What Exactly is a Flawless Sensor

An ideal gaming mouse has a flawless sensor, it is devoid of flaws that introduce inaccuracy from your hand to the cursor in-game.

Flawed sensors introduce inconsistencies through errors in the sensor camera or processing of data through their controllers. There are a small handful of pronounced issues with flawed sensors.

Jitter

Jitter happens when the sensor is seeing a noisy signal, this results in a jumpy cursor on screen. 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.

Smoothing

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). 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.

Cursor Acceleration

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.

Acceleration 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. 

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. 

Prediction

Prediction helps aid nearly vertical or horizontal movements to present as perfectly straight on-screen. 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.

Axis Asymmetry

A good sensor should respond the same regardless of X axis (left/right) or Y axis (up/down) movement. Some sensors have flaws that make X axis movement slightly more sensitive than Y axis movement.

Resolution

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. 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.

Simply put, the higher the CPI, the more your mouse cursor moves every inch you move. Gamers have their own preferences to how sensitive they like their mouse cursor and there isn’t a best CPI setting. 

What is Polling Rate for a Mouse Sensor

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. Polling rate is measured in Hz, 1000 Hz means that the mouse is reporting to the computer 1000 times a second. 

A higher polling rate is always preferable for gamers, you want the most up-to-date mouse positioning data possible. Higher polling rates do use up more power, so a lower polling rate might be preferable if you’re trying to conserve battery life.

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.  There are gaming mice with higher polling rates, most notably the Razer Viper 8K, polling rates have significantly diminishing returns at beyond 1000 Hz.

Frame Rate or FPS

Frames 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. Similar to to polling rate, the higher the better here. The FPS of a sensor is usually several times higher than the polling rate.

FPS isn’t a strong indicator of mouse sensor performance. 

Inches per second

Inches per second is a measurement of tracking speed of the mouse, how much movement can a mouse sensor handle.

All sensors are rated by it’s maximum capacity and pretty much all modern sensors can handle movement well beyond what is physically capable of most gamers. 

If you move your mouse hand right to left 10 inches in 1 second, then that IPS is 10, most sensors are rated well above 150 IPS.

Max Acceleration

Not to be confused with sensor acceleration, max acceleration is a measurement of how much acceleration a mouse sensor can handle, this is measured in g’s. 

The mouse must be able to handle changes in direction and rapid movement from a stand still and track properly. Modern sensors are capable of what is well beyond physical capability now, but look for sensors with at least 20g acceleration. 

Lift off distance (LOD)

A measure of the sensor working distance from the surface, measured in mm.

Gamers who pick up the mouse often will want a lower LOD, you do not want the sensor to be scanning surfaces while the mouse is in the air, it is unwanted and unexpected movement.

Lift off distance preferences are subjective however, some sensors have customizable lift off distances, I would recommend trying different LODs to get a feel.

Ideal mouse surfaces

Optical mouse sensors will work on most opaque surfaces, tracking will work best on surfaces with uniform texture, whether that’s cloth, plastic, wood or metal. 

Optical sensors don’t work well on glass, the camera is not sensitive enough to track changes on glass. Laser is better for glass surfaces, a laser sensor is more sensitive, allowing it to pick up movement on glass.

Laser sensors have a trade off, higher sensitivity to surface changes often over reports movement on textured surfaces, causing jitter. If you have a glass desk, get a mouse pad and use an optical mouse.
