Optical is more accurate than laser. Higher DPI is always better. Acceleration is the devil. Wireless mice are laggier than wired. Your Windows mouse sensitivity setting must be set to 6. If you understand any of that, chances are you’ve spent some time reading about gaming mice, trying to figure out what actually matters in a gaming mouse.
When I wrote about the best gaming mice, I explained how I tested them and defined some key terms like jitter, acceleration, and CPI (counts per inch, a more accurate descriptor than DPI). But defining those terms is just scratching the surface—there are lengthy, extremely detailed articles and forum posts about the minutia of gaming mice online, many of which are filled with outdated information, techno-voodoo and internet folklore. To separate out the fact from the fiction, I talked to François Morier, a senior engineer at Logitech for 15 years. And in this case, ‘senior engineer’ is a bit of an understatement: when it comes to designing mouse sensors, Morier is The Guy at Logitech. He knows more about mouse sensors than just about anyone else on the planet.
From my interviews with Morier and Chris Pate, the senior product manager of Logitech’s gaming division, I’ve tried to address some of the most confusing elements of gaming mouse technology, and correct some of the most common misconceptions.
