VBS is enabled by default after a clean install of Windows 11, but not when upgrading from Windows 10. 'In our testing with pre-release builds of Windows 11,' UL tells us, 'a feature called Virtualization-based Security (VBS) causes performance to drop. When it updated us about Windows 11 support being baked into its full benchmarking suite of products, it made note about this performance-damaging security feature. Why is that interesting? Because it was actually UL who brought this issue to our attention. Interestingly, the 3DMark Time Spy score only dropped by 10%. But Horizon Zero Dawn drops by some 25%, Metro Exodus by 24%, and Shadow of the Tomb Raider by 28%. We've tested a selection of games on the current release build of Windows 11, with VBS off and VBS enabled (though not actually running) and the impact is obvious.įar Cry New Dawn is the outlier here, which barely shrugs at VBS, with just a 5% reduction in frame rate.
