unique_screenname_here Oct 12, 2011 1:23 PM (in response to designII)Is "Enable OpenGL Drawing" also disabled in Photoshop's preferences? Have you installed the latest NVIDIA-provided graphics drivers for your graphics card?

designII Oct 12, 2011 1:29 PM (in response to unique_screenname_here)Hi unique, thx for your response. "Enable open GL" is checked in CS5 preferences. I am limited to only two drivers for my card. I use Autodesk's Alias Surface Studio, and stick to the recommended drivers.

unique_screenname_here Oct 12, 2011 4:29 PM (in response to designII)Okay, the drivers may pose a problem although I suspect they are probably not the cause of this problem as the Photoshop preference is not grayed out. What is the mode (colorspace and bit-depth) of the images you are trying to process?

anthonym_1 Oct 20, 2011 12:22 AM (in response to designII)I strongly believe your problem is not the video card or the drivers for that card, but Windows XP Professional. I had many problems getting Windows XP Professional (64bit) to
work with my Nvidia card and drivers when trying to get CS5's flick panning and rotate screen functions to work, which rely on Open GL. After several weeks of patches and
work-arounds and despising the idea of upgrading my OS, I finally gave up and just updated my OS to Windows 7. I thank myself to this day.

designII Oct 20, 2011 5:11 AM (in response to anthonym_1)Thanks for all of your answers. I believe I had downloaded the 5.1 version but I am running 5.0. I am upgrading to a new computer today with better video, more ram, and win7. I will try again after they swap machines.

unique_screenname_here Oct 20, 2011 1:48 PM (in response to designII)Yeah, WinXP is a bit of a headache as anthonym_1 noted. My advice would be to install the 64-bit version of Win7 while you're making the change. Make sure to put a decent graphics card in your machine while you're at it--you don't need to go overboard but a DX11-capable card with a good amount of video memory (I look for at least 1GB these days) and plenty of shader cores should do the trick.
