Windows timer resolution controls how precisely the OS schedules operations — 1ms means smoother frame delivery, 15.6ms means choppier. Windows 11 changed default timer behavior, and many gamers noticed worse frame pacing vs Windows
10.
The history:
- Windows 10: any app requesting 1ms timer made it system-wide (games benefited automatically)
- Windows 11 (pre-24H2): each process gets its own timer. Games that don't request 1ms get 15.6ms
- Windows 11 24H2+: partially restored global timer, improving the situation
How to fix:
- Update to Windows 11 24H2 or later — fixes the worst timer issues
- Use ISLC (Intelligent Standby List Cleaner) from Wagnardsoft — it includes timer resolution. Set to 0.5ms
- Check current timer: download TimerTool to see your system timer resolution
- Avoid Chrome or Discord with hardware acceleration — they sometimes change the system timer
- For competitive games: ISLC's timer resolution feature is the most reliable fix
- Don't use third-party 'timer resolution' tools that permanently modify the system — ISLC is safer and reversible
