Same from me, Jack, I have theories, but I’ll keep them to myself. I just wish you good luck. Rudy, Rudy, Rudy, I mean Jack, Jack!
Anecdotally, I had something that was going every 10 minutes, would hit the fps counter hard, and buzz static on the speakers. I have since been using something called “Game Mode” on my system app Killer Networking, which ends unneeded processes and the 10 minute anomaly is gone.
Best wishes!
