The three most important parameters that determine mouse performance:
1. Sampling rate
There have always been two versions of the mouse sampling rate, DPI and CPI. More intuitively, it reflects the mouse's sensitivity. DPI (Dots Per Inch) is the number of pixels Per Inch, while CPI (Counts Per Inch) is the number of Counts Per Inch. In principle, the latter is the measure of mouse performance, which refers to the number of instructions the mouse sends back to the computer for every inch of movement on the surface. However, the definition of DPI by mouse manufacturers is not a classic definition, but refers to "the number of points corresponding to the movement of each displacement signal", which means that the DPI in the mouse manufacturer's mouth is actually equivalent to CPI. Therefore, the two abbreviations can be regarded as synonyms.
Currently, the higher the DPI is, the more expensive the mouse is, but the higher the DPI mouse is, the less it can perform on a low-resolution display. 1000 dpi mouse, for example, when the mouse move an inch distance on the surface of the table (25.4 mm) metric, the cursor can move 1000 pixels on the screen, the user screen resolution is 1920 by 1080, if the user needs to move on the surface of the table 2 inches (51 mm), you can move the mouse from the far left of the screen to the right.
If you want a fancy mouse to perform as well as it should, you'll need a 4K or 8K display.
2. Rate of return.
The rate of return is the value of the mouse MCU (micro-control unit), which returns the signal to the host machine after it has been processed. Its unit is Hz. For example, if the rate of return is 125Hz, it can be simply assumed that MCU sends data to the computer every 8ms. 500Hz is sent every 2ms. The rate of return is a mouse performance parameter that gamers attach great importance to. Theoretically, a higher rate of return can bring the mouse performance into full play. It is more practical for gamers.
3. Refresh rate.
Refresh rate is the parameter value that the mouse's optical engine feeds back to the mouse MCU (micro-control unit) in FPS (frame/second). By definition, it refers to the number of images taken per second by the mouse's CMOS imaging chip, which in common parlance means the number of times the mouse's optical engine takes pictures of the bottom connection of the mouse within a second. For example, a conventional mouse can sample up to 3,000 frames per second, which means it can sample and process 3,000 shadow images in one second. The mouse with high refresh rate can protect the mouse from losing frames at high speed.
After reading this article, I believe that you have a certain understanding of photoelectricity and laser engines. We then dropped to the three main parameters to focus on when selecting a mouse. Of course, the grip must be considered before spelling the parameters. A mouse performance again strong, the grip is not good, also like chicken ribs, tasteless food, abandoned pity.
