Some games let you even tweak strength of acceleration.Įxactly opposite behavior - faster your mouse is moving, less distance cursor will travel. This is the most common implementation and you can find it in Windows (under Enhance pointer precision) and in many games. Positive mouse acceleration means that faster you are moving your mouse, farther cursor will travel on the screen. There are two basic types of mouse acceleration: positive acceleration and negative acceleration. Usually when games use acceleration, the crosshair will end up on a vastly different location. If the crosshair ended up roughly on the same spot, the game does not feature acceleration.Now move the mouse back to the default position marked by the hand as fast as possible.This movement should take more than 2 seconds. Move the mouse slowly from the hand and create 90° or 180° rotation in-game.Put a hand on the mousepad on one side of the mouse to create a barrier.Move the crosshair to a specific spot - edge of a building, distant window etc.Mouse acceleration detection in FPS/TPS games Follow the guide below to find out whether a game uses acceleration: It is very easy to spot mouse acceleration in-game, as usually very fast mouse movement will result in several 360° rotations of the player's character. How to detect mouse acceleration in game Every game will have different acceleration setting and it is impossible to achieve any consistent behaviour. However it is highly undesirable in any game, where you are often in control of a camera. This behaviour can be beneficial in desktop environment where you'd need low speeds for precision task (image editing) and simultaneously fast speeds for quickly moving cursor to the different parts of the screen. With acceleration, if the mouse is moved by the same 5 cm but in 1 second, the cursor travels 1000 pixels - five times the distance of the slower movement. For example, a user moves their mouse 5 cm in 5 seconds and the cursor travels 200 pixels across the screen. Distance of the cursor on the screen is highly dependent on the speed which mouse is moved. Mouse acceleration is a different system to enhance mouse movement. Unfortunately is not easily detectable apart from mouse movement feeling weird. This feature should not exist today as every mouse on the market has at least 800 DPI resolution, however it is still used in some games and some mouse manufacturers are using it to further increase the perceived DPI. To prevent the jerky cursor movement mouse smoothing was introduced which allowed the system to interpolate raw data from the mouse and creating additional data points so the final mouse movement on the screen would be smoothed out. The technique was originally created for opto-mechanical mice (more commonly know as ball mice) as these mice did not have a very high resolution (usually up to 400 DPI) so cursor movement appeared jerky - the cursor jumped few pixels each time. Mouse smoothing is the interpolation of raw input data from the mouse in order to prevent jerky movement in low resolution mice. 3.2 Windows smooth mouse even if you disable pointer precision.2.2.3 Combination of positive and negative mouse acceleration.2.1 How to detect mouse acceleration in game.
