There are 3 way you can be
better at aiming with a mouse:
Disable acceleration (enhanced pointer precision)
Lower your sensitivity
Use a lighter mouse
Past that, it’s practice, practice and more practice. If you only recently moved over to M+KB, you haven’t developed the muscle memory. Start with games that just require you to click on things, like Civ games or Stardew Valley, and games that don’t require rapid movements, like Portal.
