i have a couple questions about my G5, and just mice in general for that matter. first of all i noticed i can change the report rate from 125-1000, currently i have it set at 500. what will changing this do and will it help me out with anything? will i notice a difference? also a question about DPI; does increasing it to like 2000 make a difference in anyway as opposed to 800? like would i be better playing with a lower sensitivty and higher DPI? or would it make no difference. thanks for any input.
