Detailed analysis

Windows 11 has several known gaming performance issues compared to Windows
10. Most are fixable without downgrading.

Known issues and fixes:

VBS/HVCI performance hit (5-25% FPS loss): Windows Security > Device Security > Core Isolation > Memory Integrity > Off. This is the single biggest performance difference
AMD fTPM stutter: If you get random 1-second freezes every few minutes on AMD Ryzen, disable fTPM in BIOS or update to AGESA 1.2.0.7+ BIOS. AMD fixed this in newer BIOS versions
Intel E-core scheduling: Some older games perform worse because Windows schedules their threads on efficiency cores. Fix: in Task Manager > Details > right-click game > Set Affinity > uncheck E-cores (the higher-numbered cores)
Explorer.exe memory leak: Windows 11 Explorer leaks memory over time. Fix: restart Explorer periodically or before gaming (Task Manager > right-click Windows Explorer > Restart)
Timer resolution: Some older games relied on 1ms timer resolution. Windows 11 changed this. Fix: use Windows 11 24H2 or later which restored the old behavior
Update to the latest Windows 11 version — Microsoft fixes gaming regressions in each update. Run 'winver' to check your version
