The fourth configuration we’ve included is one with Virtualization-Based Security (VBS) enabled. By default, our Windows 11 install disabled this feature, but it’s been reported that on some desktop and laptop PCs, VBS is enabled by default and can tank gaming performance by up to 25%.
It should be noted that VBS isn’t a new feature and it’s certainly not exclusive to Windows 11. You can enable it on Windows 10, but we’ve never come across a single configuration where it’s enabled by default.
To check if VBS is enabled, use Windows search, type ‘MSInfo32’ and hit Enter. Towards the bottom of the system info you’ll find if Virtualization-Based Security is enabled or not. To toggle it on/off, enter the Windows Security menu, navigate to the Device Security tab and under the header “Core isolation” you’ll find the ability to toggle disable VBS.
Cache and Memory Latency Performance
Before we jump into the application benchmarks here’s a quick look at cache and memory latency performance. In short we see no change, or virtually no change in L1, L2 or L3 cache performance with the Intel processors. Where we do see a notable performance difference is when looking at DRAM latency…

For the 10105F, the Windows 10 and Windows 11 installs deliver the same results, but enabling VBS does incur a 7% performance penalty and this will be noticed in memory-sensitive scenarios, such as gaming.
With the more powerful 11900K, we see that Windows 10 delivered the best results as the upgrade to Windows 11 increased latency by 5%, though a fresh Windows 11 install only increased latency by 3%. However, we’re again seeing a noteworthy increase with VBS enabled, this time a 9% increase is seen when compared to the Windows 10 configuration.
Moving on to Cinebench R23, we find that the 11900K produced its best result with Windows 10 though the difference is minimal, about a 1% increase over the fresh Windows 11 install. Enabling VBS had a very minor impact on performance at 2%, with the variation between the slowest and fastest configurations, and the same is also true for the Core i3 system.

The Blender Open Data is very similar to what was seen with Cinebench. The Windows 10 and Windows 11 results are essentially identical, but enabling VBS comes with a slight performance penalty, this time around 3% when compared to what we saw when using Windows 10.

Testing with Adobe Photoshop 2021 shows similar performance for all four tested configurations when using the Core i3 processor and enabling VBS resulted in a 3% performance hit.
That said, we saw a far more significant 7% performance drop with the 11900K when using VBS. However, when comparing the fresh Windows 10 and 11 installs performance was much the same.

The last application benchmark is based on Adobe Premiere Pro and we’re looking at virtually identical performance using Windows 10 or 11. The only exception is the VBS enabled config as this reduces performance by 12-13%.
Time for a few game benchmarks. Please note we’re not testing dozens upon dozens of games, rather you get the idea with just a few, so we’re going to show the results for four titles, starting with F1 2021.

Rainbow Six Siege results are interesting as VBS reduced frame rates by 11-12%, though that margin is likely exaggerated due to the extremely high frame rates. Those results aside we see identical performance from Windows 10 and Windows 11 using either CPU.
” alt=”” width=”1397″ height=”1541″ data-src=”https://static.techspot.com/articles-info/2349/bench/CP2077.png” />
The last game we tested was Cyberpunk 2077 and here we’re looking at a ~8% performance hit with VBS installed. Other than that, performance is the same when comparing Windows 10 and 11.
” alt=”” width=”1405″ height=”1538″ data-src=”https://static.techspot.com/articles-info/2349/bench/Load-2.png” />
Interestingly, Windows 11 was also slower to load when compared to Windows 10, though the margin when running the 11900K is insignificant. Where the difference was somewhat more significant was with the Core i3 processor as Windows 11 took almost 40% longer to load, though that’s a mere 3 second change. Still for our configuration Windows 11 didn’t improve boot times.
Before wrapping up testing, here’s a look at storage performance with CrystalDiskMark. Read and write sequential performance is the same regardless of the configuration, so nothing to report here. However, the random queue depth 32 results are interesting.
Windows 11 is offering a massive increase in write performance over Windows 10. To be entirely honest, I’m no longer familiar with SSD testing and I haven’t run CrystalDiskMark in years, but I can tell you after multiple system resets the results were repeatable and I did completely fill the brand new SSD before I began testing.

So I believe the 20-26% performance increase we’re seeing here with the 11900K is accurate, I’m just not sure why we’re seeing such a substantial performance improvement. There was even a 10% uplift from Windows 10 to 11 with the Core i3 processor despite the results being much lower overall.
Another interesting point to note is that VBS cripples storage throughput, lowering both read and write performance. With the 11900K we’re looking at a 21% drop for read throughput and a massive 58% drop in write throughput, or another way of putting it, Windows 11’s random write performance was almost 2.5x faster with VBS disabled.
What We Learned
There you have it. For the most part there is little to no difference between Windows 11 and Windows 10 using Intel 10th and 11th-gen Core series processors across gaming, application, and storage performance. If you’ve experienced a notable drop in performance since upgrading, it’s well worth checking to see if VBS is enabled and do something about that as we explained in the intro.
It’s also worth noting that for maximum performance you’re better off starting over with a fresh install of Windows 11. Besides the small performance loss that was seen with the upgraded install, we also on occasion randomly suffered blue screen crashes when loading Windows 11, something that never happened with the fresh install.
