I am having very similar problems with my G5 Quad 2.5 Power PC & Pro-Tools 8 LE. Lots of errors saying delete some plug-ins (while running very few) or raise the hardware buffer size which I am running at full capacity (1024). My cpu meter on the G5 shows a 15 to 20 percent higher rate than the cpu monitor in pro-tools and goes into the red. Any solutions? 7 ran smoothly with Tiger 10.4. Any help or input on this matter is greatly appreciated.
