Hi, one or more nvidia sdk demos using instancing.

Mirek

Stefan Dösinger napsal(a):
Stumbled uppon that while reading up instancing. This is a functionality technically required for all d3d9 drivers. The new functionality is not really tested because I have no app that really needs this, but it should not cause issues with games not using stream offsets.
