Ever since I have upgraded to 7.3.1 from 6.9.2 on my Imac G5 it seems like everything is slower. why is this? I try to start a NEW session with no plug ins and just do a vocal test, start recording and it has about a minute delay and then goes? And on play back it takes forever as well. Is there a way i can speed us this process. It also says that my buffer needs to come up, and when i have it too the max it still says that? Could it be the RAM of my computer. Should i upgrade to a dual G5?
