The Ultimate Mouse Hunt
 

The performance of an optical mouse is difficult to analyze because numerous parameters come into play, and the results are always a compromise. Improving one performance factor doesn't necessarily lead to a better overall result. It's a little like what happens with cars. Wider tires with thinner treads will improve handling, but comfort and road grip under difficult conditions suffer. For an optical mouse, end performance is the result of a long, complex process that includes analysis of the surface, calculation of coordinates and transmission to the computer.
