- AMD There is no documented way to detect the support for this feature I
could find, but it said to be available since long ago on all ATI & AMD cards.
FWIW the usual AMD "spec" on the d3d9 hacks (which I have around in the form of a "Advanced DX9 Capabilities for ATI Radeon Cards_v2.pdf" file) simply says that it's always supported on d3d9+ cards.
