Crytek tau tshaj tawm cov ntsiab lus hais txog nws qhov kev ua yeeb yam tsis ntev los no ntawm lub sijhawm tiag tiag ntawm txoj kab hluav taws xob ntawm lub zog ntawm Radeon RX Vega 56 daim npav video. tracing khiav ntawm CryEngine 5.5 cav siv ib daim npav AMD.
Thaum lub sijhawm tshaj tawm cov yeeb yaj kiab nws tus kheej, Crytek tsis tau tshaj tawm cov ntsiab lus hais txog qib kev ua haujlwm ntawm Radeon RX Vega 56 hauv Neon Noir demo. Tam sim no cov neeg tsim khoom tau qhia cov ntsiab lus: daim npav video tau muab qhov nruab nrab ntawm 30 FPS hauv Full HD daws teeb meem (1920 Γ 1080 pixels). Nws kuj tseem tau sau tseg tias yog tias qhov zoo / kev siv ntawm cov kab hluav taws xob tracing yog ib nrab, ces tib cov duab accelerator tuaj yeem muab 40 FPS hauv QHD daws teeb meem (2560 Γ 1440 pixels).
Hauv Neon Noir demo, ray tracing yog siv los tsim kev cuam tshuam thiab kev cuam tshuam ntawm lub teeb. Yuav kom ncaj ncees, nws tsim nyog sau cia tias muaj ntau qhov kev xav ntawm no, thiab Radeon RX Vega 56 daim npav video muaj peev xwm tiv nrog lawv, txawm tias tsis muaj qhov tshwj xeeb logic kom nrawm nrawm zoo li RT cores. Cia peb nco ntsoov koj tias tam sim no AMD daim npav video koom nrog cov kev daws teeb meem ntawm ntu nruab nrab nqi.
Cov lus zais rau kev vam meej yog qhov yooj yim: txoj kab hluav taws xob tracing hauv Crytek's demo yog voxel-based. Txoj hauv kev no yuav tsum muaj lub zog suav tsawg dua li NVIDIA RTX thev naus laus zis. Vim qhov no, tsis yog tsuas yog high-end, tab sis kuj yog cov nqi nruab nrab ntu video phaib tuaj yeem tsim cov duab zoo siv cov duab hluav taws xob, tsis hais seb lawv puas muaj kev tshwj xeeb rau cov haujlwm zoo li no lossis tsis.
Tseem, Crytek sau tseg tias tshwj xeeb RT cores tuaj yeem ua kom nrawm nrawm dua. Ntxiv mus, tsis muaj teeb meem rau lawv siv nrog Crytek technologies, vim GeForce RTX video phaib txhawb Microsoft DXR. Nrog rau kev ua kom zoo, cov accelerators no yuav muaj peev xwm muab qhov zoo tshaj plaws tracing zoo nyob rau hauv Neon Noir demo, txawm nyob rau hauv 4K daws teeb meem (3840 Γ 2160 pixels). Rau kev sib piv, GeForce GTX 1080 muaj ib nrab ntawm kev ua haujlwm. Nws hloov tawm tias GeForce RTX tsis muab cov yam ntxwv tshiab hauv CryEngine lub cav, tab sis nws muab kev ua tau zoo dua thiab nthuav dav.
Thiab thaum kawg, Crytek cov neeg tsim khoom tau sau tseg tias APIs niaj hnub zoo li DirectX 12 thiab Vulkan kuj muab ntau yam zoo rau kev siv cov duab hluav taws xob hauv lub sijhawm. Qhov tshaj plaws yog tias lawv muab kev nkag mus rau qib qis rau cov khoom siv dav dav, vim tias qhov kev ua kom zoo dua qub tuaj yeem ua tau thiab siv tag nrho cov peev txheej rau kev ua haujlwm hnyav nrog txoj kab hluav taws xob tracing yog ua tau.
