The usable cards are discussed in:

The NVIDIA GeForce 7300 GT is mentioned as being problematical:
"Note: Due to technical issues we enable OpenGL for the 7300GT, but we had to disable Advanced Drawing and 3D Acceleration."
and the ATI X1900 XT while listed as being usable on a Windows machine, is not included in the list of crds that are compatible with Open GL and CS4 on a Mac.
I have a NVIDIA GeForce 7300 GT and the enable the OpenGL Drawing check-box does show. However, Advanced Settings/Advanced Drawing is grayed out.
From the info. in Adobe’s TechNote it would appear that even installing the optional "AllowOldGPUS.plugin" won’t make OpenGL Drawing available with the GeForce 7300 GT unless Apple updates their video drivers which are part of OSX.

Which is why I opted for an 8800GT card. Apple may never update drivers since they no longer sell the card.
"The ATI X1900 XT is listed as being usable on a Windows machine as well as on the Mac. Do you have the ATI X1900 XT in the first Slot? "
Yes, it is in the first slot…
to Welles:
Thank you for that screenshot. Maybe it is worth to deinstall the GeForce for a try-out…
I posted this problem at the Apple forum too, to see if there are others having the same issue.

I’m guessing that Photoshop is confused with multiple video cards.
I had two identical 7300 cards in my MacPro. When I installed PSCS4 the card was seen and GL was turned on (but not Advanced Drawing). I upgraded 1 card to an nVidia 8800. Now sporting one 8800 and one 7300. GL was not available, but should have been. Here is where I’m guessing that PS saw two video cards that were different so it decided GL wasn’t an option.
I then installed the AllowOldGPUs plug in and the 8800 was seen and GL is available with Advanced Drawing as well.
Try removing the 7300 card if you are not driving 3 displays.
Also, are you sure you want to stay with 10.5.4?
If it is not working, then something in the driver is failing, or telling Photoshop that it does not have the capabilities. And right now we don’t have any good way of determining exactly which part is failing or reporting capabilities incorrectly.
Scott – yes, the GL driver may not be happy with different card models.
I deinstalled the GeForce card and now i can enable every option regarding OpenGL in PS CS4. And i also updated to 10.5.5 (of course after writing a backup first).
So there is "an issue" with the GeForce card or two different cards under PS CS4.
But i can not see any acceleration in PS. When opening an equirectangular image (6000×3000 px) and convert it into a spherical panorama PS is painfully slow when repainting the image.
Not really being worth any change in the system for now…
Thanks for these hints – Peter
I"m having the same problem. I have 3 video cards, one is the x1900. And same ‘dialogue’ in the Preferences pane of Photoshop.
But.. sounds like… it’s not worth the effort of tracking it down or making major system changes, so, I’ll leave well enough alone.
The issue is not card specific. The problem is that the Apple OS does not function well with non-matching, multiple video cards. It doesn’t matter which cards you have, if they aren’t the exact same cards, there is the problem. You can install 3 ATI x1900 cards and it will all work great, but mix cards and the OS has issues.
I have the same problem. I also have a X1900 and a BlackMagic card.
BUT, why is it that open GL works fine in AE CS4 (and in my 3d apps) but doesn’t function at all in CS4 bridge and photoshop? Seems like adobe isn’t on the ball between app dev departments.
Or something.
I do not see why the BlackMagic Intensity Pro would be an issue as it is a capture card and not a display card per se?
I own an intensity pro card and wil instal it to see if it disables the open GL on my Nvidia GeForce 8800 GT card.
This is not quite right.
Ok so i just installed Blackmagic’s Intensity Pro and the newest drivers from the website.
Just what I thought it has no effect on the Open GL support and as my memory serves me it is your card Radeon X1900 which does not ether support Open GL 2.0 or Shader 3.0. The card has to support both as I understand it.
To my memory which is sometimes not the best and sometimes amazing, I recall the Radeon X 1900 is not supported for PS CS4 I do not know about the Bridge.
I also have a X1900 and a BlackMagic card.
Having two dissimilar cards installed seems to cause problems with OpenGL on a Mac.
Try removing one or the other and see what effect that has on OpenGL.
PShock you are correct I must have been an older model Radeon card I was thinking of but clearly you are correct.
The Blackmagic Intensity and Intensity Pro is not a graphic or display car it is a dedicated Video in and Video out card for capturing HDV and also analog to HDV as well as displaying on a Video Monitor as you capture and edit.
It will not be listed under Display and Graphics in the system profile but rather in the PC slot area.
It has no effect on the Open GL mechanism.
I have it installed as I wrote along side of my Nvidia 880 and it work fine with open GL in PS 4 nothing different what so ever.
Although the poster does not state what kind of Blackmagic card?
Even so I do not see how it could possibly interfere.
My BM card is a DeckLink HD card. I don’t have the time to pull it to see if that’s the prob. But, I can’t see any other reason open GL works in all other apps except PS CS4 and bridge. Your right about the fact it’s not a "video card" per se, just groping for some answers. Obviously, not a real solid implementation.
