there's your problem, that's not what you know

High DPI is a marketing gimmick that has simply ballooned out of control in recent years in a mouse developer arms race. Back when all the optical mice were 400DPI and nothing else, there was merit for having higher DPI, but now that we are into the multi thousands its simply unnecessary.
People buy a new mouse and ignorantly crank up the DPI as they automatically assume its better, and they then proceed to compensate for that ridiculous DPI by cranking down sensitivity settings and/or their accuracy suffers as a result.
Some of the best professional gamers in the world use extremely low DPI and overall sensitivity, that fact alone should be enough to dispel the ridiculous "truth" that high DPI is better. Ultimately what every mouse owner should be doing is finding their own ideal DPI. Ignore trying to shoehorn the absolute upper end to work with what you use, and instead keep sensitivity settings stock and adjust the DPI until you are most comfortable.
