10.6.4 graphics issues

post #1 of 5
Thread Starter 
Hello

I have spent several hours the last few days trying to understand the issues that I've been dealing with since upgrading to 10.6.4 (and coincidentally Adobe CS5).

Since upgrading to 10.6 a few weeks ago (and immediately updating to 10.6.4), when I received my new copy of CS5, I have been experiencing spontaneous crashes -screen flickering (dual monitor), where I could move the mouse around but no UI responsiveness whatsoever. Only a hard reboot (hold down power button) would resolve it.

Now, this only happened to me a half dozen times in the last few weeks, and always while using Cinema4D, so I didn't think this was related to OS at all - initially.

In the last few days I've come across the following forum topics on both Apple and Adobe discussion boards:

http://discussions.apple.com/thread....67019&tstart=0

here is a youtube video illustrating the flickering:

It has confirmed in my mind that there is a serious flaw with the graphics drivers in 10.6.4, but so far it does not seem to have been acknowledged (at least directly) by Apple.

The only suggestion (from Adobe forum) is to "down-grade" to 10.6.3

I should note that this is happening on a 8-core 3.2Ghz Mac Pro (2008) w/ NVidia GeForce 8800GT, 16GB RAM

It does, in fact, seem to disproportionally (if not exclusively) affect machines w/ NVidia cards.

If this is already being discussed somewhere on this forum, please let me know, as I was unable to find a thread.

I'd like to hear form anyone who has any further insight on this topic, or from other who are experiencing the same thing.

They do have a Snow Leopard Graphics Update in beta right now.

As far as I can discern, Apple's GPU drivers/OpenGL have gotten significantly worse with each 10.6.x release.

It reminds me of Jobs, re: AT&T networks. "Things tend to get worse right before they get better. If you believe that, things should be getting a LOT better, soon."

I sincerely hope that Snow Leopard's optimizations included OpenGL and graphics drivers, but they weren't ready for prime time.

Then again... the iPad and iPhone seem to be their focus now. iPods/iTV are next. I think we might be holding our breath for a very very long time.
