The higher the DPI, the higher the sensitivity and vice versa.
DPI means «Dots Per Inch«, which translated into Spanish would be «Points Per Inch», is a term closely associated with technology, since it covers many aspects, from the number of pixels that the mouse cursor can move within a inch, up to the number of dots a printer can print in one square inch.
If we talk specifically about the DPI in Game, the DPI is the exact number of pixels that will be displayed in one inch of space on our screen. The difference between a greater or lesser amount of DPI is that the more points there are in a space, the density of these will be greater and the same in the opposite direction. The higher the DPI, the higher the sensitivity and vice versa.
