NVIDIA RTX and DLSS come to ARM, big time

During the Games Developers Conference (GDC) the arrival of NVIDIA RTX and NVIDIA DLSS to ARM was confirmed, two technologies that, as our regular readers will know, have different objectives, but complement each other perfectly, since both offer very attractive values ​​when working in tandem.

NVIDIA RTX is an implementation of ray tracing that NVIDIA has applied to both games and professional applications, and it supports DirectX 12 and Vulkan. Through this technology, it is possible to apply highly realistic global lighting effects, reflections, refractions, shadows and ambient occlusion, although at the cost of a greater consumption of resources. To make this possible, NVIDIA uses the RT cores, which take care of the entire workload that ray tracing represents, and also adds DLSS technology.

DLSS is defined as a technique of intelligent image reconstruction which, in short, combines multiple images rendered at a lower resolution to create one high-quality image. This technology only chooses the best images, and uses motion vectors to achieve a more precise and better adjusted result than we would have with the game configured in native resolution. Therefore, it is not limited to rescaling with spatial elements, as the AMD FSR does.

The arrival of NVIDIA RTX and DLSS to ARM has marked a major turning point, as it means that GeForce RTX 30 series graphics cards can work seamlessly with processors based on that architecture. In this case, a SoC MediaTek Kompanio 1200, which is equipped with a eight cores divided from two blocks, one high performance and one high efficiency. The first uses the architecture ARM Cortex-A78, and the second the architecture ARM Cortex-A55.

Wolfenstein: Youngblood, the first PC game with NVIDIA RTX and DLSS that works on ARM

And it does it wonderfully, thanks to the fantastic optimization, and the enormous versatility, that the id Software idTech 6 graphics engine has. In the attached video we can see Wolfenstein: Youngblood working with NVDIA RTX and DLSS on an RTX 3060 and a MediaTek Kompanio 1200 chip, and we also have in the final part the Bistro demo, one of the most demanding in its category, which also works wonders in that setup.

Both demos have been executed in real time, and have been created thanks to the adaptation of various development kits that can now work with ARM-based devices and equipment. NVIDIA has confirmed to us, among others, the following:

Deep Learning Super Sampling (DLSS), which intelligently reconstructs the image to improve performance without reducing image sharpness or quality.
RTX Direct Illumination (RTXDI), which allows adding highly realistic dynamic lighting to any type of stage.
NVIDIA Optix AI-Acceleration Denoiser (NRD), which uses artificial intelligence to reduce noise generated in images by applying ray tracing.
RTX Memory Utility (RTXMU), which optimizes graphics memory management and consumption when using ray tracing.
RTX Global Illumination (RTXGI), which allows to generate highly realistic global lighting effects, with bounces and direct and indirect interactions.

The RTXDI, NRD and RTXMU Development Kits for ARM on Linux and Chromium are already available, and according to NVIDIA the RTXGI and DLSS kits will be available very soon.

We are facing a very important movement by NVIDIA, not only because of what this means for the gaming world, and for the growth of NVIDIA RTX and DLSS technologies, but also because of what it represents for other key sectors, such as the automotive industry, for example, where x86 chips have no place. It goes without saying that it is also a logical and meaningful step after NVIDIA’s purchase of ARM, an operation that still does not have the green light due to the doubts it raises regarding monopoly and competition, but that, in principle, should be able to arrive at a good port sooner or later.
