I am on Windows XP SP3, NVIDIA 8800GTS. The OPENGL Drawing in Photoshop CS4 works fine, but a lot of times, when i start photoshop, it'll say that OPENGL Drawing is disabled and i'll have to go in to preferences and re-endabe and restart photoshop again to get it working. Please help, it's really annoying
Try setting the 3D settings to Performance (rather than Quality) in the NVIDIA Control Panel.
