Microsoft introducerer i forbindelse med Windows Insider preview-programmet pr\u00e6senterede<\/a><\/noindex> de opdaterede API'er til DirectX 12 og giver en detaljeret forklaring af de nye funktioner. Disse muligheder vil v\u00e6re tilg\u00e6ngelige i udgivelsen n\u00e6ste \u00e5r og inkluderer tre hovedfunktioner.<\/p>\n

\"Microsoft<\/p>\n

Den f\u00f8rste funktion handler om ray tracing. Den var oprindeligt til stede i DirectX 12, men er nu blevet udvidet. Specifikt er der blevet tilf\u00f8jet ekstra shader til det eksisterende ray tracing PSO (pipeline state object). Dette \u00f8ger effektiviteten.<\/p>\n

Dern\u00e6st er der teknologien for adaptive ExecuteIndirect-algoritmer. If\u00f8lge beskrivelsen g\u00f8r denne mulighed det muligt at bestemme antallet af str\u00e5ler p\u00e5 GPU'ens k\u00f8replan. Endelig er der blevet mulighed for at bruge en lettere version af ray tracing.<\/p>\n

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

Virksomheden har ogs\u00e5 arbejdet med geometrien. I API'et DirectX 12 har Microsoft tilf\u00f8jet st\u00f8tte til mesh shaders. Denne funktion kaldes DirectX Sampler. Den g\u00f8r det muligt at bestemme, hvilke teksturer der er mest tilg\u00e6ngelige, og som b\u00f8r forblive i hukommelsen. Resultatet er, at kun de data, der er n\u00f8dvendige her og nu, opbevares i videohukommelsen.<\/p>\n

\"Microsoft<\/p>\n

Dermed vil denne nyhed muligvis eliminere de irriterende lange indl\u00e6sninger af virtuelle verdener. Dette er den s\u00e5kaldte teknologi til streaming af teksturer.<\/p>\n

\"Microsoft<\/p>\n

Alt dette er beskrevet<\/a><\/noindex> i Microsofts udviklerblog. Det er v\u00e6rd at bem\u00e6rke, at AMD for nogle dage siden positivt udtrykte sig<\/a><\/noindex> om dette emne og antydede, at nye funktioner snart vil komme til Radeon-produkterne. Det er \u00e5benlyst, at de vil blive lanceret i de nye topmodeller af grafikkort, som forventes at komme i 2020. De siges at have hardwareunderst\u00f8ttelse af ray tracing blandt andet. <\/p>\n
