Yes, the UAD-1 plugins have an inherent delay which is twice your project latency. This is because digital information has to travel out to the DSP card and then back to your audio host app. IOW, if your project latency is 5.8msec (for Vegas you set this from the Audio options, in Preferences) the delay will be 11.6msec. But, most modern audio host apps these days, including Vegas, have full auto PDC (Plugin Delay Compensation), which re-syncs all of your tracks automatically when you are mixing. So this is not a problem. You do need to use good low latency audio drivers (like ASIO), for best performance. I recently found that a 2.9msec (128 sample buffer) seems to work best, in Vegas 6, using the VST versions. I have had mixed results, in previous Vegas versions and would recommend only using Vegas 6 with it's native VST support , at this point. I would avoid using the DX versions. These are my personal observations, and of course, YMMV.

thanks

how do i tell if im using vst or dx...i just installed the card

If you're using V5 or older you can only use DX plugins.
If you're up to V6, then you can use both and the VST versions have a little "vst" next to the plugin icon in the fx manager.

cool thanks

any tips on improving performance? The UAD mater says Im only at 29% CPU and at certian parts of my song Im still getting the cracles that happen when the computer is choking. I know it wont render that way but it seems like Im dogging out more than I have in the past.

plus it doesnt make scense that the card is supposed to be taking the load and I bog down if I add a reverb....i swapped out a bunch of Waves stuff and am not running too many plugs...I dont get it.

I guess I'll let you decide, heres what I have running:

Main L3
Drum 117SE
Cymbals RenComp
Bass 117SE
Rhythm Gut EX-1
Lead Gut EX-1

Voice Over
RenDeEsser, RenComp, RenEQ, RealVerb

3 InsertBuses
1 SuperTap
2 RealVerb
3 EX-1

What %s are both your native CPU and your UAD-1 CPU running at?

Also open your system information and tell me if there are any IRQs being shared between the UAD-1 and other devices (like a sound card or network card).

UAD CARD shares IRQ 17 with
NEC PCI USB Open Host Controller

NEC PCI USB Open Host Controller also occupies 3 other IRQs making it seem hard if not impossible to get the UAD on its own...any tips would help

Have you tried putting the card in another PCI slot?
The UAD really needs it's own interrupt.

Sounds like it's time to play PCI slot swap.
Because the UAD-1 card's nature, it can be unhappy when sharing an IRQ.
Try moving the UAD-1 to the #1 PCI slot (closest to the video card) and move the other cards to other slots and then check IRQs.
