@Aksel Well, it depends on what games you play and how fast you want to be. For example, I like my DPI to be around 5000 when I'm playing DOOM, and around 3700 when I'm playing StarCraft II. But yeah, I agree that certain levels of DPI aren't necessary, I mean who's gonna use 16000 lmao
Also, agreed on testing the mouse for yourself and see what's the best fit for you
