Idan aka yi la'akari da cewa wani yanki mai kyau na kasadar Lara Croft yana faruwa a ƙarƙashin ƙasa, Shadow of the Tomb Raider yana ƙunshe da wurare masu kama da juna. Ba tare da DXR ba, injin yana amfani da taswirar inuwa mai ƙarfi don yin tasirin hasken kai tsaye. Wannan hanya ta ɗan yi kama da ganowa a cikin taswirorin inuwa ana ƙirƙira su ta hanyar zayyana wurin daban daga mahangar da ta zo daidai da tushen hasken, amma tana da rashin amfani.

Ingancin Hoto: DLSS vs TAA

Binciken Ray, ko da a cikin ƙayyadadden tsari, kamar yadda aka yi a cikin Shadow of the Tomb Raider, yana shafar aikin GPU sosai, kuma wannan ya riga ya zama babban aiki mai matuƙar buƙata a saitunan ingancin hoto. Don rama abin da ba makawa ya kai ga ƙima, masu haɓaka wasan sun gabatar da tallafin DLSS a lokaci guda da DXR. Mun riga mun rubuta fiye da sau ɗaya game da fasahar mallakar mallakar ta NVIDIA, wanda ke ba GPU damar yin aiki a cikin ƙaramin ƙuduri sannan kuma auna firam ɗin ta amfani da hanyar sadarwa ta jijiyoyi akan jigon tensor na gine-ginen Turing. Koyaya, ƙwarewar aikin da Battlefield V, Final Fantasy XV da Metro Exodus suka bayar sun riga sun lalata duk wani hasashe game da ingancin DLSS a matakin farko na rarraba ta. Daga cikin wasannin majagaba guda uku, Final Fantasy XV ne kawai ke da fitowar DLSS mai kwatankwacin yin nuni kai tsaye a ƙudurin manufa, har ma tare da fa'idodi da yawa.

Ba lallai ba ne a faɗi, ba mu yi tsammanin kyakkyawan sakamako daga DLSS a cikin Inuwar Tomb Raider ba? Duk da haka, wasan ya ba mu mamaki mai dadi.
