Note: I'm interpreting the OP as saying the relative volumes within a track are different depending on whether the track is rendered to a WAV or played from BIAB. That is, the dB difference between certain loud and soft sections differs. If it's the overall volume of a track being discussed, then what I'm going to post doesn't apply:

I did a quick test using the TEXSWGP RT style and generated a short 22 sec song. I rendered each individual RT track (drums, acoustic guitar, pedal steel) to separate WAV files. I then recorded from the audio output of my laptop each individual instrument soloed by BIAB into a Zoom H2 recorder. Imported the Zoom files to my laptop and used Sound Forge to normalize each file (rendered and Zoom) to the same peak dB value. All 3 instruments have the same (within a few tenths of a dB) RMS (average volume) level for both files. The waveforms also look the same.

Maybe what the OP (and others) are saying depends on the RTs involved, but I see no difference.

I'm using BIAB 2010 Build 297.
