Kuyambira lero, kufufuza kwa ray kwa nthawi yeniyeni sikuthandizidwa ndi makadi ojambula a GeForce RTX okha, komanso ndi makadi ojambula a GeForce GTX 16xx ndi 10xx. Dalaivala wa GeForce Game Ready 425.31 WHQL, yemwe amapereka makadi a kanema ndi ntchitoyi, akhoza kutsitsa kale patsamba la NVIDIA kapena kusinthidwa kudzera mu pulogalamu ya GeForce Tsopano.
Mndandanda wa makadi amakanema omwe amathandizira kufufuza kwa ray mu nthawi yeniyeni akuphatikizapo GeForce GTX 1660 Ti ndi GTX 1660, Titan Xp ndi Titan X (Pascal), GeForce GTX 1080 Ti ndi GTX 1080, GeForce GTX 1070 Ti ndi GTX 1070, komanso GeForce GTX 1060 yokhala ndi 6 GB ya kukumbukira. Zachidziwikire, kutsata ma ray apa kudzagwira ntchito ndi malire poyerekeza ndi makadi ojambula a GeForce RTX. Ndipo aang'ono khadi la kanema, zoletsazo zidzakhala zamphamvu. Komabe, kuti eni ake a GeForce GTX 1060 omwe alibe mphamvu kwambiri adzatha "kukhudza" teknoloji yatsopano sangasangalale.
Ngakhale makhadi amakanema a GeForce RTX ali ndi mayunitsi apadera apakompyuta (RT cores) omwe amapereka mathamangitsidwe a hardware pakutsata ray, makhadi a kanema a GeForce GTX alibe zinthu zotere. Chifukwa chake, kutsata ma ray kumayendetsedwa mwa iwo kudzera pakukulitsa kwa DXR kwa Direct3D 12, ndipo kukonza kwa ray kudzayendetsedwa ndi ma shader wamba pamitundu yambiri ya CUDA cores.
Njira iyi, inde, singalole makhadi a kanema ozikidwa pa Pascal ndi ma GPU otsika a Turing kuti apereke mulingo womwewo wa ray tracing performance monga mitundu ya GeForce RTX ingatheke. Makanema ofalitsidwa ndi NVIDIA okhala ndi zotsatira zoyesa magwiridwe antchito a makadi osiyanasiyana amakanema pogwiritsa ntchito ray tracing akuwonetsa kusiyana kwakukulu pakati pa mitundu ya GeForce RTX ndi GeForce GTX.
Mwachitsanzo, mu masewero a Metro Eksodo, kumene kuunikira kwapadziko lonse kumaperekedwa pogwiritsa ntchito kufufuza, palibe makhadi a kanema a GeForce GTX omwe anatha kupereka FPS yovomerezeka. Ngakhale mbendera yam'badwo wam'mbuyomu, GeForce GTX 1080 Ti, idangowonetsa 16,4 fps. Koma mu Nkhondo ya V, komwe kutsata kumangowonetsa zowunikira, mbiri ya m'badwo wa Pascal idakwanitsa kufikira 30 FPS.
Komabe, NVIDIA idayesa makadi amakanema pamalo owoneka bwino kwambiri, okhala ndi kuchulukira kwa ray komanso pakutha kwa ma pixel a 2560 Γ 1440. Ndiko kuti, mikhalidwe, kunena mofatsa, sizinali zabwino kwambiri: GeForce GTX 2060 yomweyo mu Metro Exodus inali yoposa 34 fps. Zikhala zotheka kukwaniritsa FPS "yoseweredwa" pamakhadi akale akanema pochepetsa kusamvana ndi mawonekedwe azithunzi. Koma choyamba, machitidwe awo adzakhudzidwa ndi makonda a ray tracing intensity.
Tikukumbutseni kuti pakadali pano mutha kudziwana ndi kufufuza kwa ray mumasewera atatu: Nkhondo V, Metro Eksodo ndi Shadow of the Tomb Raider. Imapezekanso m'ma demos atatu: Atomic Heart, Justice ndi Reflections. M'masewera ndi ma demo timapatsidwa zosankha zingapo zogwiritsira ntchito kufufuza kwa ray. Kwinakwake imakhala ndi udindo wowunikira ndi mithunzi, ndipo kwinakwake imayang'anira kuunikira kwapadziko lonse lapansi.
