How to Reduce Input Lag in Valorant: The Definitive Guide

In Valorant, the difference between winning and losing a duel can be a fraction of a second. And if you feel like your mouse "doesn't obey" or that there's a delay between what you do and what happens on screen, you're suffering from input lag — and there's a real solution, without upgrading hardware.

In this guide, you'll understand every source of input lag in Valorant and how to eliminate them one by one — from the basics to the advanced kernel tweaks that make the difference in decisive duels.

What is input lag and why it destroys your aim in Valorant

Input lag is the total time between you moving the mouse and the result appearing on screen. In Valorant, where 1v1 duels are decided in milliseconds and peek advantage is real, every extra ms is a competitive disadvantage.

Total input lag is the sum of several layers:

• Peripheral latency: your mouse sends position every 1ms (1000Hz) or 8ms (125Hz) — a huge difference
• Driver input processing: Windows processes mouse input before passing it to the game — USB and registry tweaks reduce this
• Render latency: the time CPU/GPU takes to process the current frame — the higher the FPS, the lower this delay
• Display latency: the monitor has its own delay — TN panels are faster than IPS/VA in this regard
• Vsync latency: with Vsync enabled, the game holds frames to sync with the monitor — adds 1-2 frames of delay
• Operating system: scheduler, timer resolution, and background processes introduce variable latency

Valorant settings for minimal input lag

Critical graphics settings

• Vsync: ALWAYS disabled — absolute rule
• Limit FPS Always: enabled at double your monitor's refresh rate (144Hz monitor → 288 FPS; 240Hz → 480 FPS). FPS above the refresh rate reduces render latency
• NVIDIA Reflex: Enabled + Boost — reduces pipeline latency by cutting frames from the render queue before they're sent to the monitor
• Multithreaded Rendering: enabled — distributes CPU load across cores
• Overall quality: Low on everything — less GPU load = higher FPS = lower render latency
• Anti-Aliasing: None or MSAA x2 at most
• Display mode: Fullscreen exclusive (NEVER borderless — it adds a frame of latency)

Windows settings to reduce input lag

Disable Vsync globally on the GPU

Even with Vsync disabled in Valorant, if the NVIDIA Control Panel or AMD Software has global Vsync enabled, it will enforce Vsync anyway. Open NVIDIA Control Panel → Manage 3D Settings → Vertical Sync → Off.

Ultimate Performance power plan

A CPU with active P-States dynamically scales frequency — during this frequency transition, latency varies. For consistent and minimal input lag, the CPU needs to operate at maximum frequency at all times. The "Ultimate Performance" plan disables this scaling.

Mouse polling rate at 1000Hz

Mice at 125Hz send position 8 times per second — one update every 8ms. At 1000Hz, every 1ms. In Valorant, where micro-aim adjustments matter, this difference is noticeable especially during spray transfers. Enable it in your mouse software settings (Razer Synapse, Logitech G Hub, etc.).

Disable mouse acceleration

Enhanced Pointer Precision makes the cursor travel different distances depending on movement speed — great for general use, lethal for FPS aiming. Disable it: Settings → Bluetooth & devices → Mouse → Additional mouse settings → Pointer Options → uncheck "Enhance pointer precision".

Raw Input in Valorant

In Valorant's control settings, enable "Raw Input Buffer" — this makes the game read mouse input directly from the driver, bypassing the Windows processing layer. It reduces input latency and eliminates residual acceleration inconsistencies.

Advanced tweaks: USB, Timer Resolution, and IRQ

USB polling and controller

Your PC's USB controller processes mouse interrupts before passing them to the driver. A USB controller with high DPC Latency can add variable ms of delay to your input. In the advanced properties of the USB controller (Device Manager), some Power Management settings can be disabled to reduce this delay.

Timer Resolution

Windows defaults to a timer resolution of 15.6ms — meaning the system scheduler "wakes up" every 15.6ms. For gaming, you can reduce this to 0.5ms using SetTimerResolution. With a more precise timer, the scheduler distributes CPU time with much finer granularity, reducing render latency variation between frames.

Win32PrioritySeparation for Valorant

The registry parameter Win32PrioritySeparation controls how Windows distributes CPU time to the foreground process vs background. Configuring it correctly ensures Valorant receives as much CPU time as possible, reducing render latency.

What UPBOOST applies for Valorant

All of the tweaks above — plus a deeper layer of optimizations including DPC Latency diagnosis with LatencyMon, IRQ Affinity configuration to isolate mouse interrupts on specific cores, timer resolution tuning, and validation of all NVIDIA/AMD driver settings.

UPBOOST Valorant clients report:

• Noticeably more responsive mouse — more "direct" movement
• More consistent click timing in close duels
• Stable FPS above 200 even in smoke + molotov situations
• Much higher 1% low — without the drops that cost decisive rounds
