Steelseries Sensei - Jumpy mouse cursor.

[ItsTorolla]

So, I recently bought a steelseries sensei mouse who I been a huge fan of. 
But recently I have been missing all my shots in CS GO and when I usually play at least one hour a day I started asking the question, wtf is going on. 
So I started practicing more. Then changing dpi and stuff like that. Then the resolution and so on. Then I was convinced it was my mouse pad. 
But whatever I did, I still missed those shots. 
So I ended up trying to draw a straight line in paint and there I got my problem.

Now I have basically tried everything I can think of, but nothing is helping. Driver reinstall, firmware update, changing up the usb port and so on. 
Changing to a simple (but crap) dell mouse lets me draw a straight line.
So now i'm kinda wondering, is the mouse is broken/defect?
Is there anything I might have missed? 
Or is it supposed to be like this?

The drawing is awesome I meant it.
