How do I check my mouse's DPI?

[ImperialFalcon]

I got a cheap mouse from eBay. It is an Arco2 E-Blue. Is there any way to check its DPI?

control panel > mouse > pointer options.

If you have been using mouse acceleration and that is what you have grown accustomed to I can't stress enough that you should turn it off. you'll take some time adjusting but the pros are worth it.

mouse accel off and 900 dpi is what I and most fps or gamers in general use, even if you don't game it will give you an accurate pointer.
