I own a SteelSeries Ikari gaming mouse; it's one of those that are extremely, extremely sensitive. (There's a screen at the bottom of the mouse that allows you to adjust the sensitivity) Regardless of the setting, I seem to come across an issue: the mouse twitches a lot. It does not happen while the mouse is stationary, but when navigating the pointer or drawing in Photoshop, perhaps, it's an absolute wreck. The issue was present on my last computer too, so that eliminates the possibility of it being misconfigured on my computer or whatever. It is quite irregular. I've tried to use a Q-tip to dig into the optical sensor a little and just try to softly clean it in case small hairs got caught in there, but that didn't help. Advice? Anyone might know why this is happening? Thanks in advance.
