I woke to find four updates to CS6 (Au, Ae, Ps, and Pr) yesterday, which the Updater called "Dynamic Link Media Server CS6 1.0.1 Update."
I updated, and I updated my CUDA about the same time.
Pr started working slower. So, I reverted back, using my clone.
Not sure if this was a coincicence, or which update to blame.
I'm back to the performance from both that I was used to.
The CUDA update was for bugs I wasn't experiencing and for compatibility to 10.8, which I'm not running.
Was I too hasty? Do these Dynamic Link updates do anything? Improve anything?
MacPro3,1 - CS6 - Quadro 4000 - 10.7.4
Nobody has an answer?
Here's what one of the software engineers said when pointed to this thread:
"It would only affect video in Photoshop, video in Audition (non QuickTime), and video in Bridge.
His CUDA update most likely caused his problems."
I don't doubt your engineer for a second. I'm convinced now that the nVidia or most likely the CUDA driver is behind all my Serious Errors. I was getting them right after opening a project and trying to do anything at all today. I turned CUDA off, and was able to finish the project. When that was out the door, I reinstalled the CUDA and nVidia drivers, rebooted, opened my project, enabled CUDA, and Pr has been working without the errors.
Thank you, Todd!
