Audio Performance Meter in DP goes red with BFD3 on


I have a longtime project in Digital Performer 11.22 that, all of sudden, the Audio Performance meter pegs to the red making it unusable. I’ve tried increasing the buffer in DP to no avail. I have midi tracks for the drums. If I mute BFD there appears to be no problem. So far, it appears that my problem is with BFD3. I’ve had for years but now it’s a problem. Any suggestions?

For testing, I opened up an older project with BFD3 and the same thing happened. Once I started playing the project the Audio Performance meter pegged.
