CS4: no image in main window when using openGL

[Dominique_...@adobeforums.com]

I am using Photoshop CS4 on a 32bit vista Q6600. When I installed CS4, I had a graphics card based on a 8600GS. Photoshop run fine, even in openGL.

Not I upgraded the graphics card to a 9600GT for better performance. CS4 still starts, but when a photo is loaded, the photo appears correctly in the navigator, but the main window where the photo usually appeared remains grey, as the background. When moving around this window, the photo appear, but as soon as I release the mouse button, the window turn grey again...

When I deactivate openGL in CS4, everything seems to work.

I am having the latest NVidia drivers installed 178.24 (with both graphics cards).

I tried to reinstall the driver, no change.

Anyway of getting CS4 work in openGL with this 9600GT?

I probably found the problem. The new graphics card from ASUS installed GamerOSD and ASUSSmartDoctor. I deinstalled these and now openGL is working again in CS4. I guess these ASUS tools do install some additional DLLs...

This whole mess may in large part be due to software conflicts. People have stuff on their computers that NVidia, ATI and Adobe do not have on their test systems.

You are right.

As the old graphics card based on 8600GS used the same driver as the 9600GT I started to have a closer look and found the only difference, the additional ASUS tools. Once uninstalled, using just plain nvidia drivers, CS4 worked as expected.

I've been suspecting suites of card utilities all along as a source of trouble. I wasn't joking when I said uninstall everything and try the generic driver.

I remember trouble years ago with ATI Catalyst.
