I play 1000 dpi, .62 ingame. I used to play 800 edpi, but switched for comp. Can't change sens since it will mes with my aim. Am I fucked? KZ wise.
You're fine for most things. Some jumps where you need a 360 bhop or a really fast turn might be difficult, but unless you're going for WR's I wouldn't change. I play 0.89 on 800 and make it work, although with a massive mousepad.
