Best Windows Settings For Low Latency Gaming
Windows ships configured for general use — not competitive gaming. Every setting below has a measurable effect on end-to-end input latency. This is the complete reference list, with the highest-impact items first.
Power Settings
Power Plan → Ultimate Performance
Enable the hidden Ultimate Performance plan via Command Prompt: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61. Then set it in Settings → System → Power & battery. This disables CPU core parking and prevents clock-speed scaling during brief idle windows.
- Effect
- Eliminates CPU ramp-up latency. Estimated saving: 5–15 ms on affected systems.
- Downside
- Increases idle power draw by 10–30 W on desktop. Fine for gaming PCs.
Timer Resolution → 0.5 ms
The Windows timer controls thread scheduling granularity. Default: 15.6 ms. Set to 0.5 ms for consistent sub-millisecond scheduling. Use a timer resolution tool that persists across game launches.
- Effect
- Frame times stop quantizing to 15.6 ms multiples. High-refresh-rate monitors can fully utilize their native timing.
- Note
- Windows 11 23H2+ requires a registry key change to allow applications to set resolution below 1 ms without admin elevation. InputLag handles this automatically.
GPU Scheduling & Driver Settings
NVIDIA Control Panel
- Low Latency Mode
- Ultra — reduces pipeline pre-render depth to minimum.
- Max Pre-Rendered Frames
- 1 — eliminates buffered frame latency.
- Power Management Mode
- Prefer Maximum Performance — prevents GPU downclocking.
- Vertical Sync
- Off — control per-game instead.
- Texture Filtering Quality
- High Performance — minor quality reduction, meaningful CPU/GPU savings.
Hardware-Accelerated GPU Scheduling (HAGS)
HAGS (Settings → System → Display → Graphics → Change default graphics settings) reduces CPU overhead in the GPU scheduling path. Reduces input lag on most systems with modern drivers but can introduce frame time variance on some GPU/driver combinations. Test both states with CapFrameX.

Doing this by hand?
See your system’s optimization status, try three free starter optimizations, and review supported changes before applying them. Advanced tools are available on paid plans.

Set Maximum Refresh Rate
Right-click desktop → Display settings → Advanced display → Choose a refresh rate. Set to maximum. Windows sometimes defaults to 60 Hz even on 144 Hz monitors after updates.
Disable HDR (Unless Needed)
Windows Auto HDR processing adds 1–4 ms of SDR-to-HDR conversion overhead. Disable in Settings → System → Display → HDR for competitive play.
Input Device Settings
Mouse: Raw Input + 1000 Hz
- Pointer Precision
- Disable — removes Windows mouse acceleration curve.
- Polling Rate
- Set to 1000 Hz minimum in manufacturer software.
- Raw Input
- Enable in every game's mouse settings.
- Pointer Speed
- 6/11 (center) — no built-in scaling offset.
Keyboard: Repeat Delay
Control Panel → Keyboard → Speed: set Character repeat delay to Short, Repeat rate to Fast. Reduces the initial hold-key delay from ~500 ms to ~250 ms — irrelevant for gaming but good practice.
Windows Features to Disable
Game Mode — Enable It
Settings → Gaming → Game Mode → On. Deprioritizes background processes and optimizes thread scheduling for the active game window. Contrary to older advice, Game Mode is beneficial on Windows 11 23H2+.
Notifications & Background Apps
- Notifications
- Off while gaming — notification popups generate GPU compositing work.
- Xbox Game Bar
- Disable if not using — reduces background CPU overhead.
- Cloud backup clients
- Pause Dropbox, OneDrive, Google Backup during gaming — disk I/O interference.
Process Priority
Setting your game's process to High priority in Task Manager ensures the Windows scheduler prefers it when CPU time is contested. Do this with caution — setting too many processes to High priority defeats the purpose.
Tools like Process Lasso can automate this per-game with persistent rules, eliminating the need to manually adjust on each launch.
Frequently asked questions
Do I need to reapply these settings after Windows updates?
Power plan and timer resolution settings can reset after major Windows updates. GPU driver settings persist through OS updates but reset after driver reinstallation. Use InputLag's desktop app to maintain these configurations automatically.
Are these settings safe? Can they damage my hardware?
All settings listed are standard Windows configuration changes, not overclocking or voltage modifications. They are fully reversible. The power plan setting increases idle power draw but is within hardware design specifications.
What's the single most impactful change for someone on stock settings?
Disabling V-Sync and switching to High Performance power plan. Together, these typically save 15–35 ms of end-to-end latency on a stock Windows gaming setup — more than any hardware upgrade except the monitor itself.
