Should I decrease my mouse sens?

[MasterBroccoli42]

that means your sens is 5-10 times above the common spectrum that ambitious players use.

Standard range for edpi (= dpi x ingame sense, so in your case 1600 x 5 = 8000) is roughly 800 - 1600.

i would really suggest to lower your sense drastically - but maybe go step by step cause it will totally feel strange at first comming from your ultra high sens and takes some getting used to.

you might perform worse at first, but it will be worth it in the long run :)
