I just installed GPO and I´m quite pleased with the sound of it. But I get drop outs very often. So I wanted to ask, if I did everything to get most out of my programs. I have:

G5 DP 2x2,7 RAM 4,5GIG, 10.3.9.
Sib 4.1 Kontakt 6.3

RAM seams to be sufficent. So I turned DFD off. I turned reverb off. I turned animated keyboard in Kontakt off. Is there anything I forgott to make the performance better?
