which Steelseries and which Artisan?
did you clean out the lens?
G502 does not jitter on those settings at all for me, on various mousepads. QPad UC-50 v2 Pro, Steelseries QcK Heavy, Artisan Hayate Otsu, Fnatic Gear Focus D1, fUnc F30.R... or my custom glass mousepad, which is satin frosted glass.
is anyone using g502 here? do you guys feel like the mouse twitches sometimes?
that list says it jitters over 2000dpi.
Seriously?
I should look in to this. Maybe I'm stuck with random mice brands like Sentey
Edit - Hmmm.. maybe jittery is a good thing?
higher dpi naturally causes jitter..
But the important thing is, the pixart processes all dpi natively...
I do my websurfing and other causal computer use at 6,000-7,200 dpi.. I've never noticed a difference when I switch down to 3,200-1,600 dpi for other stuff..
jitter is not a good thing

it means it's picking up things that aren't what you're actually trying to do. some people just aren't sensitive to jitter due to not needing pixel precision.
