Well.... Vista is installed and everything seems to run fine. Did the upgrade to keep all programs and settings intact. I needed to re-authorize a few apps like Reason and some of the Native Instruments stuff but that wasn't a problem at all.
I'm currently running Vista Business 32 bit - for those of you that are running Vista, here are my Index scores:
Processor Intel(R) Core(TM)2 Quad CPU @ 2.66GHz - 5.9
Memory (RAM) 2.00 GB - 4.7
Graphics NVIDIA GeForce 7950 GX2 (Microsoft Corporation - WDDM) - 5.9
Gaming graphics 783 MB Total available graphics memory - 5.8
Primary hard disk 503GB Free (695GB Total) - 5.7
(Computers with a base score of 5 were the highest performing computers available when Windows Vista was released)
I have not yet been able to fully test things out but so far I haven't had any problems running any audio apps.
I did receive a warning from the Vista install that Reason might have a few problems but so far I have not had a single one. Reason runs at least as well as it did under XP - possibly a slight bit better.
AcidPro runs great under Vista - no problems at all (yet)
Some VST's appear to be running faster - Samplers and Romplers seem to work a little quicker. I'm not sure if it's due to the USB ReadyBoost feature or better disk access in general though.
I have not yet looked at anything related to WaveRT but overall it seems that I do have lower latency across most audio apps that I've played with so far - at least with standard ASIO drivers. I'm not certain but I think that untill apps support WaveRT it will sit dormant. Either way, if the developers release patches or updates or whatever it is they do, then I'll look into it more. For now I'll wait on any changes in this area.
I've read that some apps will have problems but there seems to be decent compatibility options in Vista for programs that don't work directly out of their boxes.
Here's by bottom line -
So far I think that audio apps should not be a major consideration when thinking about an upgrade to Vista.
Everything seems alright so far. Then again, I'm running a pretty high end system - PC's with middle or lower end specs may not do nearly as well...
If you're upgrading anyway, like I was, then it seems that audio apps are working at least as well as they did in XP - possibly a little better (but only a hair).
However, I have yet to see any major audio advantages with Vista, so if you're running XP and happy with it then you probably wouldn't want to upgrade just for audio's sake.
I hope that helps someone out there -
