Latency in Vegas 6 - what's reasonable and ho

I'm doing more and more complicated surround mixes in Sony Vegas 6 -
10ms latency tends to break up with more than around 10-15 stereo
tracks playing back, especially with video playing back at the same
time. Reducing to 100 - 200 ms gets me 20-25 tracks of playback but
make it tough to judge price edit point.

Is this normal performance for a system like mine? What would be the
best strategy for improving performance?

Why are you talking about latency in the same breath as "mixing" ? If you are running out of CPU with that number of tracks, increase the buffer size. Yeah, the latency will increase, but it's not a factor at all, unless you are actually tracking while you mix !

Or maybe your editing criteria is a *lot* sharper than mine.

I'm assuming that if you increase the buffer while editing and mixing to the image, Vegas DOES NOT slow the image playback to match the increased buffer. At least that's how I'm understanding it.

If you are punching in audio, e.g. ADR, it does not compensate picture delay to match your latency settings.

weird, it sure as hell compensates for audio latency between the playback and record, or we wouldnt even be using it EVER...then again I dont monitor thru it so could be something to this, Ill do a test

I could be wrong - and I am monitoring out to firewire...
