ahzrukhal Run your hardware as high as you can
optical and laser mice use hardware tricks that makes the software think it can go above the native DPI, which makes an optical mouse extremly inaccurate and a laser very inconsistent in acceleration which is the problem OP's having because he's used to the weird inaccuracy of the mouse, so please don't do this, just go with native DPI
if you want to know more about the hardware trick watch this for ~3 minutes https://youtu.be/lc7JVjcPzL0?t=1m29s and you'll find out it's completly bullshit and impossible to raise DPI while maintaining performance
