Don't understand how to enable OpenGL?

[Neil_J...@adobeforums.com]

I just installed Photoshop CS4 around a week ago and as many have already said it feels pretty sluggish compared to the CS2 that I upgraded from.

I get the message "photoshop has encountered a problem with the display driver, and has temporarily disabled GPU enhancements..." which essentially disables OpenGL and I am sure probably has some adverse effects.

I have a modern up to date computer so I don't see what the issue is. Whenever I try to enable it when I restart it tells me to either search for updated drivers or gives me the error. I hate thinking I paid all this money for something I am not getting optimal use out of.

Thanks for any help

Specs:
Windows XP SP3
Directx 9.0c
4GB Ram
Quad 9450 CPU
Nvidia 8800GT 512MB video card (which is on their supported list)
Most up to date video drivers you can get 178.24

What is your screen resolution and layout? It's possible that your graphics card is not correctly reporting the resources to your system with odd monitor combinations and NVidia Desktop settings....

I have a very basic 1600x1200 resolution which is pretty standard for a non wide screen setup.

I just deleted my CS4 settings file at startup as described by adobe's help files as they said it might be holding onto old info. I don't get the initial error now and I am getting some changes (no more flickering when moving the files around, and there are smooth transitions now between zooming and moving) so I am assuming this is the OpenGL feature set?

I still do get a popup on load however that says "to download your latest video drivers please visit..."

I wish adobe provided a utility that tests your functionality (much like direct x and some video games do) and would issue a pass or fail and if so give an explanation.

The issue is as the alert says: your video card driver has returned an error when it shouldn't have, and Photoshop has to turn off the GPU support because your video card driver is not working correctly.
