[QUOTE="Hazza06, post: 1270902, member: 163766"] UPDATE: i spent a small amount of time to re-produce the issue, collected the debug level logs, but then also reproduced the issue again this time with 'Keep MediaPortal always on top' option as disabled, and was able to bring sysinternals to foreground which showed media portal CPU utilization still low ( at around 4 to 5 % ) during video playback, sysinternals highlighted the CPU cycles consumed in interrupts. Really strange this one, the issue only ever occurs after a system resume from ACPI S3 sleep, and i've never had CPU cycles spent in interrupts before on this HTPC system, and i've been very careful about device driver updates. A dpc latency tool running during the CPU utilization in interrupts issue, shows latency to be rock solid low, like 40 to 50 mirco seconds.... I'll start disabling device x device until i find the culprit. [/QUOTE]
