Windows 11 introduced significant changes under the hood — some that help gaming, some that hurt it. This guide separates the effective optimizations from the myth and placebo tweaks that circulate online.
Power Plan — Non-Negotiable
Switch from Balanced to High Performance immediately. Go to Control Panel → Hardware and Sound → Power Options → Show additional plans → High Performance. Unlock Ultimate Performance via admin PowerShell: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
Game Mode and GPU Scheduling
Go to Settings → System → Gaming. Enable Game Mode — it reliably improves frame rate stability by deprioritizing background tasks. Enable Hardware-Accelerated GPU Scheduling (HAGS) on modern GPUs (RTX 30+, RX 6000+).

See Services →Security Features That Cost FPS
Memory Integrity (VBS): Windows Security → Device Security → Core Isolation → Memory Integrity → Off. This can reduce FPS by 5–15% on some games.
Background Apps and Startup
- Settings → Apps → Startup — disable every unnecessary startup app
- Disable Xbox Game Bar and all background recording
- Disable Windows Search indexing on game drives
- Set Visual Effects to "Adjust for best performance" in System Properties
Driver and Update Management
Disable Receive updates for other Microsoft products in Windows Update settings — this prevents Windows from automatically pushing GPU driver updates. Manage GPU drivers manually using DDU and clean installs.
