Input Lag Reducer + Display Optimizer

Safe one‑click-ish steps to cut input latency and dial in your display for gaming. Nothing invasive; everything is reversible.

Input Lag Reducer

USB power, polling, and driver priority hints

Disable USB selective suspend (prevents mouse/keyboard from sleeping):

powercfg /SETACVALUEINDEX SCHEME_CURRENT SUB_USB USBSELECTIVESUSPEND 0
powercfg /SETDCVALUEINDEX SCHEME_CURRENT SUB_USB USBSELECTIVESUSPEND 0
powercfg /SETACTIVE SCHEME_CURRENT

Mouse software: set polling rate to your device’s max stable value (generally 1000 Hz; some pro mice support 2K–8K).
Device Manager → Universal Serial Bus controllers → for each USB Root Hub (USB 3.0+): Properties → Power Management → uncheck “Allow the computer to turn off this device to save power”.
GPU panel: enable low‑latency modes.
- NVIDIA: Low Latency Mode = On/Ultra per game; set Max Frame Rate to your monitor’s refresh or slightly below.
- AMD: Anti‑Lag/Anti‑Lag+ On; set FRTC cap if available.
- Intel Arc: Low Latency toggle On; set FPS limit.

Display Optimizer

Resolution, refresh rate, HDR/SDR, color profile

Set highest refresh: Open Advanced display settings then pick the max refresh rate for your gaming monitor.
Open advanced display
GPU control panel → set scaling to display (or GPU if needed) and ensure your desktop uses native resolution.
Color profile: Install the monitor ICC from the manufacturer when available. Then apply via Color Management → Devices → Add… → Set as Default Profile.
Optional: Hardware‑accelerated GPU scheduling (HAGS)
Settings → System → Display → Graphics → Default settings → toggle “Hardware‑accelerated GPU scheduling”.
