You made sense until you mention DPI.
I game between 800-1200 DPI and have been accused of cheating for my sniping skills in games like Enemy Territory and Battlefield. Go above 1600 DPI and mouse movement is simply uncontrollable for me, even for desktop use.
High DPI being better or 'smoother' is simply a user feel issue, not a law of mouse use.
Yes it is a law of mouse use. Lets say you use 800DPI and your mouse performs the same at 3200. Use 3/11 to compensate on the desktop and divide your ingame sensitivity by 4. The sensitivity on a general sense will stay the same but you will gain a decent amount of precision.
Marketing DPI became taboo inside the competitive gaming scene for different reasons and as such, most people choose to ignore it even though there are real gains to be had.
Ben90: How can you explain Rapha wining Quakecon 2013 with a Wheel Mouse Optical? 400 DPI and less than 2 m/s perfect control speed. I would rather use a mouse with a perfect sensor because for sensitivities between 10 cm per 360
and 30 cm per 360 you don't really need DPI higher than 800 or control speed greater than 2 m/s.
Rapha is probably the best example of why you don't need perfect mouse movement.
For starters, Rapha uses large amounts of acceleration. By doing this he not only acknowledges 1:1 isn't necessary, he prefers a so called
flawed setup. Most Quake pros use acceleration. I'll agree that software acceleration is cleaner than hardware but it's no secret Rapha isn't known as an aim player. In my opinion, Strenx and Evil are the people we should be looking at with their absolutely insane shaft. Out of pure luck to my point, they both use mice with angle snapping and prediction.
Rapha wins games because he is smart, there are countless anonymous people playing Call of Duty that can aim better than him. Most professional athletes don't need the best equipment to win, although it can definitely help.
While I know it sounds contradictory, I still want my mouse to have the most 1:1 sensor possible. I was just showing how little it actually matters. For what it's worth, I tried playing "russian style" and decided to leave that to Rapha.
