Kutanga nhasi, chaiyo-nguva ray tracing inotsigirwa kwete chete neGeForce RTX makadhi emifananidzo, asiwo nekusarudza GeForce GTX 16xx uye 10xx makadhi emifananidzo. Iyo GeForce Game Ready 425.31 WHQL mutyairi, iyo inopa makadhi evhidhiyo ane basa iri, inogona kutotorwa kubva kune yepamutemo NVIDIA webhusaiti kana kuvandudzwa kuburikidza neGeForce Zvino application.
Rondedzero yemakadhi evhidhiyo anotsigira chaiyo-nguva ray tracing inosanganisira iyo GeForce GTX 1660 Ti uye GTX 1660, Titan Xp uye Titan X (Pascal), GeForce GTX 1080 Ti uye GTX 1080, GeForce GTX 1070 Ti uye GTX 1070, pamwe neiyo GeForce GTX vhezheni 1060 ine 6 GB yekuyeuka. Ehe, ray yekutevera pano ichashanda nezvimwe zvisingakwanisi zvichienzaniswa neGeForce RTX makadhi emifananidzo. Uye muduku kadhi yevhidhiyo, iyo yakasimba zvirambidzo zvichave. Nekudaro, chokwadi chekuti varidzi veiyo-isina-simba-iyo GeForce GTX 1060 vachakwanisa "kubata" tekinoroji nyowani haigone asi kufara.
Nepo GeForce RTX makadhi evhidhiyo ane nyanzvi dzemakomputa zvikamu (RT cores) inopa hardware kukwidziridzwa kweray tracing, GeForce GTX makadhi evhidhiyo anongove asina zvinhu zvakadaro. Naizvozvo, ray tracing inoitwa mavari kuburikidza neiyo DXR yekuwedzera yeDirect3D 12, uye ray process ichabatwa neyakajairwa computational shader pane akatevedzana eCUDA cores.
Iyi nzira, hongu, haizotenderi makadhi evhidhiyo akavakirwa paPascal uye akadzika Turing GPUs kuti ape iyo yakafanana nhanho yekutevera ray kuita senge GeForce RTX akatevedzana modhi anokwanisa. Masiraidhi akaburitswa neNVIDIA nemhedzisiro yekuyedza kuita kweakasiyana makadhi evhidhiyo uchishandisa ray tracing inoratidza musiyano mukuru pakati peGeForce RTX neGeForce GTX modhi.
Semuenzaniso, mumutambo weMetro Exodus, uko kuvhenekerwa kwepasirese kunopihwa uchishandisa kutsvaga, hapana yemakadhi evhidhiyo eGeForce GTX akakwanisa kupa FPS inogamuchirwa. Kunyangwe iyo mureza wechizvarwa chakapfuura, GeForce GTX 1080 Ti, yakangokwanisa kuratidza 16,4 fps. Asi muBattlefield V, uko kutsvaga kunongopa zviratidziro, mureza wechizvarwa chePascal wainge uchiri kukwanisa kusvika makumi matatu FPS.
Nekudaro, NVIDIA yakaedza makadhi evhidhiyo panzvimbo yepamusoro yemifananidzo, ine yakanyanya ray yekutevera kusimba uye pakugadziriswa kwe2560 Γ 1440 pixels. Ndiko kuti, mamiriro, kuisa zvinyoro, anga asiri iwo akanyanya kunaka: yakafanana GeForce GTX 2060 muMetro Exodus yakaenzana zvishoma kupfuura 34 fps. Izvo zvinogoneka kuwana "inotamba" FPS pamakadhi evhidhiyo ekare nekudzikisira kugadzirisa uye mifananidzo yemhando. Asi chekutanga pane zvese, kuita kwavo kuchakanganiswa neiyo ray tracing intensity marongero.
Ngatikuyeuchidzei kuti panguva ino iwe unogona kujairana neray tracing mumitambo mitatu: Battlefield V, Metro Exodus uye Shadow yeTomb Raider. Inowanikwawo mumademo matatu: Atomic Heart, Justice uye Reflections. Zvese mumitambo uye mumademo tinounzwa nemhando dzakasiyana dzekushandisa ray tracing. Pane imwe nzvimbo ine basa rekuratidzira uye mimvuri, uye kumwe kunhu kune basa rekuvhenekera kwepasirese.
