for all of those settings i would go to the maximum possible, except for thread priority i would put on highest but not \"realtime\".
i would also consider using Virtual Audio Cable if you are not already, for bouncing audio within the system. It doesn\'t degrade the audio quality like routing through your physical soundcard\'s codec often will. google it.
50% cpu use is FINE. at radioio with my own audio processing that i\'ve worked on for 11 years now, it uses 60% on 2.8gHz P4 HT, and i\'ve never had a problem with the system on any reguard... be it lack of CPU, or heat/stress. and those systems are 1U racks.
plus VNC uses at least 10-15% cpu on top of that, although we have set VNC to run on lowest priority so as not to interfere with anything.
if you are still getting glitches with XAP then, i suggest playing with the amount of buffers, and the size of the buffers. i\'ve found that multiples of 4 usually work best, for number of buffers. and size really depends on several factors, but really the only optimizing i\'ve had to do with those is when i\'m trying to get latency VERY low. so generally i would think you would want the size of the buffers maxed out. but you never know, so once you find which ammount of buffers is ideal (which could be more easily found if you turn down buffer size to the smallest)... i would just set buffer size to maximum since latency doesn\'t matter.
it is too bad they don\'t introduce ASIO to XAP though. i think it could be a formidable real-time audio processor if they ever decide to. especially with a few tweaks as seen in SAM4. the SoundSolutions in SAM4 are VERY low latency, close to none at all. unfortunately SAM4 doesn\'t do ASIO either.
