| Tweak | Latency Reduction | Difficulty |
|---|---|---|
| Enable Raw Input (in-game) | -2 to 5ms | Easy |
| Disable Mouse Acceleration | -3ms perceived | Easy |
| Max Refresh Rate + Disable VSync | -5 to 15ms | Easy |
| Enable HAGS | -2 to 5ms GPU latency | Easy |
| Ultimate Performance Power Plan | -3 to 8ms CPU latency | Easy |
| Set USB Polling Rate to 1000Hz | -1 to 4ms | Easy |
| DPC + Timer Tweaks (SageTweaks) | -5 to 15ms total | Automated |
Apply these 8 tweaks to minimize input lag at every layer — peripheral, OS, GPU, and display.
Raw input bypasses Windows mouse acceleration and input processing, sending mouse movement data directly from the hardware to the game. In Valorant: Settings to Mouse to Input Method to Raw Input. In CS2: Settings to Keyboard/Mouse to Raw Input to Enabled. In most games, this is the single highest-impact input lag reduction available.
Go to Windows Settings, Bluetooth and devices, Mouse, Additional mouse settings, Pointer Options tab. Uncheck Enhance pointer precision. Mouse acceleration changes cursor speed based on how fast you move the mouse, adding inconsistency and perceived lag.
Right-click Desktop, Display settings, Advanced display settings. Set Refresh Rate to the maximum your monitor supports. Higher refresh rate directly reduces input lag. Also disable VSync in both Windows and game settings.
Wireless peripherals add 1-8ms of wireless transmission latency. Wired mice eliminate wireless delay entirely. If you must use wireless, ensure your mouse runs at 1000Hz polling rate. Check manufacturer software for polling rate settings.
Go to Windows Settings, System, Display, Graphics, Change default graphics settings, enable Hardware-accelerated GPU scheduling. HAGS reduces the time between the CPU issuing a GPU command and the GPU executing it, cutting GPU-side input lag by 2-5ms on supported Nvidia RTX 2000+ and AMD RX 5000+ GPUs.
Open PowerShell as Administrator and run: powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61. Then select Ultimate Performance in Power Options. The Ultimate Performance plan keeps the CPU at full speed constantly, reducing processing latency by 3-8ms.
Most gaming mice support 1000Hz polling rate but may ship at 500Hz or 125Hz. Open your mouse software and set the polling rate to 1000Hz. Some mice support 4000Hz or 8000Hz which reduce input latency further. 1000Hz is the standard competitive baseline.
DPC (Deferred Procedure Call) latency is a common cause of inconsistent input response on Windows. Audio drivers, network drivers, and USB controllers can cause spikes. SageTweaks helps tune DPC-related settings, timer behavior, USB/input controls, and selected system tweaks from the verified catalog.
Input lag is the total time between a physical action (mouse click, key press) and the corresponding action appearing on your screen. In competitive gaming, even 10-15ms of additional latency can mean the difference between winning and losing a gunfight. Most gamers have 30-50ms total input lag without optimization.
You can measure system-level latency using tools like NVIDIA FrameView, LatencyMon (free), or Mouse Tester. For game-specific input lag, NVIDIA Reflex Analyzer requires a compatible monitor and GPU. LatencyMon is the best starting point as it identifies which drivers are causing latency spikes.
Yes, significantly. Input lag at the display level equals 1000ms divided by refresh rate. A 60Hz monitor adds 16.7ms. A 144Hz monitor adds 6.9ms. A 240Hz monitor adds 4.2ms. Upgrading from 60Hz to 144Hz cuts display-side input lag in half.
Yes. VSync forces the GPU to wait for the monitor refresh cycle before rendering a new frame, adding 1-2 frames of input lag. Disabling VSync eliminates this delay. If you experience screen tearing without VSync, use NVIDIA G-Sync or AMD FreeSync instead.
Common causes: VSync enabled, wrong power plan causing CPU throttling, DPC latency spikes from drivers, USB polling rate too low, mouse acceleration enabled, or game running in Windowed Fullscreen instead of exclusive Fullscreen.
SageTweaks applies DPC latency fixes, timer resolution optimization, USB polling tweaks, and selected system optimizations from the verified catalog in guided sessions.
