Maybe your settings are too high, I only get jittery touch controllers happening if I've tweaked my settings too high.
I'd like to know about the smoothing setting myself, because I can notice it and want to turn it off. 
Maybe it's in OVR advanced settings if you install that on Steam. you access it through your dashboard in the headset, in in fact I'm sure I saw a smoothing setting in there when I looked through what settings I could tweak.
