Mouse is Unresponsive, Is it broken?

[Arsenal221]

I have been consistently using a Redragon Centrophorus mouse for the past year. I just got onto my computer earlier, and it seems to me that the mouse is having a much slower response time. When I move the cursor along a straight line, it appears to skip and lag behind. What could be the possible issues?

Thanks!

Your mouse has 4 DPI (dots per inch) settings, 800/1600/2400/3200. This determines how fast the the mouse cursor moves across the screen. The DPI is controlled by pushing the button behind the scroll wheel. Each push changes the DPI, so you can pick the DPI setting that feels best to you.
