Isikhathi esiningi sesidlulile kusukela amakhadi okuqala ezithombe asuselwa kuma-chips omndeni we-Turing avele emakethe. Okwamanje, ikhathalogu yama-accelerator "aluhlaza" ihlanganisa amamodeli amane akwazi ukwenza ukulandelela ama-ray ngesikhathi sangempela, kodwa i-NVIDIA ngeke ime lapho - kakade maphakathi no-Ephreli, amakhadi wevidiyo ochungechunge lwe-GeForce GTX 16 kanye nama-accelerator amaningi kuma-chips e-Pascal. izosekela ukuxhumana kwe-DXR ne-Vulkan RT. eqala nge-GeForce GTX 1060 nge-RAM engu-6 GB. Kodwa imidlalo esivele isebenzisa ubuchwepheshe be-DXR noma i-DLSS esekelwe ekufundeni komshini nama-tensor cores we-Turing architecture isengabalwa eminwe yesandla esisodwa. Futhi ngakolunye uhlangothi - amaphrojekthi azayo anamakhono anjalo.
Inkazimulo yamaphayona isivele iye e-Battlefield V kanye ne-Final Fantasy XV, futhi muva nje i-Metro Exodus iye yaduma. I-Shadow of the Tomb Raider yabuyela emuva ngoSepthemba wonyaka odlule, futhi abalandeli abaningi bochungechunge abazange balinde kuze kube yilapho iqembu le-Eidos, ngokubambisana neCrystal Dynamics, linikeza umdlalo ngokusekelwa kwe-DXR ne-DLSS. Asizange silinde nalapho sikhipha isivivinyo seqembu samakhadi evidiyo ku-Shadow of the Tomb Raider. Kodwa manje sekuvele isibuyekezo esithenjisiwe, okusho ukuthi umsebenzi wethu ngalo mdlalo awukakaqedi.
Izibonelo zokulandela imisebe
Ngo-Agasti odlule, i-NVIDIA ibonise ukulandelana okumangazayo okuvela ku-Shadow of the Tomb Raider, lapho ukulandelela kwe-ray kuguqula isithombe ngokoqobo. Kepha kulabo badlali abangajahi esitolo ukuthola amakhadi evidiyo esizukulwane esilandelayo noma abayekele ukujwayelana nomdlalo kuze kube isiqephu sakamuva esisekelwa yi-DXR, kungcono ukulungisa lokho abakulindele. Phela, igama elithi Ray Tracing in Shadow of the Tomb Raider kusukela ekuqaleni lalibhekisela kuphela ethunzini lezinto ezitholakala emisebeni yemithombo yokukhanya eqondile.
Uma kucatshangelwa ukuthi ingxenye enhle yezigigaba zikaLara Croft zenzeka ngaphansi komhlaba, iShadow of the Tomb Raider iqukethe izigcawu eziningi ezifanayo. Ngaphandle kwe-DXR, injini isebenzisa amamephu ethunzi ashukumisayo ukuze inikeze imiphumela yokukhanya okuqondile. Le ndlela ithi akufane nokulandela umkhondo kulawo mamephu ethunzi akhiqizwa ngokuhlukanisa indawo yesehlakalo kumbono ohambisana nomthombo wokukhanya, kodwa inobubi obaziwayo. Ngakho-ke, amamephu ethunzi awanembile kakhulu; asebenza kuphela nemithombo yokukhanya yamaphuzu futhi awakhi ama-silhouette anezinhlaka ezithambile ngaphandle kokusebenza kokufiphala konqenqema okwengeziwe. Futhi ukuze ulondoloze izinsiza zekhompiyutha, njengomthetho, izinto ezikhethiwe kuphela ezibekwe emabalazweni ethunzi. Ukulandelela uRay akunazo lezi zinto eziphezulu, futhi ezimeni ezifanele i-Shadow of the Tomb Raider ishintsha kakhulu - into okufanele ibuyekezwe kulabo asebevele bawushayile umdlalo ukuze bazibonele.
Kepha maye, umthelela we-DXR ku-Shadow of the Tomb Raider ukhawulelwe emithonjeni yokukhanya eqondile. Ukukhanya okuveziwe kusasetshenziswa kusetshenziswa izindlela ezimile, "okubhakwa" kusihleli semephu, ngesengezo esiguqukayo ngendlela ye-Ambient Occlusion. Ngemuva kwe-Metro Exodus, lapho abathuthukisi beshintshe yonke imodeli yokukhanya yomhlaba wonke ekulandeleleni i-ray, indlela ye-Shadow of the Tomb Raider's half-hearted isivele inzima ukuyihlanganisa. Ngaphezu kwalokho, kusukela kuzithombe-skrini kulula ukubona ukuthi ukujula kwesithunzi kushintsha kangakanani kuye ngezilungiselelo ze-DXR. Kwezinye izigcawu kunzima ukubona umehluko phakathi kokulandela umkhondo weleveli emaphakathi namamephu ethunzi ajwayelekile. Ngaphezu kwalokho, ngisho nakumazinga aphezulu ekhwalithi ye-DXR, ama-silhouette anyathelayo ayabonakala njengomphumela wokuminyana kwe-beam ephansi.

Ikhwalithi Yesithombe: DLSS vs TAA
Ukulandelela uRay, ngisho nangefomethi elinganiselwe, njengoba kwenziwa ku-Shadow of the Tomb Raider, kuthinta kakhulu ukusebenza kwe-GPU, futhi lokhu kakade kuyiphrojekthi enzima kakhulu kuzilungiselelo zekhwalithi yezithombe eziphezulu. Ukunxephezela ukushaya okungagwemeki kumazinga ozimele, abathuthukisi begeyimu bethule ukwesekwa kwe-DLSS ngesikhathi esifanayo ne-DXR. Sesivele sibhale ngaphezu kwesisodwa mayelana nobuchwepheshe bobunikazi be-NVIDIA, obuvumela i-GPU ukuthi inikeze ngesinqumo esincishisiwe bese isikala ifreyimu isebenzisa inethiwekhi ye-neural kuma-tensor cores we-Turing architecture. Kodwa-ke, ulwazi olusebenzayo olunikezwe i-Battlefield V, Final Fantasy XV kanye ne-Metro Eksodos sekuvele kucekele phansi noma yikuphi ukukhohlisa mayelana nekhwalithi ye-DLSS esigabeni sokuqala sokusatshalaliswa kwayo. Kule midlalo emithathu yokuqala, i-Final Fantasy XV kuphela enomphumela we-DLSS ofana nokunikeza okuqondile ekuxazululeni okuqondiwe, futhi nalapho kunezixwayiso eziningi.
Akubuzwa, besingalindele imiphumela evelele evela ku-DLSS ku-Shadow of the Tomb Raider? Nokho, umdlalo usinike isimanga esimnandi. Kumashothi ambalwa esiwashuthe sisebenzisa i-DLSS ne-TAA, indlela esetshenziswa kakhulu futhi engadingi mkhawulo yesikrini esigcwele sokulwa ne-aliasing, kunzima ukubona noma yimuphi umehluko ekucaciseni uma uthi nhlá. I-DLSS inhle kakhulu ekuthwebuleni imininingwane yokuthungwa ezindaweni ezinkulu. Ngisho nezinto ezifana namahlamvu esitshalo nezinwele cishe azinakho ukufiphala. Ukuze uqhathanise, nazi izithombe-skrini ezifanayo ezithathwe ngemodi engu-1440p futhi zivele zikhuphukele ekuxazululeni okuhlosiwe okungu-2160p kusetshenziswa injini yegeyimu (ukwenza lokhu, udinga ukukhubaza inketho yemodi yesikrini esigcwele okukhethekile).

Kodwa-ke, sesivele sikwazile ukwenza isiqiniseko sokuthi kuyo yonke imidlalo esebenzisa i-DLSS, awekho amanethiwekhi amabili afanayo we-neural angatholakala. I-algorithm ehambisana ne-Shadow of the Tomb Raider inezingqinamba esingakaze sihlangabezane nazo ngaphambili. I-DLSS inenkinga ngezakhi zesithombe ezinemigqa emincane emincane eminingi ebonakala ibekwe phezulu phezu kokuthungwa okusobala - izikhulumi zebhayisikili, i-ivy ezindongeni zesakhiwo, nokunye okunjalo. Lezi zindawo zohlaka zibukeka sengathi i-DLSS ayizami ngisho nokukhulisa ukulungiswa.
Ngaphezu kwalokho, ezigcawini eziyinkimbinkimbi (ngokwesibonelo, ekujuleni kwehlathi), inethiwekhi ye-neural kwesinye isikhathi iyadideka futhi iqale ukufiphalisa izinto ezicutshungulwa ngenye indlela ngereferensi ecacile (njengezingubo nezinwele zomlingisi oyinhloko). Lapho ikhamera ihamba ngokucijile, amaphethini angamanga avela ophahleni lukathayela (noma kunjalo, akunakwenzeka ukuzibona zinyakaza). Okokugcina, i-DLSS ithuthukisa kakhulu ukugqama kukonke, ngokunganaki okuqukethwe kohlaka. Kodwa lokhu kuyi-nitpicking. Sekukonke, i-Shadow of the Tomb Raider ithole imiphumela engcono kakhulu yemidlalo emine ngokusekelwa kwe-DLSS - sincoma ngokuqinile ukunika amandla le nketho, ikakhulukazi ku-2160p kuhlanganiswe ne-DXR.

Ukuhlolwa kokusebenza kwenziwa kusetshenziswa ibhentshimakhi eyakhelwe ngaphakathi ye-Shadow ye-Tomb Raider enazo zonke izinketho zezithombe ngamavelu aphezulu (ngaphandle kwe-anti-aliasing yesikrini esigcwele kanye ne-DXR, esihluka ngayo ekuhlolweni). Izilinganiso zozimele ezimaphakathi nezincane zithathwa ohlwini lwezikhathi zokunikezwa zozimele abangabodwana, igeyimu eyibhala efayeleni lemiphumela.
Izinga lozimele elimaphakathi emashadini liwukuphambene nesikhathi esimaphakathi sokunikezwa kozimele. Ukuze ulinganisele isilinganiso esincane sozimele, inani lozimele elakhiwe kusekhondi ngalinye lokuhlolwa liyabalwa. Kulolu hlu lwezinombolo, inani elihambisana nephesenti loku-1 lokusatshalaliswa liyathathwa.
