"How much additional time and effort, above that put into the normal driver development regime, is/has been put into making sure ATi products "fit" into Vista's DRM? Would I get an honest answer if we asked whether you're in favour of the whole DRM thing?

There has been a lot of effort that has gone into supporting the entire DRM strategy, but users shouldn't think of it as taking resources away from working on more "useful" features. DRM is something that the whole industry is moving towards and something we need to support. And no you wouldn't get an honest answer from me ;-) "
