Windows 11 introduced several changes that affect gaming performance. If you're not hitting the frame rates your hardware should deliver, this guide addresses all Windows 11-specific issues and their fixes.
Windows 11 Power Plan Fix
Windows 11 defaults to a Balanced power plan that throttles CPU performance. Press Win+R, type powercfg.cpl, and switch to High Performance. Unlock Ultimate Performance via admin PowerShell: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
Windows 11 VBS and Memory Integrity
Go to Windows Security → Device Security → Core isolation and toggle Memory Integrity off, then restart. This can improve gaming performance by 5–15% on some systems.

Windows 11 sometimes installs generic GPU drivers through Windows Update. Download DDU (Display Driver Uninstaller), boot into Safe Mode, run DDU to completely remove existing drivers, then install the latest drivers directly from NVIDIA or AMD.
