I-NVIDIA DLSS, ubuchwepheshe obususelwa kusikrini esigcwele obususelwa kumshini wokulwa ne-aliasing obusebenzisa ama-tensor cores amakhadi wezithombe ze-GeForce RTX, ithuthuke kakhulu ngokuhamba kwesikhathi. Ekuqaleni, lapho usebenzisa i-DLSS, kwakuvame ukufiphala okubonakalayo kwesithombe. Nokho, ku-movie entsha ye-sci-fi action Control evela ku-Remedy Entertainment, ungabona ukuqaliswa okungcono kakhulu kwe-DLSS kuze kube manje. Muva nje i-NVIDIA Yakhiwe kanjani i-algorithm ye-DLSS Yokulawula.
Ngesikhathi socwaningo, inkampani ithole ukuthi izinto zobuciko ezithile zesikhashana, ebezithathwa njengamaphutha, zingasetshenziswa ngempumelelo ukwengeza imininingwane esithombeni. Ngemva kokukuqonda lokhu, i-NVIDIA yaqala ukusebenza ngemodeli entsha yocwaningo lwe-AI eyasebenzisa izinto zobuciko ezinjalo ukuze idale kabusha imininingwane ebikade ingekho esithombeni sokugcina. Ngosizo lwemodeli entsha, inethiwekhi ye-neural yaqala ukuzuza impumelelo enkulu futhi yakhiqiza ikhwalithi yesithombe ephezulu kakhulu. Kodwa-ke, iqembu bekumele lisebenze kanzima ukuze lenze kahle imodeli ngaphambi kokuyingeza emdlalweni. I-algorithm yokugcina yokucubungula isithombe yenze kwaba nokwenzeka ukuzuza ukukhuphuka kwezinga lozimele kufika ku-75% kumamodi asindayo.
Ngokuvamile, i-DLSS isebenza ngomgomo olandelayo: igeyimu inikezwa ngezinqumo ezimbalwa, bese, ngokusekelwe kumapheya anjalo ezithombe, inethiwekhi ye-neural iqeqeshelwa ukuguqula isithombe esinesinqumo esiphansi sibe phezulu. Kumdlalo ngamunye kanye nesinqumo ngasinye, udinga ukuqeqesha imodeli yakho isikhathi eside, ngakho ngokuvamile i-DLSS itholakala kuphela ezimodini ezinzima kakhulu (isibonelo, ngemiphumela yokulandelela imisebe), ehlinzeka ngokusebenza okwamukelekayo kuzo.
I-NVIDIA iphawule ukuthi ngisho nenguqulo entsha nethuthukisiwe ye-DLSS isashiya indawo yokuthuthukiswa nokuthuthukiswa. Isibonelo, uma usebenzisa i-DLSS ku-720p ekulawuleni, amalangabi abukeka kabi kakhulu kunaku-1080p. Ama-artifact afanayo abonwa kwezinye izinhlobo zokunyakaza kuhlaka.
Ngakho-ke, ochwepheshe bazoqhubeka nokuthuthukisa imodeli yokufunda yomshini ukuze bathole imiphumela emangalisa nakakhulu. Futhi baze babonisa inguqulo yokuqala yemodeli yabo elandelayo ethembisayo ye-DLSS besebenzisa isibonelo sendawo yomlilo wehlathi ku-Unreal Engine 4. Imodeli entsha ikuvumela ukuthi ubuyisele imininingwane emincane efana namalahle nezinhlansi, nakuba isadinga ukuthuthukiswa mayelana nokunikezwa kohlaka. isivinini. Lapho lo msebenzi usuqediwe, abanikazi bamakhadi evidiyo asekelwe ekwakhiweni kwe-Turing bazothola abashayeli abasha abanezindlela ezingcono kakhulu nezisebenza kahle kakhulu ze-DLSS.
