At least I'm not going mad. I didn't think it was doing anything but it's somewhat subjective. Any thoughts on the wakeup watermark though? It seems that whenever there is a glitch, the watermark is increased, and whenever the watermark is increased, the frequency of glitching increases until it hits the limit - in my case 71.27ms. Is there anyway to force this wakeup watermark setting? Everything works better for me, although still not perfect, when it is a low number. Chris.
