CS2 Raw Input Guide

If you’ve booted up Counter-Strike 2 and instantly opened the developer console to type m_rawinput 1, you aren't alone, but you likely noticed the command is completely missing. 

The short answer to this common point of confusion is that CS2 forces raw input ON by default, hardcoding the game to read directly from your mouse sensor while bypassing Windows OS processing entirely. But if raw input is permanently enabled, why do so many veteran players feel like their aim is "floaty" or slightly off compared to CS:GO? 

The culprit isn't your mouse input; it's a combination of Source 2's new sub-tick architecture, frametime pacing, and unoptimized system latency. In this guide, we'll break down exactly how the new input system functions and walk through the hardware and video settings you need to adjust to get that crisp, 1-to-1 competitive aim back. 

Does CS2 Use Raw Input?  

Raw input is a system that allows Counter-Strike 2 to read movement data directly from your mouse's hardware sensor, bypassing the Windows operating system entirely. Without this direct line of communication, your mouse signals are filtered through Windows first, which can apply its own sensitivity multipliers or inject built-in mouse acceleration (often labeled as "Enhance pointer precision"). 

By capturing the raw data, the game guarantees a pure 1-to-1 translation of your physical movements. This means swiping your mouse exactly five centimeters on your pad will always yield the same in-game rotation, regardless of the speed of your swipe. For competitive players relying on pinpoint flick shots and meticulous spray transfers, this unfiltered input is the absolute foundation of mechanical consistency.

How to Enable Raw Input in CS2 

In Counter-Strike 2, raw input is enabled by default and hardcoded into the game engine, meaning you do not need to manually turn it on. 

Unlike in CS:GO, where players had to use the m_rawinput 1 command or toggle a setting in the menu, CS2 natively bypasses your operating system's mouse settings (such as Windows' "Enhance pointer precision") to ensure maximum accuracy and consistency. 

Because the game always reads the unprocessed, sub-tick data directly from your mouse hardware, the old raw input commands are entirely obsolete. If your aim feels a bit off or you are trying to replicate a legacy setup, rest assured that you are already experiencing true raw input; any further fine-tuning will need to be done through your physical mouse DPI or your in-game sensitivity settings. 

CS2 Raw Input Commands Explained 

While players frequently open the developer console looking for legacy commands like m_rawinput 1 or m_customaccel, Counter-Strike 2 has completely rewritten how mouse data is handled under the hood. 

In CS2, these variables return a "command not found" error because Valve's Source 2 engine forces raw input at the system level to accommodate its sub-tick architecture. Instead of waiting for the game's server tickrate to sample your cursor position, CS2 constantly tracks your mouse hardware's polling rate in real-time, capturing the exact microsecond you click or flick.

Because the engine requires this ultra-precise, unadulterated stream of physical data to function correctly, Windows pointer settings and operating system mouse acceleration are bypassed automatically. Consequently, fine-tuning your input consistency no longer happens in the console; instead, it relies entirely on matching your mouse’s polling rate (such as 1000Hz or 4000Hz) with a clean, unaccelerated DPI profile in your mouse's native software. 

If you are migrating an old CS:GO config.cfg or autoexec.cfg file, any lines containing m_rawinput or older acceleration variables will simply be ignored by CS2 without breaking your other binds. 

How Mouse Input Works in CS2 

In Counter-Strike 2, mouse input is intrinsically tied to the game's sub-tick architecture, fundamentally changing how the Source 2 engine interprets player movement. Rather than waiting for the next rendered frame or server tick to sample the crosshair's location, CS2 continuously pulls raw positional data directly from the mouse hardware at its native polling rate, assigning an exact microsecond timestamp to every flick and click. 

To guarantee the absolute integrity of this data, the Source 2 engine enforces Raw Input at a hardcoded, unchangeable level, creating a direct pipeline between your peripheral and the game. This strict hardware-to-engine connection completely bypasses all Windows OS settings. 

As a result, outside variables like the Windows sensitivity slider or the notoriously inconsistent "Enhance pointer precision" (OS-level mouse acceleration) are entirely ignored by the game. By stripping away this operating system interference, CS2 ensures a perfect 1:1 translation of your physical DPI and polling data, delivering the uncompromising mechanical consistency required at the highest levels of competitive play. 

Can You Disable Raw Input in CS2? 

No, you cannot disable raw input in Counter-Strike 2. 

When Valve transitioned the game to the Source 2 engine, they permanently removed the ability to toggle this feature, rendering legacy console commands like m_rawinput 0 completely non-functional. Because the game's sub-tick architecture requires an exact, microsecond-accurate timestamp for every action, the engine mandates an uninterrupted, unadulterated feed of data straight from your mouse hardware. 

This hardcoded system means CS2 will always bypass Windows operating system settings and software-level mouse acceleration. Consequently, players looking to customize their aiming feel can no longer rely on toggling raw input or custom acceleration curves via the developer console; all adjustments must now be handled exclusively through your physical mouse DPI profiles and the in-game sensitivity slider.
