He's been trying to tell you. If you generated a realdrum track, it used the same clock as midi and metronome.
And no, I was not talking about MIDI drums. I was taking about realdrums, like you asked about.

The realdrum generator uses the tempo in the tempo clock to generate the drums, and it's the same exact clock that midi uses. It will stay in sync, unless you have changed the tempo in the tempo window...

If so, just double click the ACW window and you can re-write the tempo map from there, just tell ACW to redo the bars when it asks (pay attention, it comes up right away). If it doesn't do it automagically correct, you then hit play inside the ACW and tap the F8 key on the first beat of every measure to manually do it.

I like iusing the method I mentioned over using the metronome, because I seem to be able to push the volume more when it's an audio track (before getting distortion), and then I don't having the processor running a synth to hear the click. I could just pull the click sound from an external source I suppose, and save an audio track...

I do not work here, but the benefits are still awesome
