Not a shame for game developers. It&#x27;s nice to have some ability to predict that the failure modes where cards diverge from specification will tend to diverge along the same paths, because they&#x27;re made by the same vendor.<p>Granted, it&#x27;d be preferable to live in a world where the drivers and hardware are open and inspectable (so you don&#x27;t have to debug graphics issues as a black-box problem), but we&#x27;ve never lived in that world and between the likelihood of AMD&#x27;s initiative taking root and a de-facto Nvidia monopoly, I&#x27;d rather have the monopoly.
