![]() Similar to to polling rate, the higher the better here. Frame Rate or FPSįrames per second or framerate in the context of a mouse sensor refers to the number of frames, pictures, that the sensor camera captures in a second. There are gaming mice with higher polling rates, most notably the Razer Viper 8K, polling rates have significantly diminishing returns at beyond 1000 Hz. Most gaming mice and sensors are capable of 1000 Hz polling rate and that is more than enough for gaming, some competitive esports players still play with 500 Hz mice. Higher polling rates do use up more power, so a lower polling rate might be preferable if you’re trying to conserve battery life. Polling rate is measured in Hz, 1000 Hz means that the mouse is reporting to the computer 1000 times a second.Ī higher polling rate is always preferable for gamers, you want the most up-to-date mouse positioning data possible. The polling rate is in reference to how fast the mouse updates the computer with new information, not to be confused with capture frame rate of a mouse sensor. Gamers have their own preferences to how sensitive they like their mouse cursor and there isn’t a best CPI setting. Simply put, the higher the CPI, the more your mouse cursor moves every inch you move. The correct term is counts per inch (CPI), how much does the sensor report movement per inch of physical movement, but is commonly called dots per inch (DPI), which is incorrect, but works the same. Resolution is the rating of how sensitive a mouse sensor is to physical movement, this is represented in counts per inch or dots per inch. Some sensors have flaws that make X axis movement slightly more sensitive than Y axis movement. Axis AsymmetryĪ good sensor should respond the same regardless of X axis (left/right) or Y axis (up/down) movement. This might be useful for certain drawing or drafting applications, but completely unwelcome in gaming where matching hand movement with on-screen is necessary for precise gameplay. Prediction helps aid nearly vertical or horizontal movements to present as perfectly straight on-screen. Some gamers do prefer acceleration and introduce it via software, but to have acceleration built into the sensor of a mouse is something that cannot be worked around once it’s in. Most gamers prefer a 1:1 input from hand to cursor, meaning the speed at which the cursor moves should equal the speed at which your hand moves on the mouse, this predictability produces stronger muscle memory and better performance for gamers over time.Īcceleration changes this 1:1 ratio when speeds pass a certain threshold, the initial purpose of acceleration was to prevent fatigue from moving the mouse cursor from one side of the screen to the opposite site, potentially handy for productivity, harmful for repeatable gaming performance. Smoothing happens when a mouse sensor averages out the two captures instead of sharing the latest position, resulting in a more delayed response on-screen to hand movement. Mouse sensors capture more images than it reports to the computer, for example, a mouse sensor might have an FPS capture of 2000, while it only reports 1000 times per second (1000 Hz). Laser sensors are especially prone to this because of its sharper laser cameras, it detects a difference in mouse pad material and reflects that on screen, resulting in a jumpier cursor than optical sensors. Jitter happens when the sensor is seeing a noisy signal, this results in a jumpy cursor on screen. There are a small handful of pronounced issues with flawed sensors. The most popular sensor, seen on all wired Glorious MiceĪn ideal gaming mouse has a flawless sensor, it is devoid of flaws that introduce inaccuracy from your hand to the cursor in-game.įlawed sensors introduce inconsistencies through errors in the sensor camera or processing of data through their controllers. ![]() Razer Viper V2 Pro, Razer DeathAdder V3 Pro Here’s a list of known flawless mouse sensors on the market today. ![]()
