Microsoft ha annunciato il programma Windows Insider preview. ha presentato<\/a><\/noindex> ha aggiornato le API di DirectX 12 e ha dettagliato le novit\u00e0. Queste funzionalit\u00e0 saranno disponibili nella versione del prossimo anno e includono tre caratteristiche principali.<\/p>\n

\"Microsoft<\/p>\n

La prima novit\u00e0 riguarda il ray tracing. In DirectX 12 era gi\u00e0 presente, ma ora \u00e8 stato ampliato. In particolare, sono stati aggiunti shader aggiuntivi all'oggetto di stato del pipeline di ray tracing (PSO). Questo aumenter\u00e0 l'efficienza delle operazioni.<\/p>\n

Inoltre, vale la pena menzionare la tecnologia degli algoritmi adattivi ExecuteIndirect. Secondo la descrizione, questa funzionalit\u00e0 consente di determinare il numero di raggi nel timeline di esecuzione della GPU. Infine, \u00e8 stata introdotta una versione semplificata del ray tracing.<\/p>\n

<\/center><\/p>\n

La Microsoft ha lavorato anche sulla geometria. Nella API DirectX 12, \u00e8 stato aggiunto il supporto per gli shader delle mesh (Mesh Shaders). Questa funzione \u00e8 chiamata DirectX Sampler. Essa permette di identificare quali texture sono pi\u00f9 frequentemente accessibili e devono rimanere in memoria. Di conseguenza, nella memoria video vengono conservati solo i dati necessari in quel momento.<\/p>\n

\"Microsoft<\/p>\n

In questo modo, la novit\u00e0 permetter\u00e0 di eliminare le fastidiose lunghe attese per il caricamento dei mondi virtuali. Questa \u00e8 nota come tecnologia di streaming delle texture.<\/p>\n

\"Microsoft<\/p>\n

Maggiore dettaglio su tutto ci\u00f2 \u00e8 descritto<\/a><\/noindex> nel blog degli sviluppatori di Microsoft. Vale la pena notare che pochi giorni fa, AMD ha espresso un parere positivo su questo argomento<\/a><\/noindex> e ha accennato a un imminente arrivo di nuove funzionalit\u00e0 nei prodotti Radeon. \u00c8 chiaro che queste appariranno gi\u00e0 nelle nuove schede grafiche di punta, che si prevede saranno rilasciate nel 2020. A queste sar\u00e0 attribuita, tra l'altro, il supporto hardware per il ray tracing. <\/p>\n
