In my case, SC2 is the most important determining factor. I tend to have a fixed wrist but I'm experimenting with the 1:1 ratio right now (no enhanced pointer precision, accelaration reg fix, 6/11 in Windows and 51% in the game). Thus I can't make my whiz moves any more but my overall accuracy may be improving and at any rate I do feel I have more control of the pointer now. Apparently, the mouse dpi setting makes much less difference now than it did with accelaration on. Much lower dpis are now playable than used to be, although still not ideal. Using either 2400 or 3200 (anything > 1600 on my mouse is interpolated, though). I can set dpi manually to 1920*1080 but regular 2400 or 3200 seems better.
To put things pragmatically, what I want to get is:
— sensor always awake,
— no over or under-shooting,
— good ability to micro units, including small units (at work: hit the exact character to begin highlighting),
— no mouse slipping from my hand,
— no numbing pains, stiffening etc. that harm control in addition to simply causing pain (which is not as bad as the thought of what damage is being done and what stuff's going to look like in 30 years from now).
At the end of the day I don't care whatever parameters that mouse has (but preferably no Microsoft or Razer logo). It can be a ball mouse if it does the job. (In fact, it'd be preferred if only it could because I've used ball mice most of my PC life.
)
The bad thing is I have to make my decision without being able to take it in my hand and try. In this city you just can't, except for the typical galore of office mice and occasional 518 from Logitech but no gaming stuff. This is why I'm so undecided and overanalysing stuff all the time. I can afford a gaming mouse but I can't afford five of them.
