have you checked the wan drivers ? Idk, I have never experienced anything like that. I am playing a lot of CS GO and everything is fine. I am sure that there is a software problem, maybe you should reinstall the drivers. By the way, when you will solve that problem, we could play together a couple of games. If you have a very low rank it's not a problem, you can always use a rank boosting service like eloboss.net. If you are interested, leave me a message! It's going to be really cool! I am waiting for your message, dude!
