Calibrate FPS Aim Sensitivity Using a Mousepad and Marker
Most first or third person shooter games on PC handle sensitivity with a numerical setting, changing how fast your aim changes on-screen based on how far the mouse is moved on a table. A big problem with playing more than one game of the type is that it’s difficult to switch between multiple games without losing aim accuracy, as the mouse sensitivity value is handled differently for all games. So how would you make the ratio between rate of movement on-screen and the rate of movement of the mouse the same for all games? Using an old mousepad, a sharpie, and a ruler, we figured out a way to ‘calibrate’ games so that they would all have the same sensitivity.
Important: Before you begin, make sure to turn mouse acceleration off, which is a setting found in the Windows control panel. Mouse acceleration changes the speed of the cursor depending on how fast the mouse moves, and we want to have the same amount of movement on-screen with the movement of the mouse at all times without speed as a factor.
The way this works is that we’re going to measure the distance that the mouse needs to move in order to complete a 360 degree spin in-game, and then tweak the sensitivity of other games so they’ll also use the same distance. Boot up your favorite game (preferably a first person shooter to make bullet holes), the one that you’re most comfortable aiming with. Facing a wall, place your mouse as far left to the mousepad as you can with the surface of the mouse completely over the mousepad. Make a marking on the wall (fire a few shots) to indicate where you started, and then using a permanent marker, draw an outline of your mouse on the trackpad.
Drag your mouse straight to the right, spinning your character, until your on-screen crosshairs return to the marking on the wall for a full 360 degree rotation. Let go of your mouse, leaving it where it is, and using the marker, draw another outline of your mouse where it is now. At this point, there should be two outlines of your mouse drawn on your mousepad, far enough apart to complete a 360 degree spin in-game. Try it out!
Now whenever you launch a different game, whip out your newly created calibration mousepad and perform the same process – except this time, instead of drawing more lines on your mousepad, change the sensitivity setting to match a complete spin moving the mouse the same distance as before, as indicated on the mousepad.
