Nkhani yatsopano: Kuyesa kufufuza kwa ray ndi DLSS mu Shadow of the Tomb Raider

Nthawi yayitali yadutsa kuyambira pomwe makhadi ojambulira oyamba otengera tchipisi tabanja la Turing adawonekera pamsika. Pakadali pano, kabukhu la "green" accelerators limaphatikizapo mitundu inayi yomwe imatha kutsata ray munthawi yeniyeni, koma NVIDIA siyiyima pamenepo - kale pakati pa Epulo, makadi amakanema a mndandanda wa GeForce GTX 16 ndi ma accelerator ambiri pa tchipisi cha Pascal. ithandizira zolumikizira za DXR ndi Vulkan RT kuyambira ndi GeForce GTX 1060 yokhala ndi 6 GB RAM. Koma masewera omwe amagwiritsa ntchito kale ukadaulo wa DXR kapena DLSS kutengera kuphunzira kwamakina ndi ma tensor cores of the Turing achitecture amathanso kuwerengedwa pa zala za dzanja limodzi. Ndipo kumbali ina - mapulojekiti omwe akubwera omwe ali ndi luso lotere.

Ulemerero wa apainiya wapita kale ku Battlefield V ndi Final Fantasy XV, ndipo posachedwa Metro Eksodo yagunda. Shadow of the Tomb Raider idabwereranso golide mu Seputembala chaka chatha, ndipo mafani ambiri pamndandandawu sanadikire mpaka timu ya Eidos, mogwirizana ndi Crystal Dynamics, idapereka masewerawa ndi thandizo la DXR ndi DLSS. Sitinadikire ngakhale titatulutsa mayeso a gulu la makadi a kanema mu Shadow of the Tomb Raider. Koma tsopano zosinthika zolonjezedwa zawonekera, zomwe zikutanthauza kuti ntchito yathu ndi masewerawa sinathe.

Zitsanzo za Ray Tracing

Ogasiti watha, NVIDIA idawonetsa kutsatizana kochititsa chidwi kuchokera ku Shadow of the Tomb Raider, momwe kutsatira ray kumasintha chithunzicho. Koma kwa osewera omwe sathamangira kusitolo kukagula makhadi am'badwo wotsatira kapena asiya kuzolowerana ndi masewerawa mpaka chigamba chaposachedwa ndi chithandizo cha DXR, ndibwino kusintha zomwe akuyembekezera. Kupatula apo, mawu akuti Ray Tracing mu Shadow of the Tomb Raider kuyambira pachiyambi amangotanthauza mithunzi yochokera kuzinthu zomwe zili mu kuwala kwa magwero achindunji.

Poganizira kuti gawo labwino la zochitika za Lara Croft zimachitika mobisa, Shadow of the Tomb Raider ili ndi zithunzi zambiri zofanana. Popanda DXR, injini imagwiritsa ntchito mamapu amithunzi osinthika kuti iwonetse kuyatsa kwachindunji. Njirayi ndi yofanana ndi kutsata mapu amithunzi omwe amapangidwa powonetsa zochitikazo mosiyana ndi momwe zimakhalira ndi gwero la kuwala, koma zimadziwika ndi zovuta zake. Chifukwa chake, mamapu azithunzi sakhala olondola kwambiri; amangogwira ntchito ndi magwero owunikira komanso sapanga ma silhouette okhala ndi maulalo ofewa popanda kugwiritsa ntchito zina zowonjezera. Ndipo kuti mupulumutse zida zamakompyuta, monga lamulo, zinthu zosankhidwa zokha zimayikidwa pamapu amthunzi. Kufufuza kwa Ray kulibe izi, ndipo m'mikhalidwe yoyenera Shadow of the Tomb Raider imasintha kwambiri - chinthu chomwe chili choyenera kubwerezanso kwa iwo omwe adamenya kale masewerawa kuti adziwonere okha.

Koma tsoka, kukhudza kwa DXR mu Shadow of the Tomb Raider kumangokhala ndi magwero owunikira. Kuwala kowunikiridwa kumagwiritsidwabe ntchito pogwiritsa ntchito njira zosasunthika, "zophika" mu mkonzi wa mapu, ndikuwonjezera kwamphamvu mu mawonekedwe a Ambient Occlusion. Pambuyo pa Metro Eksodo, pomwe opanga adasintha mawonekedwe onse owunikira padziko lonse lapansi kuti atsate ray, njira ya Shadow of the Tomb Raider ya theka ndiyovuta kugwirizanitsa. Kuphatikiza apo, kuchokera pazithunzi ndizosavuta kuwona momwe kuzama kwamthunzi kumasinthira kutengera makonda a DXR. Muzinthu zina zimakhala zovuta kuwona kusiyana pakati pa kutsata mulingo wapakatikati ndi mamapu wamba amithunzi. Kuphatikiza apo, ngakhale pamilingo yapamwamba ya DXR, ma silhouette opondapo amawonekera chifukwa cha kutsika kwamitengo.

Ubwino wa Zithunzi: DLSS vs TAA

Kufufuza kwa Ray, ngakhale mumpangidwe wochepa, monga momwe anachitira mu Shadow of the Tomb Raider, kumakhudza kwambiri machitidwe a GPU, ndipo iyi ndi ntchito yovuta kwambiri pazithunzi zapamwamba zazithunzi. Kuti alipire kugunda kosalephereka kumitengo ya chimango, opanga masewerawa adayambitsa kuthandizira kwa DLSS nthawi yomweyo DXR. Talemba kale kangapo zaukadaulo wa eni ake a NVIDIA, womwe umalola GPU kuti ipereke chigamulo chocheperako ndikukulitsa chimangocho pogwiritsa ntchito neural network pamatensor cores a Turing. Komabe, zochitika zothandiza zoperekedwa ndi Battlefield V, Final Fantasy XV ndi Metro Exodus zawononga kale chinyengo chilichonse chokhudza khalidwe la DLSS pachiyambi cha kugawa kwake. Mwa masewera atatu ochita upainiya, Final Fantasy XV yokhayo ili ndi DLSS yotulutsa yofanana ndi kumasulira kwachindunji, ndipo ngakhale ndi chenjezo zambiri.

Mosakayikira, sitinayembekezere zotsatira zabwino kuchokera ku DLSS mu Shadow of the Tomb Raider? Komabe, masewerawa adatipatsa zodabwitsa zodabwitsa. Mu kuwombera pang'ono komwe tidawombera pogwiritsa ntchito DLSS ndi TAA, njira yomwe imagwiritsidwa ntchito kwambiri komanso yosagwirizana ndi mawonekedwe onse, ndizovuta kuzindikira kusiyana kulikonse pakumveka koyamba. DLSS ndiyabwino kwambiri kujambula tsatanetsatane wa mawonekedwe pamalo akulu. Ngakhale zinthu monga masamba a zomera ndi tsitsi zilibe mdima. Poyerekeza, nazi zithunzi zofananira zomwe zidatengedwa mumayendedwe a 1440p ndikungokwera mpaka 2160p chandamale pogwiritsa ntchito injini yamasewera (kuti muchite izi, muyenera kuletsa njira yokhayo yazithunzi zonse).

Komabe, takwanitsa kale kuwonetsetsa kuti m'masewera onse omwe amagwiritsa ntchito DLSS, palibe ma neural network awiri ofanana omwe angapezeke. Algorithm yodziwika ndi Shadow of the Tomb Raider ili ndi zovuta zina zomwe sitinakumanepo nazo. DLSS ili ndi vuto ndi zinthu zazithunzi zokhala ndi mizere yopyapyala yambiri yomwe imawoneka kuti ili pamwamba pa mawonekedwe owonekera - masipoko a njinga, ivy pamakoma a nyumba, ndi zina zotero. Madera awa a chimango amawoneka ngati DLSS sikuyesera kukulitsa kusamvana.

Kuphatikiza apo, pazithunzi zovuta kwambiri (mwachitsanzo, mkati mwa nkhalango), neural network nthawi zina imasokonekera ndikuyamba kusokoneza zinthu zomwe imachita momveka bwino (monga zovala ndi tsitsi la munthu wamkulu). Kamera ikamayenda kwambiri, zitsanzo zabodza zimawonekera pamadenga azitsulo (komabe, sizingatheke kuziwona zikuyenda). Pomaliza, DLSS imakulitsa kusiyanitsa konsekonse, mosasamala kanthu za zomwe zili mu chimango. Koma izi ndi kulakwitsa. Pazonse, Shadow of the Tomb Raider idapeza zotsatira zabwino kwambiri pamasewera anayiwa ndi chithandizo cha DLSS - timalimbikitsa mwamphamvu kuti izi zitheke, makamaka pa 2160p kuphatikiza ndi DXR.

Kuyesa magwiridwe antchito kunachitika pogwiritsa ntchito benchmark ya Shadow of the Tomb Raider yokhala ndi zosankha zonse zojambulira pamtengo wapamwamba (kupatula anti-aliasing ndi DXR, zomwe timasiyana pamayesero). Miyezo yapakati komanso yocheperako imachokera ku nthawi zowonetsera za mafelemu apawokha, zomwe masewerawa amalemba ku fayilo yazotsatira.
