Bill I’m not sure why your mercury gpu accel is grayed out
other than your running lion. you might try the previous version of CUDA.
Tom D had an issue with the latest CUDA and he’s basically running the same as you.
I have an 8-core macpro, quadro 4000 and snow leopard.
gpu accel is on and working with CS 6.
I just now played a completely unrendered sequence from a fw 800
external drive. it was 1080p 23.976 and it plays smoothly all the way
through, though the audio sync drifts. But the exported video was
completely in sync.
In cs 5.5 it would have been stopping every few seconds and stuttering on playback.
