OpenGL and Photoshop

So, I don’t know about you guys, but I was pretty excited when the photoshop tutorial used something as simple as a change in view to measure and execute a precise and neat looking crop that greatly improved the picture.  I was planning on using it myself, but photoshop gave me an error: the rotate view tool only works with an opengl enabled windows document.

I had no idea what this meant.

I’ll give you the short of it, though here’s a link to what I found:

Essentially, OpenGL allows certain programs to interface with one another.  In the case of photoshop, OpenGL uses the GPU of your graphics card to enable and enhance certain photoshop features, like the rotate view tool, prettier animations, and smoother zooms.

Although OpenGL automatically comes installed with all Windows and Mac operating systems, your OpenGL capability is limited by your hardware and updates.    There are three problems you might run into: your GPU and its RAM, your display drivers and your operating system.

Depending on these things, photoshop might automatically have OpenGL off.  For example, my laptop has integrated graphics, which doesn’t have the power to support OpenGL.  You need at least 128 MB of RAM on a GPU that supports it, with installed display drivers that also support it.  You can find the latest drivers or support information on the site of your graphics card’s manufacturer.

OpenGL might also be deselected by default because of your operating system.  This is the case for Windows XP 32 bit, even though it was tested and supported, as well as the 64 bit version, because it was not thoroughly tested.  By turning on OpenGL with a system that might not fully support it, you risk instability and crashes.

If you want all the features to photoshop and are confident that your system can handle OpenGL, just go to Edit (for Windows, Photoshop for Mac)->Preferences->Performance->Enable OpenGL Drawing
