Got mine set to 0 too since anything more is just insantiy... though I have my mouse dpi sensitivity set at 3000 for swtor which isn't helping with that. Are you able to set the mouse dpi per game/program? If so, turning that down will help since you generally don't need to have it set so high for an mmo. I should probably turn mine down too lol.
