CS2 Mouse Acceleration Guide - Turn It Off Properly

Mouse acceleration means the distance your crosshair travels depends on how fast you move your mouse, not just how far. For an aim-based game like CS2, that is poison: it makes the same flick land in a different place every time. Disabling it fully is one of the first things any serious player should do. Here is how to do it properly, in all three places it can hide.

This is the foundation under best CS2 sensitivity and the CS2 DPI guide.

Why Acceleration Hurts Aim

Aim in CS2 is built on muscle memory: a flick of a certain physical distance should always move your crosshair the same amount. With acceleration on, a fast flick moves further than a slow one of the same distance, so your brain can never learn a reliable relationship between hand movement and crosshair movement. Turning it off makes your aim consistent and trainable.

Step 1: Windows

Windows has acceleration on by default, disguised as "Enhance pointer precision":

1. Open Settings > Bluetooth & devices > Mouse > Additional mouse settings.
2. Go to the Pointer Options tab.
3. Uncheck "Enhance pointer precision."
4. Leave the pointer speed slider at the middle (6th) notch, which is 1:1.

Step 2: In-Game

CS2 uses raw input by default, which bypasses Windows mouse settings entirely. Confirm it in the console or settings:

m_rawinput 1

With raw input on, the game reads your mouse directly, ignoring Windows acceleration and pointer speed. There is no built-in CS2 acceleration to worry about when raw input is enabled, so this is mostly a confirmation step.

Step 3: Your Mouse Software

Some gaming mice have their own acceleration or "angle snapping" options in software like Logitech G Hub or Razer Synapse. Open your mouse software and make sure any acceleration setting is off. Set a native DPI step (400 or 800 are standard) rather than an interpolated value.

Verifying It Is Off

Do a simple test: place your crosshair on a spot, then move your mouse the same physical distance slowly and quickly. With acceleration off, the crosshair lands in the same place both times. If it moves further on the fast motion, acceleration is still active somewhere.

Takeaway

Mouse acceleration destroys the consistency CS2 aim depends on. Turn off "Enhance pointer precision" in Windows, confirm m_rawinput 1 in-game, and disable any acceleration in your mouse software. Then verify with the slow-vs-fast test. Once it is off, your sensitivity and DPI choices can finally build reliable muscle memory.
