When Windows 11 was released, Microsoft turned on two functions: virtualization-based security (VBS) and Hypervisor mandatory code consistency check (HVCI) by default, which caused quite a lot of controversy, and many people were worried about whether they would affect performance. Recently, Windows 10 seems to have started to turn on VBS by default.
Foreign blogger Tom's Haredware conducted a comparison test to test whether VBS will really affect gaming performance: the test system is the latest version of Windows 11 64-bit Professional Edition, with hardware configurations: i9-13900K, RTX 4090 (528.49 version driver), MSI MEG Z790ACE, Zhiqi Trident Z5 DDR5-6600 16GB x 2, Sabrent Rocket 4 Plus-G 4TB.
There are 15 test games in total, including 6 ray tracing, 6 DX12, 2 DX11, and 1 Vulkan. Each game tests four levels: 1080p medium-quality, 1080 high-quality, 2K high-quality, and 4K high-quality, and examines the two indicators of average frame rate and 1% minimum frame.
Comparing the 120 sets of data, after closing VBS, as many as 118 sets of data increased, and the only two declines were only 0.1% and 0.2%, which is completely an error. On average, after VBS was turned off, the game frame rate increased by 2.1% at 4K, and the picture quality increased by 5.3% in 1080p, which means that the lower the resolution and the lower the picture quality, the greater the difference, and there are as many as 26 groups with changes of more than 5%.
Among them, "Microsoft Flight Simulation" increased by 11.2% at low image quality of 1080p, which is the biggest impact, and the other three sets of settings also increased by about 9%. The most exaggerated thing is "Total War: Warhammer 3". The improvement in 1080p high picture quality actually reached an exaggerated 37.7%, and 28.6% under 2K high picture quality!
Disabling VBS will bring some security risks to your PC. Although it is very tiny for home gaming machines, players should be more careful.
The method of manually closing VBS is as follows:
Open Windows terminal (administrator) - enter bcdedit /set hypervisorlaunchtype off command - Enter to confirm - just restart the computer
