Vegas 3.0c - Tracks won't sync after format

I've been using Vegas 3.0c for well over 2 years and have recorded countless albums with it.

A local band made their way down to the studio last night. We set up drums and we managed to get some great sounds on the drums.

We met back this morning and started tracking. I noticed that the recorded tracks were not in sync on all the tracks and that the problem got worse as the song went on. Longer songs became more and more out of sync.

I first thought it was my converters (Mytek AD96s) not syncing up with my soundcards converters ( 2 Delta 1010 soundcards) was the problem as this can be an issue, but I ruled that out for a number of reasons.

I noticed that while recording my CPU % was maxed at 100% the entire time. While I was doing 13 tracks of 24 bit, 44.1khz .wav audio, I don't know why it would have a hard time. What is even more interesting, is the fact that on playback it only uses about 33% and that includes the additional demand of effects like eq and reverb (mostly Waves stuff).

Something has got to be inefficiently using resources during the recording stage.

I'm using the same software, Vegas 3.0c (the legal version), with a legal copy of XP with SP1 (this is a change from my hacked version in the past that worked great for 2 years). I'm using the XP 2000 CPU and 1 GB of RAM of DDR ram. The computer is dedicated to recording. It has one 20GB C: drive and (2) 200 GB ATA133 drives for audio. I noticed that my meters that show the level of a given instrument were freezing up and going very slowly as if the computer was overloaded. I reduced the graphic accelerator to "fix serious problems" level and reduced the colors from 32 bit to 16 bit, but that didn't seam to help.

When I began recording last night I didn't have any any problems....but we were only doing 10 tracks for short bursts (30 seconds). When we added guitar, vocals, etc I got up to about 15 tracks and this is when I started having problems. Last night, my computer was not completely optimized. I did a few basic things like turn off the screensaver etc. After the computer started acting stupid and I didn't feel like the converters were the issue I went down a list of 30 optimizations for XP. That didn't seam to do a damn thing.

The computer seams to work fine when doing anything other than hitting the record button on a large number of tracks. This should not be CPU intensive, by my understanding. At the moment, I can not think of any way to further optimize my computer.


One thing I noticed that I may try next.
My Matrox G450 was automatically detected in Windows SP1, but had not been in the past. I have drivers that I had to install before that I did not use this time. I may try installing them. The drivers that I had to install did give me more options in control panels and this leads me to believe that they may be quite different than the drivers installed by SP1.


If you have any ideas off the top of your head, send them my way. I don't think the computer itself is bad. It seams just as fast as before when it comes to mixing. Is there a test that can tell me how fast my computer is running? Maybe I damaged my CPU and it is running slower than usual?...just a rough guess.

Is there a setting in Vegas that will allow me to reduce the load on the CPU or at least spread it out over time? I've never had this problem before and I am concerned.

It turns out that the reason for all my problems was caused by the IRQs getting weird.

I had a few problems when I had to recover older hard drive data. It was easier to install a net card into the computer when it came to troubleshooting.

The temporary installation of the PCI net card was enough to throw off the 2 Delta 1010 PCI cards to the point that doing anything mroe than 10 tracks was completely unusuable.
