noname one, thats not the point, the point is ur mouse is perfectlxy fine, set the ingame mouse sensitivity to 0, then adjust the cpi so u have the mousesensitivity in game u want, should be around 1000 cpi, then finetune ingame sensitivity if necessary, make shure mouseaccel is in windiws driver off and win sensitivity is set to 6, thats default setting

win settings u should do first, before u set ur mouse sensitivity

1000 cpi is for 24 inch monitor 1920X1080 rsolution, so u use nearest raw mouse input,
