A Microsoft anunciou, no \u00e2mbito do programa de acesso antecipado Windows Insider Preview apresentou<\/a><\/noindex> as APIs atualizadas do DirectX 12 e detalhou as novidades. Esses recursos estar\u00e3o dispon\u00edveis na vers\u00e3o do pr\u00f3ximo ano e incluem tr\u00eas funcionalidades principais.<\/p>\n

\"A<\/p>\n

A primeira funcionalidade diz respeito ao ray tracing. No DirectX 12, ele j\u00e1 existia, mas agora foi ampliado. Em particular, shaders adicionais foram adicionados ao objeto existente de ray tracing PSO (objetos de estado do pipeline). Isso permite aumentar a efici\u00eancia do trabalho.<\/p>\n

Seguindo, devemos mencionar a tecnologia de algoritmos adaptativos ExecuteIndirect. De acordo com a descri\u00e7\u00e3o, essa funcionalidade permite determinar a quantidade de raios na linha do tempo da execu\u00e7\u00e3o da GPU. Finalmente, agora h\u00e1 uma op\u00e7\u00e3o para utilizar uma vers\u00e3o simplificada de ray tracing.<\/p>\n

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

A empresa tamb\u00e9m trabalhou na geometria. Na API DirectX 12, a Microsoft adicionou suporte para shaders de malha (Mesh Shaders). Essa funcionalidade \u00e9 chamada DirectX Sampler. Ela permite identificar quais texturas s\u00e3o mais acess\u00edveis e devem permanecer na mem\u00f3ria. Como resultado, na mem\u00f3ria de v\u00eddeo s\u00e3o armazenados apenas os dados necess\u00e1rios no momento.<\/p>\n

\"A<\/p>\n

Dessa forma, a novidade permitir\u00e1 eliminar os longos tempos de carregamento frustrantes em mundos virtuais. Essa \u00e9 a chamada tecnologia de streaming de texturas.<\/p>\n

\"A<\/p>\n

Para mais detalhes, est\u00e1 descrito<\/a><\/noindex> consulte o blog dos desenvolvedores da Microsoft. Vale ressaltar que, h\u00e1 alguns dias, a AMD se pronunciou de forma positiva sobre o assunto e insinuou a chegada de novas funcionalidades em seus produtos Radeon. Claramente, essas fun\u00e7\u00f5es estar\u00e3o dispon\u00edveis em novas placas de v\u00eddeo de alto desempenho, que se espera sejam lan\u00e7adas em 2020. Espera-se que, entre outras coisas, elas tenham suporte de hardware para ray tracing.<\/a><\/noindex> \ud83e\udd47A Microsoft compartilhou as novidades no DirectX 12: ray tracing simplificado e detalhamento de acordo com a dist\u00e2ncia | ProHoster <\/p>\n
