Compania Crytek a dezv\u0103luit detalii despre recentul s\u0103u demo de ray tracing \u00een timp real pe placa video Radeon RX Vega 56. Amintim c\u0103, \u00een mijlocul lunii martie a acestui an, dezvoltatorul a publicat un video \u00een care a demonstrat func\u021bionarea ray tracing-ului \u00een timp real pe motorul CryEngine 5.5 folosind o plac\u0103 video AMD.<\/p>\n

La momentul public\u0103rii videoclipului, Crytek nu a dezv\u0103luit detalii despre nivelul de performan\u021b\u0103 al Radeon RX Vega 56 \u00een demonstra\u021bia Neon Noir. Acum, dezvoltatorii au \u00eemp\u0103rt\u0103\u0219it detalii: placa video a reu\u0219it s\u0103 asigure, \u00een medie, 30 FPS la rezolu\u021bia Full HD (1920 \u00d7 1080 pixeli). De asemenea, s-a men\u021bionat c\u0103, dac\u0103 se reduce de dou\u0103 ori calitatea\/intensitatea ray tracing-ului, aceea\u0219i unitate de procesare grafic\u0103 poate oferi \u0219i 40 FPS la rezolu\u021bia QHD (2560 \u00d7 1440 pixeli).<\/p>\n

\"Crytek<\/p>\n

\u00cen demonstra\u021bia Neon Noir, ray tracing-ul este folosit pentru a construi reflec\u021bii \u0219i refrac\u021bii de lumin\u0103. Este important de men\u021bionat c\u0103 exist\u0103 cu adev\u0103rat multe reflec\u021bii, iar placa video Radeon RX Vega 56 a reu\u0219it s\u0103 le gestioneze, chiar \u0219i f\u0103r\u0103 o logic\u0103 specializat\u0103 pentru accelerarea ray tracing-ului, precum nucleele RT. Reamintim c\u0103 \u00een prezent aceast\u0103 plac\u0103 video AMD face parte din solu\u021biile de segment mediu.<\/p>\n

Secretul succesului este simplu: ray tracing-ul \u00een demonstra\u021bia Crytek se bazeaz\u0103 pe voxeluri. Aceast\u0103 abordare necesit\u0103 mult mai pu\u021bin\u0103 putere de calcul dec\u00e2t tehnologia NVIDIA RTX. Datorit\u0103 acestui lucru, placa video nu doar din segmentul de top, ci \u0219i din segmentul mediu de pre\u021b poate construi imagini de calitate folosind ray tracing, indiferent dac\u0103 au sau nu o logic\u0103 specializat\u0103 pentru astfel de sarcini.<\/p>\n

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

Cu toate acestea, Crytek subliniaz\u0103 c\u0103 nucleele RT specializate pot accelera semnificativ ray tracing-ul. Mai mult dec\u00e2t at\u00e2t, pentru utilizarea acestora cu tehnologiile Crytek nu exist\u0103 obstacole, deoarece pl\u0103cile video GeForce RTX accept\u0103 Microsoft DXR. Cu o optimizare corect\u0103, aceste acceleratoare pot oferi cea mai bun\u0103 calitate a ray tracing-ului \u00een demonstra\u021bia Neon Noir, chiar \u0219i la rezolu\u021bia 4K (3840 \u00d7 2160 pixeli). Spre compara\u021bie, GeForce GTX 1080 are o performan\u021b\u0103 de dou\u0103 ori mai mic\u0103. A\u0219adar, GeForce RTX nu ofer\u0103 noi posibilit\u0103\u021bi \u00een motorul CryEngine, dar asigur\u0103 o performan\u021b\u0103 \u0219i o detaliere mai bune.<\/p>\n

\"Crytek<\/p>\n

La final, dezvoltatorii Crytek au men\u021bionat c\u0103 exist\u0103 multe avantaje pentru utilizarea ray tracing-ului \u00een timp real datorit\u0103 API-urilor moderne precum DirectX 12 \u0219i Vulkan. Totul se datoreaz\u0103 faptului c\u0103 acestea ofer\u0103 acces sc\u0103zut la \u201ehardware\u201d, ceea ce permite o optimizare mai bun\u0103 \u0219i utilizarea tuturor resurselor pentru munca intensiv\u0103 cu ray tracing.<\/p>\n
