I’ve built several AMD systems over the past 20 years, and until now all the ones with nvidia GPUs were absolutely rock solid wrt hardware. The Radeon builds suffered various mostly minor GPU driver problems. But son of a bitcoin, my current PC has this exact stuttering problem! And all this time I just assumed it was Windows being stupid about normal I/O. But come to think of it, I did recently have a conversation with my even-hardware-geekier brother in which I said something like “How in the hell can Windows have become so sloppy that the mouse cursor can be regularly interrupted during normal use? That should be logically impossible by design.” But now I bet it’s this motherboard thing preempting everything and it all makes sense.
