I can confirm, this was also the fix for me. Reinstalled the latest win update, turned Acc. GPU Scheduling back on, and uninstalled Dell SupportAssist. Side observation: The stutter got even worse, in duration and frequency, while running the SupportAssist's hardware tests (I thought I'd just give that a try prior to uninstalling it). The tests did not detect any malfunction.
Starting experiencing this problem around a week/week and a half ago, random stutter where my audio slightly cuts out something like a buzz sound, and my monitor skips a few frames. Absolutely no idea where this problem is coming from. I've ran the tests on SA (SupportAssist), as well as have run some windows tests. Anyone have this same problem? I've read that perhaps SA itself might be a problem and I might just uninstall to see if that fixes the problem.
Aurora R13, video stutter, audio stutter, SA?
