For me I find the high DPI of gaming mice to be annoying more than helpful.
What does that mean? I know what DPI means, but I don't know how high-DPI mice feel different from low-DPI mice.
I don't even know if I've ever used a high-DPI mouse. All the ones I've ever bought home have been the cheaper ones, like 2x Logitech M325 today, 9.90€ wireless mouse (using one now).
Then again, I wouldn't be surprised that some of the mice I've gotten from work are some pricier high-end mice (because they came with some high-priced corporate laptop), but I can't really tell whether they feel different compared to my cheapo mice. The only thing that usually catches my attention is how the scroll wheel feels, e.g. in some mice it is quite coarse and loud, while e.g. in these M325s it is very nice, silent and smooth. The scroll-wheel even has inertia in M325, a bit like a trackball does!
And as I revealed, for some reason I don't seem to break mice down that often either, cheap or expensive.
EDIT: This Logitech M325 feels a bit odd... different to what I'm used to with my other mice. I wonder if it is that "mouse acceleration" that I sometimes keep hearing? It definitely feels like sometimes I lose track of the mouse pointer as it has suddenly travelled much faster than I thought the flick of my hand should move it.
But then maybe it is just a matter of learning it, because in theory it sounds good that it can be both precise and fast at the same time.
