OT- slow audio waveform redraw connected to slow video card?

im having some super laggy audio waveform redraw issues

g5 2.5ghz quad
4.5 gigs of ram
geforce 6600 video card 256mb
working off various fw 800 and esata raids
fcp v6

seems to me that a 512 mb video card might make a big diff?
has anyone else out there done a similar upgrade and noticed big perf jumps?

Could it perhaps be the drive you have audio waveform cache going to?

i wouldnt think so. they are going at various times to fw800 or esata raids...

I've run across this too and have found it did make a difference where I had my waveforms cached. If I cached to my high performance raids they actually slowed down considerably. If I cached them to my system disk everything seemed much better.

These are small files that constantly get redrawn depending on changes. The other thing to keep in mind is that if the system bogs down redrawing waveforms, delete the waveform cache and start fresh. Of coarse that depends on how complicated and the number of audio channels, but generally it doesn't long to re-create and performance usually improves immediately.

i just did the anual zeroing of my boot drive and reinstalled all my apps - including fcp. no diff
