I've been trying to stream PCM data to each of the 8 channels on the Sega CD, and while it works for the most part, my issue is that it's been causing lag. What I mean by that is that it's been slowing down my driver by quite a bit and I am unsure what the cause is. Is the PCM chip really just that slow or could there be a problem? This is what I have. I guess it will help to say that I am using INT3 and have the timer set to 1. Could that be causing anything?
