I'll be more specific by stating my DPI and in-game mouse sensitivity.
My DPI is at 2000, as I like to be able to quickly and efficiently loot chests with just a small stroke of the mouse.
My in-game sensitivity is at 45%, as I like to be accurate with swift motions across my entire mousepad. I frequently pick up my mouse to prevent it from reaching the edge of my mousepad, but it's definitely worth it. It's personally my perfect sensitivity, and I recommend trying it.
