Query: Sluggish

I bought this item because of the price, and I needed a better mouse.This mouse is sluggish. I tried to tweak the software, but no dice.Maybe there's a time delay between the keyboard and the mouse, but I can't play some of my computer games -- especially Luxor2. The mouse acts like there's velcro on its bottom. It's OK for simple tasks, but terrible for response time.
