I used to run a digi 002, pt le 6.9 on a G5 dual 2.0 and sometimes had to run at 2048 hardware buffer to keep it running smooth during a mix.. never had severe latency problems. But....

current system
HD1 accel pcie, PT 7.3.1
mac pro 2.66 w/ 3 GB ram
lynx aurora 16 (love it!), NO digi 192/96 needed of course
running both TDM and RTAS

THE ISSUE
Any time I use an aux channel (say I'm affecting both OH channels the same) to put plugins on, I get severe slapback-ish lag on the aux. I mean you can watch the meters move obviously behind their source track's meters. The only way to reduce it is LOWERING the hardware buffer (in playback engine dialog) to 512 or even 256 sometimes. I find myself mixing at 256 then upping it to 512 to get through a bounce. I thought the hardware buffer worked the other way around???

The auto delay compensation (ADC) has NO obvious effect on it, regardless of it's setting.

Somebody shine some light on this oddity.

PS. it's been doing this ever since I bought the HD1.
