So, we all know now that every DPI beyond a three-digit is a lie.
It's interpolated some way of another.

So, logically you must run native DPI to have the best tracking.
For example: its better to have 400dpi@4.0 sens than having 1600dpi@1.0 sens.

So the question is, where to get exact numbers?

And what to do with some mice like Abyssus 2014?
I have it and w/o synapse it runs at 1800 dpi, which is a lot.
What to do with this abyssus? Install synapse and force it to XXX?? (and what is native for aby 2k14?)
Or synapse still f_ks up tacking?
In that case I may get another mouse... I don't want f_ked up tracking.
