Kusukela namuhla, ukulandelela kwe-ray ngesikhathi sangempela akusekelwa kuphela amakhadi ehluzo e-GeForce RTX, kodwa futhi namakhadi ehluzo we-GeForce GTX 16xx kanye ne-10xx. Umshayeli we-GeForce Game Ready 425.31 WHQL, ohlinzeka ngamakhadi evidiyo ngalo msebenzi, usengakwazi ukudawuniloda kuwebhusayithi esemthethweni ye-NVIDIA noma abuyekezwe ngohlelo lokusebenza lwe-GeForce Now.
Uhlu lwamakhadi evidiyo asekela ukulandelela kwe-ray ngesikhathi sangempela luhlanganisa i-GeForce GTX 1660 Ti ne-GTX 1660, i-Titan Xp ne-Titan X (Pascal), i-GeForce GTX 1080 Ti ne-GTX 1080, i-GeForce GTX 1070 Ti ne-GTX 1070, kanye ne- I-GeForce GTX 1060 ene-6 GB yememori. Vele, ukulandelela ama-ray lapha kuzosebenza nokulinganiselwa okuthile uma kuqhathaniswa namakhadi wehluzo we-GeForce RTX. Futhi ikhadi levidiyo lincane, imikhawulo izoba namandla. Kodwa-ke, iqiniso lokuthi abanikazi be-GeForce GTX 1060 engenamandla kangako bazokwazi "ukuthinta" ubuchwepheshe obusha ngeke bajabule.
Ngenkathi amakhadi wevidiyo e-GeForce RTX enamayunithi ekhompiyutha akhethekile (ama-RT cores) ahlinzeka ngokusheshisa kwehadiwe ukulandelwa kwe-ray, amakhadi wevidiyo we-GeForce GTX awanazo izici ezinjalo. Ngakho-ke, ukulandelwa kwe-ray kusetshenziswa kuzo ngesandiso se-DXR se-Direct3D 12, futhi ukucutshungulwa kwe-ray kuzosingathwa ama-shader ajwayelekile okubalelwa kuxhaxha lwama-CUDA cores.
Le ndlela, vele, ngeke ivumele amakhadi wevidiyo asekelwe ku-Pascal nama-Turing GPU aphansi ukuthi anikeze izinga elifanayo lokusebenza kokulandela umsebe njengoba amamodeli ochungechunge lwe-GeForce RTX ekwazi ukwenza. Amaslayidi ashicilelwe i-NVIDIA anemiphumela yokuhlola ukusebenza kwamakhadi evidiyo ahlukahlukene kusetshenziswa ukulandela ngomsebe abonisa umehluko omkhulu phakathi kwamamodeli e-GeForce RTX kanye ne-GeForce GTX.
Isibonelo, emdlalweni we-Metro Exodus, lapho ukukhanya komhlaba wonke kunikezwa kusetshenziswa ukulandelela, alikho ikhadi levidiyo le-GeForce GTX elikwazi ukunikeza i-FPS eyamukelekayo. Ngisho nefulegi lesizukulwane sangaphambilini, i-GeForce GTX 1080 Ti, ikwazile ukukhombisa i-16,4 fps kuphela. Kodwa e-Battlefield V, lapho ukulandelela kunikeza kuphela ukucabangela, i-flagship yesizukulwane sikaPascal yakwazi ukufinyelela ku-30 ββFPS.
Kodwa-ke, i-NVIDIA ihlole amakhadi evidiyo kuzilungiselelo zezithombe eziphakeme kakhulu, ezinomthamo omkhulu wokulandela umsebe kanye nokulungiswa kwamaphikseli angu-2560 Γ 1440. Okusho ukuthi, izimo, ukuyibeka kahle, bekungeyona into evumayo kakhulu: iGeForce GTX 2060 efanayo kuMetro Eksodos ilinganiselwa ngaphezu kwamafps angama-34. Kuzokwazi ukuzuza i-FPS βedlalekayoβ kumakhadi wevidiyo amadala ngokwehlisa ukulungiswa kanye nekhwalithi yezithombe. Kodwa okokuqala, ukusebenza kwabo kuzothintwa izilungiselelo ze-ray tracing intensity.
Ake sikukhumbuze ukuthi okwamanje ungajwayelana nokulandelela ama-ray emidlalweni emithathu: I-Battlefield V, i-Metro Exodus kanye ne-Shadow of the Tomb Raider. Iyatholakala futhi ngamademo amathathu: Inhliziyo ye-Atomic, Justice and Reflections. Kokubili emidlalweni nakumademo ethulwa ngezinketho ezihlukahlukene zokusebenzisa ukulandelela ama-ray. Endaweni ethile inesibopho sokubonisa kanye nethunzi, futhi kwenye indawo inesibopho sokukhanya komhlaba.
