Fast Bounce - Good or not?

I have read/seen videos saying using Fast Bounce when bouncing to tracks is a bad thing and others saying it doesn't change the sound/quality. The Sonar Help Files say it does not degrade the audio. I'm curious about what everybody thinks about this? Any input? Personally, I have always used Fast Bounce and never really thought about it before. Am I missing out on something here?

Hi. I use fast bounce as well, unless I'm using an external insert of some kind. Then real time bounce is the only option. 
I haven't done any tests to see if there is any difference, but I can't hear any.
I use it because it saves me time. Simple as that 
All the best.

Same here, Zargg. However, now I have reservations about it. I guess I'll have to try it both ways and see if there is a difference. I was hoping others might have already done this and could save me the time.

I'm with Ken.
 
The only time I've ever done a real time bounce is when using External equipment.
 
Many soft synth manufacturers actually recommend using Fast Bounce

Its very simple really. Most plugins do not care about the rate at which audio buffers are sent to them to process. i.e. there is no difference in the processing if they process buffers clocked to the audio device as opposed to sending buffers as fast as the plugin can process them. In the latter case were making the most use of the CPU and it automatically throttles to how fast the CPU can process the plugin. Dropouts do not apply in this case so there is no risk of data loss.
 
The only exception may be certain plugins that rely on external hardware for their DSP or simply plugins that have bugs that get exposed in bast bounce. A long time ago some disk streaming plugins had problems in fast bounce mode but I haven't heard of any of those issues in a long time.

The only time I recall fast bounce being problematic for an in-the-box plugin, was with the very first release of Play 5. That was a Play5 issue and was quickly fixed by EWQL.

I reported a bug (problem reports, problem report email, and defunct problem reporter web page) wherein Sonar creates popping noises with real-time bounce (load balancing enabled) but not in fast bounce (or load balancing disabled).

I've always fast bounced...once I was having trouble with my computer getting overloaded with plugins/processing so I tried real time thinking it would be safer.  Turned out to be the opposite and the above issue is probably why.

Fast bounce and real time produce identical results, even with a large UAD setup (which someone above alluded to regarding additional dsp hardware).  Unless you're moving out into the analog domain using external inserts, anyway you count it.... its all just 1's and 0's

I think the quality is great *but* 1-with Melodyne Fast-Bounce to tracks can make it get out of sync (if you bought Melodyne as a plug in) and 2-agree that fast bounce will not work with external synths, of course.

Years ago, I had some issues with fast bouncing mixes that have BFD3 drum VSTi. Kit pieces would go missing in the fast bounce, but they wouldn't go missing in the real time bounce . . . so, for that reason I've always had the habit of using real time bounce, since I use BFD3 in most projects. No, I have not tested recently to see if this issue still exists, because I have the time . . . and real time bouncing is my "ear break"

In BFD2 there was a setting on the main page which had to clicked/enabled when bouncing inside a host such as SONAR.
I think it was labelled "Offline" and it turned red when enabled.
 
Without this, notes were dropped randomly on export/bounce.
 
Don't know if there's a similar setting in BFD3 but might be worth checking.

Thanks B_Jonesey . . . for reminding me about the "Offline" feature in BFD3. Though, when I checked the manual
I think they're saying to only turn it on when actually rendering a fast bounce, it should not be left on during normal playback:
 
"Offline mode
This switch is intended for use with hosts that provide an offline (non-realtime) bounce or mixdown facility. When the Offline switch is activated, BFD3 waits for all data to be properly delivered from the hard disk before allowing the host to continue, ensuring that sounds are not cut off before their full decay is complete.
Please note that Offline mode is non-realtime, and should only be used during offline mixdown or rendering in your sequencer, if it even offers this feature. Do not leave the Offline switch enabled during regular realtime playback. If your sequencer only provides realtime bouncing facilities, you should leave Offline mode turned off at all times."

I have had a similar issue with Battery3. It's not always immediately obvious either. So to avoid such problems I tend to steer clear of using Fast Bounce.

I've never used anything but fast bounce and today, with new aux tracks and ability to render the VST instruments into a track easily, why wait for real time ALTHOUGH.... sometimes fast bounce is actually much slower, especially if you have audiosnap enabled and not bounced.  However, things can effect real time bounces like audio glitches in the room or whatever you may hear thats not actually opn the track.  Fast bounce removes any chance of that.   I alway print all my external work anyway to avoid having to recall the settings on HW in the future so fast bounce to me is the most reliable method and absolutely the same everytime
