SA and Command Center are two pieces of software that can cause various problems for some users.
Removing most of Dell programs like SA (SupportAssist) help fix my stuttering problems. I'm still under warranty a Dell tech try to help fix my pc but never found this issue. I figured it out myself by just getting rid of a few apps also looks like they want to help me re-install support assist but I try that already the stutters return. Had no choice but to remove it. Wished it work.
