I've been pretty curious about this. We seem divided over this, some love it and some hate it. Here's what I have found.
It can work very, very well. I put a HQ EX clips onto the V9 T/L. Plays out nicely, add CK FX and switch on adaptive preview. Quality drops but fps holds up. I added a similar clip minus any FX after it. Kind of wierd watching the quality jump up after the cut but what else could Vegas do here.
So I started adding more tracks and clips, all composited via CKs. Now things gets messy. Vegas is forced to spend a lot of time decoding the source mpeg streams. The adaptive preview seems to get muddled and frame rate jumps up and down. If this is what others are seeing then I can understand their complaints. The underlying problem I believe is that the mpeg-2 system and probably AVCHD, has no mechanism to half decode i.e. use less CPU and give a lower resolution frame. If this is what's bugging users then two choices seem to present themselves. Get a much faster system or turn the feature off.
Other systems do seem to create proxies that can gracefully degrade when being decoded. I doubt too many of us would want Vegas forcing us to go down that path like they seem to do. On the other hand maybe we can have such as system as an option.
So my view is this new feature in V9 is a plus, it works very well when it works. It would seem like it can turn ugly when pushed beyond its limits and maybe there's some scope for further fine tuning. Overall so far I see it as a big step forward, if nothing else it's an acknowledgement of the users complaints.

[edit] One other thing I seem to have noticed. With adaptive preview on the size of the preview window seems to make quite an impact. If you're really having issues, try making it bigger or smaller. There does seem to be some sweetspots. Whatever you do don't just throw it out the window in the first minute. Play around with it a bit.
