (not within the margin of error) for our benchmarking purposes:
  • Score/FPS Avg > 3% when valuing hybrid and non-synthetic benchmarks;
  • FPS Avg > 3% when evaluating raw performance;
  • P1/P0.2 > 3% when evaluating frame time consistency; after applying our custom formula

The Performance Summary Charts with 26 Games

Below are the summary charts of 26 games used to compare the games’ performance changes with HAGS enabled and disabled using the AORUS RTX 3080 MASTER.

You can see the list of graphics settings on the charts, and we run each built-in or custom game benchmark’s sequence at 2560×1440, except for Days Gone, Far Cry New Dawn, and Far Cry 6 tested at 3840×2160 resolution. You may click on each chart to open a pop-up for the best viewing.

Results give average framerates and higher is better. We display the low FPS percentiles (P1 and P0.2) below the corresponding averages. We use CapFrameX to record frametimes over time and to visualize and convert them into their corresponding average FPS and P1 and P0.2 FPS percentiles values.

There are also columns showing percentages of gain/loss in both raw performance (average FPS) and, when applicable, in frametimes consistency or stability between the different states of the HAGS feature. We applied the following custom formula to calculate the stability gains or losses:

{[(LowPercentileFPS_2 / AvgFPS_2) / (LowPercentileFPS_1 / AvgFPS_1)] – 1} x 100

We mark significant performance changes (higher than 3%) in bold and use purple for the significant improvements or orange font for regressions.

Hardware Accelerated GPU Scheduling Performance Charts ( On vs. Off)

Notes on Windows 11 Hardware Accelerated GPU Scheduling performance (On vs. Off)

For the game benchmarks, although most games show no significant performance differences with HAGS enabled, we see significant improvements in Ghostwire: Tokyo (DX12), Metro Exodus PC Enhanced Edition (DXR), and Wolfenstein: Youngblood (RTX) in terms of frametime consistency; but also noteworthy performance regressions in Ghostwire: Tokyo (DX12) in terms of raw performance, LEGO® Builder’s Journey (DX12 & RTX modes) and Quake 2 RTX (Vulkan Ray Pipeline & Vulkan Ray Query modes) in terms of frametime consistency. Both LEGO® Builder’s Journey and Quake 2 RTX regressions are striking and are associated with severe and consistent frametime stability and frame-pacing issues during testing and gameplay.

Also, we saw inconsistent and low GPU load in Tom Clancy’s The Division 2 (DX12) and experienced random crashes in Horizon Zero Dawn (DX12) with HAGS enabled.

Disclaimer

Please be aware that the following results, notes, and the corresponding HAGS’ state recommendation are valid for similar Ampere gaming rigs using GeForce Game Ready 512.15 driver and Windows 11 v21H2. Its representativeness, applicability, and usefulness on different GPU architectures, testing benches, GPU drivers, and MS Windows versions may vary.

Conclusion

Based on our previous results and findings, although we acknowledge that HAGS performance results are better on Windows 11 than we showed in the past using Windows 10, we still see significant performance inconsistencies that prevent us from recommending HAGS for general or global use for GeForce gamers.

Anyway, the HAGS feature is still quite promising and can improve performance in some cases, so we also recommend doing your testing to see how it works with your gaming rig and set of favorite games.

The Windows 11 OS upgrade (version 21H2, build 22000) started to become publicly available a month ago, and this performance analysis will showcase gaming using both the reference AMD Radeon RX 6700 XT and the Gigabyte AORUS GeForce RTX 3080 MASTER.

Our testing platform is a recent install of Windows 11 and Windows 10 64-bit Pro Edition, an i9-9900K with stock clocks, a Gigabyte Z390 AORUS PRO motherboard, and 32GB of T-FORCE XTREEM ARGB WHITE DDR4 3200MHz paired with our RX 6700 XT, and 32GB of Kingston DDR4 3333MHz paired with our RTX 3080. The games tested, settings, hardware, and Adrenalin and GeForce drivers are identical except for the Windows OS builds we compare.

The Performance Summary Charts – Windows 11 21H2 vs. Windows 10 21H1

Below are the summary charts of 23 games plus 4 hybrid and 4 non-synthetic benchmarks used to compare the performance changes for the reference RX 6700 XT and the AORUS RTX 3080 MASTER from the Windows 10 May 2021 (21H1) version to the latest Windows 11 (21H2) version.

You can see the list of graphics settings on the charts, and we run each built-in or custom game benchmark’s sequence at 2560×1440, except for Borderlands 3, Days Gone, Far Cry New Dawn, and Far Cry 6, tested at 3840×2160 resolution when using our RTX 3080; and LEGO® Builder’s Journey (DX12 & DXR) and Watch Dogs: Legion (DXR) which are tested at 1920×1080 resolution when using our RX 6700 XT.

Windows 11 Performance Analysis Charts

Notes on Win dows 11 (21H2) performance

We found no significant differences in gaming performance using the latest Windows 11 (21H2) version compared with Windows 10 May 2021 (21H1) version using our RX 6700 XT and RTX 3080. Overall, the results are well within what is considered our 3% margin of error, or ‘benchmarking noise’.

Let’s head to our conclusion.

Disclaimer

Please be aware that the following results, notes, and the corresponding Windows OS version recommendation are valid for similar Radeon or GeForce gaming rigs using Adrenalin 21.11.1 or GeForce Game Ready 496.49 drivers. Its representativeness, applicability, and usefulness on different Windows versions, GPU architectures, testing benches, and GPU drivers may vary.

Conclusion

Based on our previous results and findings, we recommend upgrading to the latest Windows 11 version (21H2) since its raw performance and smoothness or frametimes consistency level is approximately on par with Windows 10 version 21H1.

Finally, we found the latest public Windows 11 build to be functionally stable and relatively bug-free.

Let’s Play!
