Possible to detect prohibited graphics hardware acceleration

Posted: 09-26-2008, 08:10 AM
I read in a lot of places that disabling the graphics hardware acceleration
might be forbidden with Windows Vista.
I also have a computer/graphics card like this: the slider/option in
"Troubleshooting" is missing and it says changing this setting is forbidden
by the driver.

My question: How can I detect programmatically that disabling the hardware
acceleration is prohibited?

This is useful for hiding the respective option in our software in this case.

Thank you in advance
Ulrich

Hi Ulrich,

You might try posting again in Microsoft.public.development.device.drivers -
those folks tend to be more experienced in questions like this.
