What I'm trying to say is, though it might not be 100% accurate, in most cases optical mice perform better on soft pads whereas laser mice only perform (truly) well on hard surfaces.YayMii wrote:
Well, according to Steelseries themselves, the QcK series is designed for optical while the HD series is designed for laser.
I am not sure if optical mice perform much worse on a hard pad, but it's probably not an ideal combination to say the least. Laser mice + soft pads = just plain bad unless there is an exception of which I'm an unaware.
