So I have been playing for a short time now, and I started to notice that I can easily keep up with fast maps, problem is my mouse can't, it seems whenever I move it fast it tends to get squarish movements, and at the worst times it will just stop moving all together and sometimes even go backwards from where I was moving, I started thinking it was my computer being laggy with the way it handles mouse movement, so I tried a new mouse, it was fine, just too uncomfortable to use XD so the question, is a 2004 mouse at 800 dpi to old? if anyone has a recommendation on what to do it would be greatly appreciated.
