An Upgrade to Latency (Really)

[Genie]

Hello, i've been using cwpa9 for two years under NT4. I was happy as a fed dog. Then i upgraded to Sonar and win2000 and after a week and a half i'm ready to run away. I have serious latency issues. Here is my system.

PIII600
Intel Board
256 PC133
2 HD (5400 for OS and Software, 7200 for data)
SoundBlaster Platinum(for MIDI)
M-Audio Delta 44 for Audio
Win2000

I am using the 5.12.1.9 delta driver for win2000
Installed Service pack 2 for win2000
Installed Service pack for sonar

I've played around with the latency slider enuff to make me puke. the latency doesn't become unnoticeable until the slider is pretty much all the way to the left and then when i play a midsized project it dies and i feel shame.
I've increased the i/o buffer up to 264.


Latency occurs when i monitor the playback on a channel on which i am recording.

Signal chain: Guitar into mackie into delta 1/2 in, output to 1/2 out into amp. When i arm a track and monitor the playback it seems to take about a half second to hear it. sounds like a long delay.

Any ideas, i'm half ready to dual boot nt4 and 2000 and record in nt4 and mix in 2000, this doesn't sound cool to me and i'm hoping to avoid it because double and triple booting microsoft os's will cause me to become a linux purist.

Thanks for listening.

It's possible although unlikely that the O/S switch brought on the latency problems, I had the same issue initially when upgrading PA9 to Sonar under Win98. I had 2 cards installed, a Soundblaster Live & Aardvark Pro DX6, and all I did was upgrade to Sonar and my latency settings went all to hell. It was definitely Sonar.

Questions... is your latency when recording instruments just visual, i.e. only the VU meter is delayed, or is the actual signal delayed too? I am not experiencing any signal delays, but the VU meter is about 1/2 second behind the signal. I've learned to live with that.

Also, what happens if you use the Soundblaster instead of your Delta card as the audio card in Sonar? Do you experience the same latency issues? Something to check in case it's related to your audio drivers...

Did you uninstall PA9 yet? If not are you experiencing the same latency there? What was weird for me was, I had PA9 setup and tweaked perfectly. Then I installed Sonar, and had it run a performance analysis and the numbers were WACKED, like WAY bad. Then I went back to PA9 and ran the performance analysis and IT started reporting wacked numbers too! I think Sonar installed something into the DirectX layer or something global that affected latency, because before Sonar everything was cool.
