Windows 11 Affect On Gaming Performance

Windows 11 Might Affect Gaming Performance On Some Prebuilt PCs

Microsoft will be enabling VBS on most new PCs over this next year which can hinder gaming performance by somewhere near 25%.
 
Despite Microsoft’s claims that “if you’re a gamer, Windows 11 was made for you” future prebuilt PCs with the new OS factory installed may experience drops in frame rate by around 28%

This issue is primarily caused by a setting called Virtualization-Based Security (VBS) which was introduced in Windows 10 which uses hardware and software virtualisation to create an isolated subsystem to protect your PC from malware.The feature mainly intended for enterprise customers to be able to lock down the corporate PCs they drop into their offices and make sure they don’t get compromised.

PCs which are upgrading from Windows 10 to Windows 11 don’t have to worry about VBS being enabled, unless an enterprise version of the older OS was the one that was running. The issue arises if you’re using a machine which has already had an OEM build of Windows 11 installed on it.
 

Some games which have been tested on windows 11 with VBS enabled have shown some
interesting results:

Far Cry New Dawn is barely affected at VBS, being an exceptional case, with just a 5%
reduction in frame rate. But Horizon Zero Dawn drops by some 25%, Metro Exodus by 24%,
and Shadow of the Tomb Raider by 28%. Interestingly, the 3DMark Time Spy score only
dropped by 10%.
 
The enablement of VBS isn’t having an impact on the actual speed of the hardware in the
system, however.Over multiple benchmark runs of Metro Exodus and the CPU or graphics
card aren’t slowing down. The average frequency of the GPU and CPU actually barely
changes.
