To be honest, I’d drop your mouse to it’s native DPI (usually waaaaaay lower than the max DPI) because the hardware sensor upscaling can be unreliable at times. From there, play with your ingame sensitivity.
Also, play with what you’re comfortable with. Personally, I play where a wipe to the left or right is roughly 100 degrees. I used to go a lot lower with EDPI when I played CS, the kind where you need a big mouse pad and mostly shoulder pivot instead of wrist pivot. Pro tip: it’s absolutely terrible for your shoulder.
