So my problem is that the mx518 at an usb refreshrate of 125 has terrible jitter/stutter while making small or minor movements (eg while trying to shaft someone, or small turns for ex.). The mouse is basicly new, and clean as a whistle (and does this on a random basis).

I have used multiple versions of setpoint, and must admit its pretty much trash, if I look at the negative accel issue ( the driver makes the mouse a bit slower, and I've tested it with 60cm/360 flicks that it's not precise, however if I ditch setpoint, the mouse is dead precise and performs outstandingly good.) Not to mention setpoint does not solve the issue. Things I've tried in_mouse -1,1,2, m_filter 1, 0 +available dpi settings. The rest of mouse preferences have not much incommon with this phenomen I suppose (might be wrong).

Alot of experienced players stated use 500 hz you will be pro, etc etc, but its a matter of what you're used to.

specs: SteelSeries QcK+ (450x400x2mm), Win7 ultimate (drivers up to date)
