I was assured that OpenGL was installed correctly on my Mac but it doesn't work in PS. I was told it must be an Adobe issue. In preferences the OPENGL drawing is grayed out. I've ran Adobe updates and restarted my Mac and still get errors "only works with OpenGL documents".

Details of your video card are needed.
#2
You need one whose driver supports OpenGL2 and Shader Model 3, with 256 MB of V-RAM on board.
#3
Actually, only 128 MB VRAM on board to get some OpenGL features. Some 3D GPU features in Ps Extended will require 256 MB in order to use.
Leona, video cards specs are needed to trouble shoot this, but even with a supported configuration, you may get that message in some conditions (ie. multiple windows open, high screen resolution on multiple 30" monitors). However, in your case with the preference option being grayed out, this sounds like you either need to check your video card driver or the video card itself is underpowered.

Steve,

Just curious: Could one drive two monitors off one single card with only 128 MB VRAM? The thought of running Photoshop with a single monitor often escapes my mind.

Yes.
I did this with the 6600LE that came stock with the G5

And you had OpenGL in CS4 with that card?

I am running 2 monitors if that makes a difference.

No you just asked if one could run 2 monitors with 128MB RAM.
actually OpenGL worked with the AllowOld GPS.plugin

My question was not without context, Buko. It was addressed to Steve Guilhamet of Adobe and it referenced his post.
Obviously I was only wondering if a card with just 128 MB of VRAM is enough to drive two monitors with OpenGL functions fully enabled.
If you had to use the AllowOldFarts plug-in, I bet the Advanced options were not enabled.

I don't remember now.

Hi Ramón,
I haven't tried to drive 2 monitors with a 128MB card. I'm guessing that the particular OS, card and driver, along with image size, and monitor resolution all contribute to the overall experience. I wouldn't be surprised if it didn't work.
My mention of 128 MB VRAM was meant to reflect minimum requirements for enabling OpenGL drawing. The MacBook Air (GMA x3100, 128MB) gets OpenGL drawing, but is also a single small screen at 1280 x 800.

Hi Leona,
I haven't tracked down an early 24" iMac. You might try disconnecting the secondary Cinema display, or dropping the resolution on your primary to see if that changes anything.

Steve,
Thank you for the courtesy of your reply. I was just being curious. :)
