Windows 11 will hobble gaming performance by default on some prebuilt PCs:

Despite Microsoft's claims that "if you're a gamer, Windows 11 was made for you" you will need to watch out for future prebuilt PCs with the new OS factory installed. That's because the Big M is enabling more security features in PCs by default, and one in particular can seriously tank gaming performance.

In our testing, that can add up to as much as a 28% drop in average frame rates. And you thought the TPM 2.0 restrictions were a pain...

That sort of frame rate delta is like dropping down an entire tier of graphics card and, in these days where GPUs are so hard to come by, Microsoft gimping the performance of the chip in your newbuild machine would surely be hard for gamers to stomach.

The issue is Virtualization-Based Security (VBS), a setting introduced into Windows 10 which uses hardware and software virtualisation to enhance the security of your system. It basically creates an isolated subsystem that helps prevent malware from screwing your PC.
