Hi Alex,
Mouse acceleration can indeed hinder the ability to play games where you need precise aim because it causes your mouse to move not only based on movement, but also on speed. You can disable mouse acceleration by following the steps below:
- Click Start.
- On the search bar, type Control Panel and select Control Panel in the results.
- If you are in Category view, click Hardware and Sound.
- Under Devices and Printers, click Mouse to open the Mouse Properties window
- Click the Pointer Option s tab, and uncheck the box next to Enhance pointer precision.
- Click Apply, then OK.
If you need further assistance, please do not hesitate to post a reply.
