I'm pretty sure there was a button to tell the program to use Open GL all the time for parts of the software that use Open GL. I upgraded my car, or so I thought, from an ATi 5670 to a 6790 and now the button is gone.
There used to be the 'Open GL' in the Composition tab and now I don't see the button to turn it on.
Is this because of my card?
AH!!! there it is in the first few mins of the vid. The 'fast previews' button. My bad. I called it the Open GL button because the 'Open GL' logo/sign would come up in the composition window.
I feel like a tard now.
