For maximum Adobe Premiere Pro CS5 performance on Mac Pro desktop computers having the NVIDIA EVGA GeForce GTX285 graphics card, be sure to download the correct driver (cudadriver_3.0.14_macos.dmg).
This hint was provided in a Cinema5D.com forum post by “Grendel”, in response to which “bzshutter” wrote:
Wow, that driver solved the problem! Thanks so much ! I would have probably never found that driver.
Nvidia should really link to that driver instead of the older 2.2 driver when someone go to download the OSX driver for the 285 GTX.I’m stoked! Now with GPU turned on the CPU usage dropped at least by half. Rendering time is now 5 X faster! This was with three 5D mk 2 clips dropped
right onto the time line, with a couple of simple effects applied. A 15-second clip took 58 secs to export using CPU only, and 11 secs using GPU . Unbelievable!
I never thought this would be possible without some very expensive dedicated editing solution. Adobe got this one right!
“kenn.michael”, in an Adobe.com forum post, managed to get Premiere Pro to work with CUDA GPU acceleration on a 2008 8-core Mac Pro with 16GB RAM running Mac OS X 10.6.3 Snow Leopard. He concludes:
Re-installing the drivers did the trick! Make sure you have the 3.0.14 drivers, not the 2.3.1a drivers.
CUDA and Mercury Playback Engine are incredible!
