Stuttering can be caused by conflicting applications running in the background. For example Asus AI Suite and Asus Sonic Suite can cause tracking problems and need to be uninstalled. Apps that record or overlay the screen should be disabling, like MSI Afterburner, RivaTuner, F.lux, TeamViewer, etc. Some other apps can also be problematic like M-Audio. Hope that helps.
