(i.e. DPI) that is regarded as highly important for those who do not know any better instead of using quality optical sensors that give 1:1 tracking without any of that acceleration/prediction/z-axis issue garbage.
I wish gaming mice were driven by actual performance - not releasing new mice for the sole purpose of having a larger number on the box. There are incredibly few mice that have perfect sensors. Even if they have perfect sensors, they suffer from some other issue such as bad ergonomics, bad build quality, or problems with cheap cables.
According to the calculator here (http://www.funender.com/quake/mouse/index.html
), using my current horizontal resolution of 1920 pixels at FOV 90, with a turning rate of 2 inches per 360 degree turn (I loathe turning rates any longer than that), I would want a 3015 DPI mouse.
Now, lets look at a different situation. Let's say I'm playing Skyrim and I don't actually mind the skinny default FOV (65), and since this is more of an exploring gametype, I might want to look around a little faster than usual, so I might use a turning rate of 1.5 inches per 360, and let's say I acquired a 2560x1440 monitor. All of a sudden my minimum DPI is 8416, which is only almost reached by the newest sensors available.
And then you have the 4Kx2K monitors which should be coming out soon (I hope). Increasing the horizontal resolution to 4096 while leaving all the other settings the same, I would need 13,465 DPI.
These are not "useless nubers", you are getting increased accuracy with each increase in DPI, and that actually still applies regardless of screen resolution.
If you start up TF2 and set the resolution to 640x480 in windowed mode, and then set the mouse sensitivity all the way down, you will see that there is a lot of room for aiming within the range of each pixel (yes, you can shoot at different spots without moving the crosshair).
Note that your view does not remain entirely static while you aim within the same pixel, things in your peripheral shift around, and even at 640x480 they do so more smoothly with increased DPI (given the same turning rate).
This may not be of huge practical benefit, but with some AA and decently high resolution, you're not really aiming at an individual pixel so much as aiming at an approximate spot anyway. Throw in a healthy amount of familiarity with your turning speed and I don't doubt that people would hit things more precisely using higher DPI, even without any change in screen resolution.
At the same time, I am just as annoyed as anyone else that all the new sensors nowdays have some sort of acceleration or other effect that interferes with your ability to aim reliably.
Whether or not extra DPI is worth the tradeoff in sensor quality you get with something like the Razer Abyssus is a good question (the Abyssus is one of three mice currently produced which have a perfect sensor).
