Turning off mouse acceleration requires a system operation. Windows users should enter the control panel → Mouse Settings → Pointer Options, uncheck "Improve pointer accuracy", and optimize with third-party tools; Mac users cannot turn it off completely, but can adjust the curve through Karabiner-Elements or use the driver to customize the settings; in the game, relevant options need to be turned off in the settings and add startup parameters; in the peripheral driver, the enhancement function must also be turned off and the DPI value must be fixed.

Mouse acceleration is a "invisible killer" when many people play games or do fine operations. If you want your mouse to move more stably and predictably, the first step is to turn off the mouse acceleration function in the system . Different operating systems and devices have slightly different settings. The following are several common situations to explain clearly how to adjust them.

How to turn off mouse acceleration on Windows

Mouse acceleration is enabled by default, which means that your mouse movement speed will automatically adjust according to your hand speed, which will greatly affect the feel when playing games or designing.

The operation steps are as follows:

• Open Control Panel > Mouse Settings
• Switch to the Pointer Options tab
• Check the item "Improve pointer accuracy" and the default is the check state, which means that mouse acceleration is enabled.
• Uncheck it and click OK to save the settings

Note: This setting simply turns off "Enhanced Pointer Precision" and does not mean that all forms of mouse acceleration are completely turned off, as some drivers or graphics card software may have additional processing.

If you have high mouse requirements, you can use third-party tools such as x-mouse tuner or mousefix to further optimize.

Do Mac users care about mouse acceleration?

The Mac system itself does not have a clear "mouse acceleration switch", but the mouse behavior of macOS is essentially equipped with an acceleration curve. That is, the faster you slide, the farther the cursor moves.

There is currently no official switch to turn it off completely, but it can be mitigated by:

• Customize mouse sensitivity curves using third-party tools such as Karabiner-Elements
• Adjust the "Track Speed" slider in the system to find a point that you think is more linear

If you use Razer, Logitech and other brands, their supporting drivers sometimes provide custom curve functions, you can try it.

How to turn off mouse acceleration in the game

Many FPS games (such as CS:GO, Valorant) have their own mouse settings built into them. Even if you turn off acceleration in the system, you may still have a set of logic in the game.

So suggestion:

• Go to game settings → control → mouse related settings
• Find out if there are options like "mouse acceleration", "enhanced pointer precision"
• Turn off all of these
• Some games also support forced shutdown of startup parameters, such as CS:GO plus -noforcemaccel parameter

Doing this ensures that your mouse movement is "1:1" feedback during the game, and the feel is more consistent.

Don't ignore peripheral driver settings

Some high-end mouse comes with drivers, such as Logitech G Hub, Razer Synapse, SteelSeries GG, etc., often have their own options for adjusting mouse sensitivity or even "enhancing performance".

suggestion:

• Open the corresponding driver software
• Check if there are options like "Enhance pointer precision" and "Smooth Mouse Movement"
• Turn off these functions uniformly
• Set DPI fixed value, do not use automatic DPI switching function

If you don't pay attention to these details, even if the system and the game are closed, you will still feel "suspected acceleration" in the actual experience.

Basically that's it. Although it doesn't seem complicated, it is easy to miss a certain layer of settings, resulting in the effect being worse than expected. Check it step by step and make the mouse more "obedient".
