The RTX On real-time ray tracing and DLSS technologies promoted by NVIDIA since the GeForce RTX 20 series of Turing architecture have gradually blossomed. The light and shadow effects brought by the RTX On real-time ray tracing further make the game vision and scene interaction more realistic, and based on AI DLSS technology enables GPU to take into account image quality and smoothness under the same hardware resources. The two complement each other and have been supported by many developers and game engines in the PC industry. This summer, there are also many new and old games that will be supported at the same time. RTX light chase and DLSS image enhancement technology, including the puzzle game LEGO Builder’s Journey, which will be released on June 22, as a representative, and Doom: Eternal/DOOM Eternal, Rust and other games will also Welcome DLSS technology blessing to further enhance the fluency of the game.
▲ The DLSS model is based on the FullHD resolution enhanced to 4K and compared with the native 16K image
Let’s first review the principle of DLSS technology. DLSS is an AI-accelerated image processing technology. The Tensor Core in the two architectures of NVIDIA Turing and NVIDIA Ampere is used for AI processing, so that the system does not need to diversify additional resources for AI acceleration. After lower resolution output, the resolution can be improved by DLSS technology, and the image quality is not inferior or even surpassed by native resolution rendering. At the same time, after enabling DLSS, the same system can achieve higher native resolution smoothness degree.
▲ Compared with native resolution and traditional upscaling technology, DLSS has the advantages of high efficiency and high image quality.
DLSS is an AI-based super-resolution algorithm that uses AI to process lower-resolution content into higher resolution. For example, the content of FullHD resolution is enhanced to 4K level, but unlike typical upscaling technology, DLSS uses The AI method of processing can present image quality that is no less than or even higher than the native resolution; as the basis of DLSS technology is the technology based on convolutional neural network autoencoder (convolutional autoencoder), which is advanced by NVIDIA supercomputers. Generate ultra-high-resolution native game screens as a comparison sample, allowing AI to learn how to enhance FullHD to 4K and compare the image quality with native 16K. Because the content of AI model training is to compare the output 4K image quality with 16K image quality By comparison, the details of the 4K image processed by DLSS are even better than that of the native 4K.
▲In-depth cooperation with game developers and game engine manufacturers has enabled RTX and DLSS to be rapidly popularized
▲Currently many popular games have or will join DLSS technology
The key to the rapid adoption of RTX Optical Chase and DLSS technology in the game industry is not only the charm of the technology itself, but also based on the cooperation with game developers and game engines. In addition to many large game developers, RTX Optical Chase and DLSS have been added. Independent game engine, currently supported by the two major third-party game engine developers; Epic has integrated technologies including ray tracing and NVIDIA DLSS into Unreal Engine 4, and the new generation of Unreal Engine 5 has been launched in May. Early access version. At present, developers can also add NVIDIA DLSS technology to the content through Plug In; as for another well-known commercial engine, Unity has also announced support for NVIDIA DLSS technology. The PC version of Lego will be launched on June 22. Journey will be the first Unity game with real-time ray tracing; in addition to the Windows PC platform, Linux system players will also be able to enjoy DLSS technology in Proton, a Windows emulator environment that supports Vulkan API games from June 22, and It is expected to provide support for DLSS of DirectX API environment within this year.
▲The effect after turning on ray tracing is closer to the real world
LEGO Builder’s Journey is a puzzle-solving game first launched by Apple Arcade. It uses the characteristics of Lego blocks as the props for the game to pass the level. Under the beautiful music, think about how to use the blocks provided by the level to break through the level, but the PC version In addition to improving the resolution, it also further enhances the material details, physical effects, etc., and the PC version’s ray tracing effects include shadows, reflections, ambient light occlusion and overall light, so that the light in the environment shines on different shapes of Lego bricks more realistic This is also the first Unity engine game to introduce ray tracing, and the hardware burden brought by ray tracing will also affect the smoothness of the game to some extent, which can make the game have a smoother experience after turning on DLSS.
In addition, from June, there will be a number of works that will receive DLSS technology through updates, such as Doom: Eternity, a first-person action shooter game that will simultaneously provide ray tracing and DLSS through the update on June 29 to further improve the screen. To a new level, but through DLSS, you can maintain the same or even higher fluency as before the upgrade of ray tracing. In addition, Rust, launched by Facepunch Studios, will support NVIDIA Reflex technology in May. It will also be upgraded to add DLSS technology on July 1. In addition to these games that will receive ray tracing or DLSS technology in the near future, Jade Blood 2 also announced that it will use Upgrade to join DLSS technology.
