Od dzisiaj \u015bledzenie promieni w czasie rzeczywistym jest wspierane nie tylko przez karty graficzne GeForce RTX, ale r\u00f3wnie\u017c przez niekt\u00f3re karty GeForce GTX 16xx i 10xx.

Lista kart graficznych obs\u0142uguj\u0105cych ray tracing w czasie rzeczywistym zosta\u0142a wzbogacona o karty GeForce GTX 1660 Ti i GTX 1660, Titan Xp i Titan X (Pascal), GeForce GTX 1080 Ti i GTX 1080, GeForce GTX 1070 Ti i GTX 1070 oraz wersj\u0119 GeForce GTX 1060 z 6 GB pami\u0119ci. Oczywi\u015bcie, ray tracing b\u0119dzie dzia\u0142a\u0107 tutaj z pewnymi ograniczeniami w por\u00f3wnaniu do kart graficznych GeForce RTX. Im starsza karta graficzna, tym ograniczenia b\u0119d\u0105 silniejsze. Jednak fakt, \u017ce w\u0142a\u015bciciele nawet najmocniejszej GeForce GTX 1060 b\u0119d\u0105 mogli \u201edotkn\u0105\u0107\u201d nowej technologii, jest z pewno\u015bci\u0105 pocieszaj\u0105cy.<\/p>\n

Podczas gdy karty graficzne GeForce RTX maj\u0105 wyspecjalizowane bloki obliczeniowe (rdzenie RT) zapewniaj\u0105ce przyspieszenie sprz\u0119towe \u015bledzenia promieni, karty graficzne GeForce GTX takich element\u00f3w po prostu nie maj\u0105. Dlatego w nich \u015bledzenie promieni jest realizowane za pomoc\u0105 rozszerzenia DXR dla Direct3D 12, a przetwarzaniem promieni zajmuj\u0105 si\u0119 zwyk\u0142e shadery obliczeniowe na macierzy rdzeni CUDA.<\/p>\n

Takie podej\u015bcie oczywi\u015bcie nie pozwoli kartom na procesorach graficznych Pascal i starszych Turing na osi\u0105gni\u0119cie takiego samego poziomu wydajno\u015bci przy \u015bledzeniu promieni, na jaki sta\u0107 modele serii GeForce RTX. Opublikowane przez NVIDIA slajdy z wynikami test\u00f3w wydajno\u015bci r\u00f3\u017cnych kart graficznych przy u\u017cyciu \u015bledzenia promieni pokazuj\u0105 ogromn\u0105 r\u00f3\u017cnic\u0119 mi\u0119dzy modelami GeForce RTX i GeForce GTX.<\/p>\n

Na przyk\u0142ad w grze Metro Exodus, gdzie \u015bledzenie promieni zapewnia globalne o\u015bwietlenie, \u017cadna z kart graficznych GeForce GTX nie by\u0142a w stanie zapewni\u0107 akceptowalnej liczby klatek na sekund\u0119 (FPS). Nawet flagowiec zesz\u0142ej generacji GeForce GTX 1080 Ti uzyska\u0142 jedynie 16,4 kl.\/s. Z kolei w Battlefield V, gdzie \u015bledzenie promieni odpowiada tylko za odbicia, flagowiec generacji Pascal osi\u0105gn\u0105\u0142 jednak 30 FPS.<\/p>\n

\"\u015aledzenie <\/p>\n

Jednak NVIDIA testowa\u0142a karty graficzne przy najwy\u017cszych ustawieniach graficznych, z maksymaln\u0105 intensywno\u015bci\u0105 ray tracingu i w rozdzielczo\u015bci 2560 \u00d7 1440 pikseli. To znaczy, \u017ce warunki, delikatnie m\u00f3wi\u0105c, by\u0142y ma\u0142o sprzyjaj\u0105ce: ta sama GeForce GTX 2060 w Metro Exodus osi\u0105ga\u0142a \u015brednio nieco ponad 34 klatki na sekund\u0119. Aby osi\u0105gn\u0105\u0107 \u201egrywalny\u201d FPS na starszych kartach graficznych, mo\u017cna b\u0119dzie obni\u017cy\u0107 rozdzielczo\u015b\u0107 i jako\u015b\u0107 grafiki. Jednak przede wszystkim na ich wydajno\u015b\u0107 wp\u0142yn\u0105 ustawienia intensywno\u015bci ray tracingu.<\/p>\n

\"\u015aledzenie<\/p>\n

Przypominamy, \u017ce obecnie z technologi\u0105 \u015bledzenia promieni mo\u017cna zapozna\u0107 si\u0119 w trzech grach: Battlefield V, Metro Exodus i Shadow of the Tomb Raider. Jest r\u00f3wnie\u017c dost\u0119pna w trzech demach: Atomic Heart, Justice i Reflections. Zar\u00f3wno w grach, jak i w demonstracjach oferowane s\u0105 r\u00f3\u017cne warianty wykorzystania \u015bledzenia promieni. Gdzie\u015b odpowiada za odbicia i cienie, a gdzie indziej za globalne o\u015bwietlenie.<\/p>\n
