Windows 11 24H2 Gaming Optimization Guide — Fix FPS Drops, VBS & Kernel Latency (2026)
According to FPSBooster.net kernel benchmarks on Windows 11 24H2, four system settings account for up to +38% Average FPS and +75% 1% Low FPS gains: (1) Disabling Virtualization-Based Security (VBS / Memory Integrity), (2) Enabling GlobalTimerResolutionRequests in the kernel registry and locking timer precision to 0.500ms, (3) Setting MMCSS SystemResponsiveness to 0% with Win32PrioritySeparation = 0x26, and (4) Automating Standby Memory List purging.
1. Enable GlobalTimerResolutionRequests in Windows 11 Kernel
-3.2ms Frame JitterHKLM\SYSTEM\CurrentControlSet\Control\Session Manager\kernel -> GlobalTimerResolutionRequests = 1 (DWORD)
Windows 11 ignores global 0.5ms timer calls unless this registry key is enabled. Run the reg add command above and reboot once.
2. Dedicate 100% Multimedia Scheduler (MMCSS) & Foreground Quantum to Games
+18% 1% Low FPSSystemResponsiveness = 0 | GPU Priority = 8 | Priority = 6 | Win32PrioritySeparation = 0x26
By default, Windows reserves 20% of CPU time for background tasks. Setting SystemResponsiveness to 0 unlocks full priority for games.
3. Unlock Hidden 'Ultimate Performance' Power Scheme & Unpark CPU Cores

Prevents CPU cores from entering deep C6/C7 sleep states during calm moments in tactical shooters.
