Prise en charge de la fonctionnalité de vérification du matériel
Cette section explique comment case activée sur la prise en charge du format pour le matériel de niveau de fonctionnalité Direct3D à l’aide d’appels d’API.
Pour D3D11, utilisez ID3D11Device::CheckFormatSupport pour vérifier par programmation les informations des sections précédentes. Pour D3D12, utilisez ID3D12::CheckFeatureSupport.
