Why you are not allowed to take aim, in fact the mouse role big…
Saturday, May 5th, 2012By night and listen to what is building the DPI mouse? DPI is dots per inch,also is the mouse every move an inch pointer in the screen points. Such as 400DPI mouse, he in mobile an inch, the screen Pointers that can move 400 points.In fact this concept also not DPI more accurate only said the precision of themouse. For example, the dots per inch “dot”, on the screen and not constant.His resolution by the influence of factors, so it is not the only correspondingscreen pixels. May this point is 4 pixels, may also is 1 pixel. This is becausein the concept of DPI to be the change of the display. At present more scienceand by the new standard is recognized with CPI to show the mouse accuracy. Thiskind of the interpretation of the concept is: every inch the mouse samplingfrequency. Understand speaking, is the mouse moves an inch, mouse can move onfrom surface acquisition to how many points of change. The attribute of themouse to completely for performance, no longer involved in the monitor. So, wecan be more accurate, constant reflect the mouse accuracy. But since mostcurrent mouse manufacturers have had to adapt to the DPI way to address. So thecurrent production links most still continue DPI index presentation. When weneed a mouse in the screen a fixed distance, high DPI by moving the mouse,physical distance than low DPI mouse to short. The former can be more smalloperation of the fastest time in response. This point in FPS games is veryimportant. Master in order to pursue the shooting of maximum stability, willusually be the mouse speed the default value is relatively low. When need tosuddenly whirled around, 400 DPI than CPI multi-purpose a times to 800 physicaldisplacement, thus easy to will immediately killed the enemy’s chance to miss.Maybe you will ask, speed up the mouse on a big some can not solve the problem?Yes, that’s correct. Although the physical mobile distance shortened, but theloss is the precision of the positioning. If the mouse physical pointscorresponding to the screen logic point, had a physical point and a logicalpoint corresponds, in the open under the influence of acceleration, to keep upwith the mouse pointer movement speed, can will be part of physical pointignored. Then becomes a physical point may be more logical point corresponding,precision natural was reduced. So the advantage of high DPI embodied in theinstant speed up at the same time can provide nearly perfect accuracy, and lowCPI mouse is in any case can not do this. If you are a high requirement of themouse the FPS player, choose a high DPI mouse is needed. If want to give DPIaccuracy is defined as words, so in fast moving, high DPI accuracy of the mousemust be greater than the low DPI mouse. But the mouse CPI also was not static,it won’t keep up to 800 DPI index. When the mouse movement speed is slow, atthis time the value of the DPI will change the very low. When movement speed,DPI values may subsequently heighten. That is CPI and mouse movement speedbecome direct ratio. All this is by optical sensor movement speed to makeaccurate judgment. So, the discretion of the DPI for drawing no significancefor field basically, but in the fierce FPS games, high DPI will undoubtedlybring you more of a dog person.
