Newer CPUs (like Intel 12th Gen or AMD Ryzen 5000 and above) handle this overhead much better, typically seeing only a 3-5% drop . Older supported CPUs experience more significant stutters and lag.
Independent testing has shown that having VBS and HVCI enabled can reduce gaming performance by 5% to 25% , depending on the hardware.
A core feature of VBS, Hypervisor-Protected Code Integrity (HVCI) ensures that only trusted, signed drivers can run in the kernel. This prevents malware from injecting malicious code at the deepest levels of your system.
