Windows 11 enables Virtualization-Based Security (VBS) and Core Isolation by default, which introduces CPU scheduling penalties that cause micro-stutters and poor 1% low frame times in games — even when average FPS looks fine. Disabling Memory Integrity in Windows Security settings can eliminate these stutters and improve 1% lows by 15–25%, though it removes kernel-level exploit protection. After disabling, users should verify VBS is fully off via msinfo32 before concluding the fix worked.
