Having issues with low FPS on CSGO after the updates that were installed on my PC (03/09/2016 UK date). I'm getting around 20FPS on the main menu screen and around 24-30FPS in game- when usually im getting around 125FPS+. I have used powershell to get rid the xbox thing- though the little green window asking me the press windows key and "G" still pops up. I have also tried uninstalling the new updates to little success, can anyone help me? I haven't tried any other games yet.
