use software rendering instead of GPU rendering in ie9

Hi there,

I have copied the admx and adml files from my computer where I have ie9 installed to %systemroot%\sysvol\domain\policies\PolicyDefinitions and %systemroot%\sysvol\domain\policies\PolicyDefinitions\en-us.

However when I try and find the setting "use software rendering instead of GPU rendering" shown here: http://www.trishtech.com/internet/use_software_rendering_in_internet_explorer_9.php - I cannot find it.

Where do I look for that setting?

Thanks,

Steve.
