I installed photoshop cs5 extended then I enabled OpenGL Drawing from Edit>Preference>Performance
My VGA Card is HD4850 it supports OpenGL 2.1 Link from manufacturer . I installed the last driver for it
Processor is Intel Q9550.
But the problem is : the 3D Menu is not activated so how to enable it ?
Thanks in advance

But what are the settings? You can install drivers all day - if there is a single wrong option set somewhere, it will prevent OpenGL from working. I suggest you reset the driver to factory defaults and let it auto-configure again on next system startu-up. that is usually the safest way. If you use multiple monitors, try running with one monitor only, especially if the monitors are not identical. This is a quite common limitation, since it will force the card to spend much more resources generating two separate outputs with different settings....
Thanks for help
