A Crytek empresa revelou detalhes sobre sua recente demonstra\u00e7\u00e3o de ray tracing em tempo real com a pot\u00eancia da placa de v\u00eddeo Radeon RX Vega 56. Lembramos que, em meados de mar\u00e7o deste ano, o desenvolvedor publicou um v\u00eddeo mostrando o funcionamento do ray tracing em tempo real no motor CryEngine 5.5 usando uma placa de v\u00eddeo AMD.<\/p>\n

No momento da publica\u00e7\u00e3o do v\u00eddeo, a Crytek n\u00e3o revelou detalhes sobre o desempenho da Radeon RX Vega 56 na demonstra\u00e7\u00e3o Neon Noir. Agora, os desenvolvedores compartilharam detalhes: a placa de v\u00eddeo conseguiu garantir uma m\u00e9dia de 30 FPS na resolu\u00e7\u00e3o Full HD (1920 \u00d7 1080 pixels). Tamb\u00e9m foi observado que, se a qualidade\/intensidade da ilumina\u00e7\u00e3o global for reduzida pela metade, essa mesma placa gr\u00e1fica pode alcan\u00e7ar 40 FPS na resolu\u00e7\u00e3o QHD (2560 \u00d7 1440 pixels).<\/p>\n

\"A<\/p>\n

Na demonstra\u00e7\u00e3o Neon Noir, o ray tracing \u00e9 utilizado para criar reflexos e refra\u00e7\u00f5es de luz. Para ser justo, vale ressaltar que h\u00e1 realmente muitos reflexos, e a placa de v\u00eddeo Radeon RX Vega 56 conseguiu lidar com eles, mesmo sem a l\u00f3gica especializada para acelerar o ray tracing, como os n\u00facleos RT. Lembramos que, no momento, essa GPU da AMD se enquadra nas solu\u00e7\u00f5es de m\u00e9dio porte.<\/p>\n

O segredo do sucesso \u00e9 simples: o ray tracing na demonstra\u00e7\u00e3o da Crytek \u00e9 baseado em voxels. Essa abordagem requer significativamente menos poder computacional do que a tecnologia NVIDIA RTX. Gra\u00e7as a isso, placas de v\u00eddeo n\u00e3o apenas de top de linha, mas tamb\u00e9m de m\u00e9dio porte, podem construir imagens de qualidade utilizando ray tracing, independentemente de terem ou n\u00e3o l\u00f3gica especializada para essas tarefas.<\/p>\n

<\/center>
\n\"A<\/p>\n

Mas, ainda assim, a Crytek destaca que n\u00facleos RT especializados podem acelerar significativamente o ray tracing. E considerando que n\u00e3o existem obst\u00e1culos para o uso dessas tecnologias com a Crytek, j\u00e1 que as placas de v\u00eddeo GeForce RTX suportam o Microsoft DXR. Com a otimiza\u00e7\u00e3o correta, esses aceleradores poder\u00e3o garantir a m\u00e1xima qualidade de ray tracing na demonstra\u00e7\u00e3o Neon Noir, mesmo na resolu\u00e7\u00e3o 4K (3840 \u00d7 2160 pixels). Para compara\u00e7\u00e3o, a GeForce GTX 1080 possui um desempenho duas vezes inferior. Isso significa que a GeForce RTX n\u00e3o oferece novas possibilidades no motor CryEngine, mas sim melhor desempenho e detalhamento.<\/p>\n

\"A<\/p>\n

Ao final, os desenvolvedores da Crytek observaram que tamb\u00e9m h\u00e1 muitos benef\u00edcios para o uso de ray tracing em tempo real com APIs modernas como DirectX 12 e Vulkan. O fato \u00e9 que elas oferecem amplo acesso de baixo n\u00edvel ao , permitindo melhor otimiza\u00e7\u00e3o e utiliza\u00e7\u00e3o de todos os recursos para trabalhos pesados com ray tracing.<\/p>\n
