So for some reason, despite knowing that lower in-game sensitivity is better for accuracy, it still took until yesterday to realize that the same goes for mouse dpi. I bring this up because last night I dropped my mouse setting from 2000 dpi to 1000 dpi and played a little in the practice range before going into quick play. Not only did I win a vast majority of my games, but my accuracy was pretty much always above-average by a significant margin (like +10%) along with eliminations. It could just be a coincidence combined with better matchmaking, but I like to believe otherwise.
