I've been using the razer deathadder 2013 for a little less than a year now and i have never had any problems with it until now. When I'm playing a game my mouse will move at its correct speed when i look one way but move super fast when i look the other way. An example is when I'm playing CS:GO my mouse will glitch and when i look left it will take half a mousepad to turn 180 degrees but when i look right it will take half a mousepad to turn 360+ degrees. When using my mouse in google chrome it performs at the correct speed it should be. I've asked friends and they told me to check to see if i had mouse acceleration on. I checked razer synapse, windows settings, and the games settings and nothing had mouse acceleration enabled. I'm thinking i might need a new mouse.What do you guys think? Thanks for taking the time to read.
