Ok lets settle this once and for all.
It is just driving me nutz, I was trying to make a selection in photoshop but the thing jitters as soon as it's not perfectly aligned to pad and I have to do it again and again. Or when browsing and trying to click a smaller link. Never had problems like that with even 5$ mouses.

I am thinking of trying to take it back under warranty but I dont know know it they will accept that or say ah its fine. And If I get a new one I'm afraid it would be the same as current.

I think they are all flawed.
If you have a pic of a mouse working under all conditions post a pic to prove it and settings you use.

Model: LOL edition RZ01-0036
Mousepad: goliathus speed
Driver: no drivers installed (i have noticed that its smoother with it but feels less responsive in quake like there is some processing involved)

I have some a4tech mouses that work flawlessly with no issues, abyssus just feels like a rodeo bull sometimes, you never know when it will jitter and fuck with you.
