We've launched a 3D windows app for distribution at another company, but we encountered some problems with running it on their tightly controlled set of computers. The IT group set up all of the computers there to the same policy where graphics hardware acceleration has been mostly disabled (the hardware acceleration slider is set to disable DirectDraw and Direct3D and cannot be changed by the user).
The video card in each machine, the Mobile Intel GMA X4500HD, is perfectly capable of running 3D applications, but it seems like they've purposefully left the video card just running idle.
I just want to know what could be the reason for such a policy. They mentioned to us that it may have been set this way for compatibility with some videos released a while ago, but it seems like this setting should be a last resort. Without having personal direct access to whoever had set this policy, I can only just make guesses.
