MOUSE ACCELERATION TEST

Mouse acceleration makes your cursor move farther when you move your mouse faster. At low speeds the cursor moves less, and at high speeds it moves more, but not proportionally. This makes muscle memory inconsistent because the same physical movement produces different cursor results depending on speed. The OS attempts to guess your intent, giving you precision when moving slowly and speed when moving fast, but the side effect is destroyed aim consistency.

Yes, for gaming, you should absolutely disable mouse acceleration. The default Windows setting is 'Enhance pointer precision' which enables acceleration by default. Competitive gamers need 1:1 raw input for reliable muscle memory. The only exception is for productivity or design work where acceleration can be helpful — in that case, use a separate profile or mouse for gaming.

On Windows: Mouse Settings → Additional Mouse Options → Pointer Options tab → uncheck 'Enhance Pointer Precision'. In mouse driver software (Synapse, G Hub, iCUE): check the DPI/Performance tab for any acceleration slider and set to 0. In games: ensure 'Raw Input' or 'Disable Mouse Acceleration' is enabled. On macOS: run 'defaults write .GlobalPreferences com.apple.mouse.scaling 0' in Terminal. You must disable at all three levels to guarantee raw input.

Acceleration destroys the contract that muscle memory depends on. Your brain learns that 'this much hand movement = this much cursor movement,' but with acceleration, that mapping changes with hand speed. A flick shot in practice is one distance; a flick shot in a panic situation is faster and thus a different distance. Aim becomes unpredictable. It also makes tracking moving targets very difficult because your sensitivity is constantly changing as your tracking speed varies.

Most modern gaming mice (post-2018) do not have hardware acceleration built in. Their sensors report raw 1:1 data to the firmware, which forwards it raw to the PC. However, some older mice and many office mice do have hardware acceleration in the firmware. To check, run the physical pen test: if the same physical distance produces different cursor distances at different speeds, acceleration is present somewhere in the pipeline. Disabling Windows acceleration and re-testing will tell you whether the acceleration is in the mouse hardware or in the OS.

Yes, this is a great compromise. Many competitive players use a separate gaming mouse with raw input for FPS games, and a different mouse or touchpad with acceleration for productivity and design work. If you only have one mouse, you can use mouse software profiles that switch DPI and acceleration settings based on which game or application is active. Logitech G Hub, Razer Synapse, and Corsair iCUE all support per-application profiles that can toggle acceleration on and off automatically.
