Choppy picture .. is it ATI

[Marcus Vasques Osorio]

I have a Mac Pro 8 core 2.8Ghz, 6GB memory, ATI 2600HD card (standard)...
QT 7.4.5

The computer is only one week old

I am using it for verifying and backing up RED material on-set but both the QT refrence files and REDCINE are choppy?

REDCINE plays back fine until movement then it gets hacky, not even the QT Medium files can be played back in Real-time??

Any suggestions why

Do you have a dedicated media drive and are files on it ?

I get around 15 ish fps in Red Cine playing off an internal Raid stripe with r3d files.
Can only think thta you have your files on the boot drive.

quad 2.66, 5 gig, ATI 1900

Maybe 6gb is a strange # try 8.

lol - vff

The media files are both on a e-sata raid (g-tech) and internal harddrive... so the drive speed should not be a problem.... Do you think that I should upgrade my graphics card?

Yes!!!

Quadro 5600 from what I have gathered is the way to go please correct me if I err ...

I took out the stock RAM when I upgraded to 8gb (taking out the stock 2), and that sped things considerably up.

Noone else seems to agree, but barefeats...

I have not tried to re-insert the stock RAM after recent systemupdates.

For anything but games and 3d renders, the ATIs seem tom be the fastest under osx due to driver issues in OSX
