Angle Snapping also known as angle prediction or mouse prediction. Is when your mouse with help of a algorithm will try to smooth out the raw input. By predicting you mouse movements it will create a series of straight lines. This is suppose to make doing simple tasks in a desktop environment a little bit easier. When it comes to gaming it actually results in a negative effect, missing out on crucial pixels and making you miss your shot.
Why Angle Snapping is Bad for Gaming.
Angle Snapping uses an algorithm that tries to predict the movement of your mouse to give it a straight line. Which you think might be great for tracking a player for a head shot. But if that player goes slightly up on a slope or moves a few pixels away from your cross hair. The Angle snapping algorithm won’t make a perfect representation within a few pixels of your hand movements. Throwing off you aim and allowing you to miss the shot.
When gaming, especially in a genre like FPS when precision is key. Using angle snapping is only going to have a negative impact on your performance. Now Angle snapping is only going to throw off your shot by a few pixels. If you are playing a game like CS: GO, this could be a difference between a headshot or being on the receiving end of one.
Now if you have been using Angle snapping without realizing it and adjusted to it. It might be fine for the average gamer, where precision by a few pixels doesn’t matter as much. But if you are trying to be competitive and playing games like CS: GO where pixel-perfect AWP shots are important I do recommend turning it off and playing for 20+ hours for your muscle memory to adjust to the new setting. Before deciding to use Angle snapping or not.
How to test if your mouse has Angle Snapping
If angle snapping is turned on then your mouse will be able to draw straight lines in programs like MS Paint. Simply draw a line with you from left to right. If your mouse shows straight lines then it is turned on. If your mouse shows variations and doesn’t keep a straight line then your mouse doesn’t have angle snapping. This is a feature that most modern mice might not have at all or won’t be set to default.
As you can see from the above image the red line show angle snapping off while the blue lines show angle snapping turned on. Without angle snapping your mouse should move in a wave-like pattern. As most people won’t be able to draw a perfectly straight line with just a movement of their mouse. When angle snapping is turned on you get a more rigid line if your movement is the angle of the line might move down a pixel to compensate. Like in the picture above.
