Sudden and Sever Latency Issue

Working on a project that has already had many tracks of vocals recorded. Came in today to put the last couple of tracks on, and the delay between the actual voice and the voice coming out of the headphones was huge. I had to pull the fader down and take the headphone off one ear to record. All that has changed in this track is that I have frozen or bounced some instruments so I am working with all audio tracks. This should be less CPU load, not more. Any ideas? This is not going to work. Thanks.

If something like this happens to me, I can usually trace it to a convolution reverb.  Have you recently added Perfect Space or similar?
 
If so, disabling it does the trick.  I believe some other effects that use "look ahead" can do this.
 
Just a thought, sorry if it's no use.
 
Hope you get it sorted.

Konradh - I hope it works.
 
I struggled with this for ages when trying to track guitars through GP5 and Amplitube3.  I knew my PC was powerful enough, and the CPU always looked barely used.  I had started to think it was a problem with the Windows7 drivers for my interface.  Killing Perfect Space stopped the latency issue in its tracks...
 
Now, I tend to use something like Pantheon LE if I need reverb on during tracking, and replace it later with Perfect Space or Reverberate.  Or i just turn them off whilst recording.  I guess you could freeze them instead, I'll try later.
 
Let me know how you get on.

Did you sort this out?
