Windows 11 vs Windows 10 GPUs Tested: Which Games Faster?

I've been rather happily running and benchmarking graphics cards with Windows 10 since just after it launched in 2015. Microsoft tried to encourage people to upgrade by initially offering Windows 10 for free, plus it was the only OS with support for DirectX 12. Portions of DX12 were eventually backported to Windows 7, and you can still get Windows 10 for cheap, but now Windows 11 is the new kid on the block. So how does it perform, specifically with games? That's what we wanted to find out, so we grabbed the two best graphics cards from AMD and Nvidia and put them to the test.

Let's be clear: Change for the sake of change doesn't go over well with me, and Windows 11 puts a new coat of paint on the worn-in and comfortable feeling Windows 10 house I've been living in since 2015. A new coat of paint would be fine, and I'm not necessarily averse to that. But in the process, it seems as though the UI designers felt a need to rearrange the furniture, switch around the drawers, and clean house on a bunch of functionality that I actually like.

We've covered some of the worst Windows 11 changes, and how to fix them. Ultimately, two months after release, our Windows 11 launch impressions remain largely unchanged, and we're discovering even more disappointing aspects to the OS—like the Windows 11 SSD issues, which apparently still persist. With that in mind, I wanted to verify that Windows 11 doesn't impact graphics card performance before switching to the new OS. Of course, that switch is still in the works since I'll be shifting to an Alder Lake Core i9-12900K system for GPU reviews in the near future. And of course, using Alder Lake is one of the only good (sort of) reasons to switch to Windows 11, thanks to the new process scheduler that integrates with Intel's Thread Director hardware.

What if you're not using Alder Lake, though? I took my current GPU testbed, which is now about three years old, and did a clean install of Windows 11 on a new Crucial P5 Plus SSD for testing purposes. I tested basically the fastest graphics cards from AMD and Nvidia, the Radeon RX 6900 XT and GeForce RTX 3080 Ti, and I also retested those cards on Windows 10 using the latest drivers and updates. (Yes, technically the 3090 is a bit faster and has twice the VRAM, but it's close enough and the 3080 Ti tends to be more readily available.) That means running the AMD 21.21.1 and Nvidia's 497.09 drivers, with a complete driver cleanup (via Display Driver Uninstaller) between testing. Here are the results of the 14 games I used for testing.

If you were looking for yet another reason to hate on Windows 11, this is obviously disappointing. For those who are more open-minded, though, this is good news. Windows 11 may not be any faster at games than Windows 10, but neither is it any slower. Of course, we tested Windows 11 with VBS disabled—that was the default after a clean install on our test hardware. There has been some concern that VBS defaults to enabled on clean installs, but so far it looks like it needs to be explicitly enabled, which is likely only something you'll see from large OEMs and business PCs.

Across our 14-game test suite, the overall performance difference between Windows 10 and Windows 11 at three resolutions was less than one percent. There was one instance where Win10 was 4% faster (RTX 3080 Ti in Far Cry 6), and Assassin's Creed Valhalla was consistently 3% faster, but a few minor anomalies are to be expected. Sometimes Windows 10 was a bit faster and sometimes Windows 11 came out ahead, but in practice there wasn't any significant change.

The minimum fps (technically 99th percentile frametime converted to fps) results show a bit more variability, but that's always the case. Here we see an instance (Strange Brigade on the RTX 3080 Ti) where Win10 beat Win11 by 10%, and there are a few other cases of 5% differences, but a single frame or two rendering slowly can easily skew the results. That's why we don't place as much emphasis on minimum fps.

Interestingly, the RX 6900 XT was far more consistent in its performance across the two versions of Windows, where average fps was within 0.3% overall, and the biggest differences were still less than 2%. Even the minimum fps only had up to a 5.5% difference, and in that case, it was Windows 11 coming out ahead.

If you prefer seeing things in chart form rather than the above tables, here's a gallery of all 45 of the 1080p, 1440p, and 4K results. (Note: The above table uses the geometric mean for average, where all values are given equal weight, while the 14 game average charts below use the arithmetic mean and can skew due to "outlier" results.)

While these results are boring in general, they're good news because I'd hate to see the new OS penalize or benefit performance. Hopefully, Microsoft will walk back some of the UI changes, or maybe I'll just need to execute my own workarounds. Either way, my new Alder Lake build will basically require Windows 11, plus retesting all the GPUs on our new 2022 test suite. So that's how I'll spend much of January, I think.

If you're curious, I'm planning on using the following games for the coming year of graphics card reviews: Borderlands 3, Dirt 5, Far Cry 6, Flight Simulator, Forza Horizon 5, Horizon Zero Dawn, Red Dead Redemption 2, and Watch Dogs Legion. Note that seven of those use DirectX 12, with Red Dead being the sole Vulkan representative—and there are no DirectX 11 games in the list. I'll also use a somewhat different suite for ray tracing tests: Bright Memory Infinite, Control, Cyberpunk 2077, Far Cry 6, Fortnite, Metro Exodus Enhanced, Minecraft, and Watch Dogs Legion, with the goal being to use games that show some real visual benefits from enabling ray tracing. (Feel free to comment below if you think I've missed any game that warrants inclusion.)
