1. Re: Forcing OpenGL
Chris Cox Jul 1, 2011 4:20 PM (in response to AcidicInk)Forcing GL to enable is just a diagnostic/debugging tool for video card makers.
It is not something that an end user should be doing -- the video card driver has told Photoshop that it is not capable of the task, so trying to force it is a really bad idea.

That's understandable.
So I suppose the more important problem is:
Why isn't it working by default?
Less than 2 weeks ago this machine was performing wonderfully with OpenGL, in a 32bit enviroment... with the exact same hardware.
Rolled it to a 64bit in order to expand the available memory... and suddenly it's not playing nice.
The FireGL V3750 is on the list of supported cards.
I have tried not only the most up-to-date drivers available from AMD... but also various older releases.
Nothing seems to be working.
Is the 64bit XP an issue?

Because something in your driver is telling Photoshop that it doesn't work.
Yes, XP64 is a big issue -- lots of things don't work correctly on XP64, including OpenGL. We highly recommend moving to Windows 7 64 bit.

That helps quite a bit.
