Verifica del supporto delle funzionalità hardware
Questa sezione illustra come verificare il supporto per formato per hardware a livello di funzionalità Direct3D usando le chiamate API.
Per D3D11, usare ID3D11Device::CheckFormatSupport a livello di codice per verificare le informazioni nelle sezioni precedenti. Per D3D12 usare ID3D12::CheckFeatureSupport.
