Mouse Acceleration and Why to Disable It

Mouse acceleration causes cursor speed to increase based on physical movement speed—faster physical movement makes the cursor jump farther. This introduces inconsistency: the same flick movement produces different crosshair distances depending on speed. Competitive games require consistent aiming where muscle memory works predictably.

Windows mouse acceleration (called 'Enhance Pointer Precision') must be disabled for competitive play. Go to Control Panel > Mouse Properties > Pointer Options tab and uncheck 'Enhance pointer precision.' This ensures 1:1 mouse tracking—physical movement distance directly corresponds to cursor distance without acceleration modification.

Even with Windows acceleration disabled, some mice apply acceleration through hardware. Check your mouse driver software (Corsair, Razer, SteelSeries, etc.) for acceleration settings and disable them there. Ideally, acceleration should be disabled at all levels: Windows, mouse driver, and in-game (enable Raw Input in CS2).

CS2's Raw Input setting (Settings > Mouse > Raw Input) reads mouse movement directly from hardware, bypassing Windows mouse processing. Enable Raw Input to ensure game receives unfiltered mouse data. Combined with Windows acceleration disabled, Raw Input ensures completely consistent aiming.
