Crytek har afsl\u00f8ret detaljer om deres nylige demonstration af realtids str\u00e5lesporing p\u00e5 grafikkortet Radeon RX Vega 56. Husk, at udvikleren i midten af marts i \u00e5r offentliggjorde en video, hvor de demonstrerede realtids str\u00e5lesporing p\u00e5 CryEngine 5.5 ved brug af et AMD grafikkort.<\/p>\n

Ved offentligg\u00f8relsen af videoen afsl\u00f8rede Crytek ikke detaljer om ydeevnen af Radeon RX Vega 56 i demonstrationen Neon Noir. Nu har udviklerne delt detaljerne: grafikkortet kunne i gennemsnit opn\u00e5 30 FPS i Full HD-opl\u00f8sning (1920 \u00d7 1080 pixel). Det blev ogs\u00e5 bem\u00e6rket, at hvis kvaliteten\/intensiteten af ray tracing halveres, kan det samme grafiske accelerator levere 40 FPS i QHD-opl\u00f8sning (2560 \u00d7 1440 pixel).<\/p>\n

\"Crytek<\/p>\n

I Neon Noir-demonstrationen anvendes str\u00e5lesporing til at generere refleksioner og lysbrydninger. Det er v\u00e6rd at bem\u00e6rke, at der virkelig er mange refleksioner, og at Radeon RX Vega 56 kunne h\u00e5ndtere dem, selv uden specialiseret logik til at accelerere str\u00e5lesporing som RT-kernene. Husk, at dette AMD grafikkort i \u00f8jeblikket klassificeres som et produkt i mellemprisklassen.<\/p>\n

N\u00f8glen til succesen er enkel: str\u00e5lesporing i Cryteks demonstration er baseret p\u00e5 voxel-teknologi. Denne tilgang kr\u00e6ver betydeligt mindre beregningskraft end NVIDIA RTX-teknologien. P\u00e5 grund af dette kan grafikkort i b\u00e5de h\u00f8j- og mellemprisklasser opbygge kvalitetsbilleder ved hj\u00e6lp af str\u00e5lesporing, uafh\u00e6ngigt af om de har specialiseret logik til s\u00e5danne opgaver eller ej.<\/p>\n

\n\"Crytek<\/p>\n

Crytek bem\u00e6rker dog, at specialiserede RT-kerner kan betydeligt accelerere ray tracing. Is\u00e6r er der ikke nogen hindringer for at bruge dem med Cryteks teknologier, da GeForce RTX-grafikkort underst\u00f8tter Microsoft DXR. Med den rette optimering kan disse acceleratorer sikre maksimal kvalitet i ray tracing i demonstrationen Neon Noir selv i 4K-opl\u00f8sning (3840 \u00d7 2160 pixel). Til sammenligning har GeForce GTX 1080 halvt s\u00e5 h\u00f8j ydeevne. S\u00e5 GeForce RTX giver ikke nye muligheder i CryEngine, men sikrer bedre ydeevne og detaljer.<\/p>\n

\"Crytek<\/p>\n

Til sidst bem\u00e6rkede udviklerne fra Crytek, at moderne API'er som DirectX 12 og Vulkan ogs\u00e5 giver mange fordele ved brugen af ray tracing i realtid. Det skyldes, at de giver bred, lavniveau adgang til \"hardwaren\", hvilket muligg\u00f8r bedre optimering og udnyttelse af alle ressourcer til kr\u00e6vende ray tracing-opgaver.<\/p>\n
