You will have to ask NVidia. The card/driver don’t support something that Photoshop requires for GPU acceleration. That might be something fixed in the driver (which I hope you have already updated).
I just installed the Master Collection. I have that same driver with a GeForce 8600GT/256Mb RAM, it works here just fine. Know that doesn’t solve your problem though.
Thanks folks for your reply!
I have installed the latest version (178.24 WQHL) of GeForce drive, but CS4 doesn’t work with GPU acceleartion. I am very confused by that.
I would imagine that in time the drivers will catch up. I’ve been wondering if PS CS4 would run very well on my notebook even with the GPU enhancement. It’s new and fast with 4GB ram, but CS3 wasn’t spectacular, but it ran well.
I’d contact Nvidia tech support. If they get enough calls it may impress them enuf to look into it. Maybe they already are and would have some info.
Have you checked the compatibility sheet to see if your card is on there? I don’t have the link handy, but it’s around here somewhere.
I wonder if there’s any difference regarding the GPU running PSCS4 x64 as opposed to the 32-bit version?
I had actually used "OpenGL Extensions Viewer 3.0" to make a test.

Windows Vista Home Premium 32-bit
GeForce 9500 M GS (512 RAM)
4 GB RAM
My GeForce card is drived by 178.24 WQHL version.
CS4 just don’t recognize the video card, and GPU function remains dimmed.
I can play 3D games, but CS4 GPU just does not work anyway.
I would imagine that in time the drivers will catch up
I would imagine that CS4 was tested with existing drivers, so maybe something else is the problem.

I have a 7950GT with 178.24 WQHL installed on XP Pro SP3 32bit and CS4 works with GPU enabled although the 7950GT card is not on the Adobe tested card list. Probably not much help but it shows cards which are not on the list do work.
Maybe a sticky thread could be started where users can post a list of setups which do work it may help those still thinking about upgrading.
I had a similar problem. Sometimes CS4 tried to disable Open GL even when it wasn’t on. I also noticed that there was banding in gradients. In the end I uninstalled the driver and reinstalled it ensuring that antivirus, Spybot etc were all off. Problem seems to have fixed. I think it is just a very buggy driver
Robert, thanks much, your info is helping.
Something should be wrong with my operation system perhaps. I re-installed the entire system today due to a sudden unexpected virus attack, and I used 175 version of GeForce drive instead of 178.24, I closed my anti-virus software prior to the installation of video card drive, then it worked. I am not sure if that is the factor, but now my CS4 works for me with GPU acceleration.
I am glad with the result and quite appreciate all suggestions by everybody. Thank you all.
I had a problem with my Nvidia 8800GT, 512MB, graphics card with the Nvidia driver, v.178.24, that I updated to a couple of weeks ago, prior to the installation of Photoshop CS4. Three days ago I received my Photoshop CS4 software and I installed it. Every time I opened Photoshop CS4 a message popped on my screen, Photoshop has encountered a problem with the display driver, and has temporarily disabled GPU enhancements. Check the video card manufacturers website for the latest software.
Every time I went into Preferences and set my GPU Setting to Enable OpenGL the next time I opened Photoshop I would again get the popup message.
Since my graphics card was included in the list that Adobe had tested, I wondered if a prior driver version was tested by Adobe instead of the newest version. With this thought in mind, I rolled back to my prior driver, 178.13, and Photoshop seemed to be OK with this older driver version.
Now that the older driver, v.176.13, was operating OK, I decided to update to the newest driver, v178.24, now that Photoshop CS4 was installed and had no apparent problem with older driver. After the download and installation of the newest driver, v.178.24, with Photoshop CS4 already been installed, Photoshop seems to be compatible with the newest Nvidia driver and the popup message no longer appears. Now when Photoshop is opened, OpenGL Drawing is enabled and everything seems to work fine.
There might be a quirk in the installation sequence between Photoshop CS4 and the newest Nvidia driver versions. In any event, the installation sequence I described above seems to satisfy whatever it was before that irked Photoshop.
My OS is Windows XP Pro and Im running Photoshop in 32 bit mode.
I had problems to the effect that Open GL was selectable in preferences (performance), but it wouldn’t get operational.
I have a Nvidia 8400 GT, 512MB RAM. I had updated the driver to the newest prior to installing Ps CS4, without that resulting in an error message once CS4 was installed. CS3 is still on my system.
I opened the configuration for the graphics card, and selected the Photoshop preset that was there.
This enabled some (but not all) of the 3D properties of the card, of which most settings mean not a lot to me.
After relaunching Ps the Open GL functions now work. Also my card is mentioned in that preference dialog. Before all this the field was blank.
I have Win XP pro SP3 and all is off course 32bit.
