What Nvidia has been working on for years and what is now working satisfactorily, should also be able to use Radeon graphics cards in the future: AI upscaling, which makes the game appear more detailed and sharper than the native render resolution would allow. This saves computing power and increases the frame rate.

AMD is developing its “Super Resolution” process together with Microsoft on the basis of the DirectX API DirectML ( Machine learning). It should ensure stable frame rates, especially when using performance-hungry ray tracing graphics effects. For the presentation of the Radeon RX graphics card series 2019, however, the function is not yet available. Open source and cross-platform Compared to media like Anandtech AMD explained that Super Resolution as part of the GPUOpen project should be open source and work across platforms. In the future, the chip manufacturer intends to offer developer tools for game studios within its own FidelityFX repertoire.

DirectML uses neural networks, for example, to enhance image quality. This works either via compute shaders or via special hardware cores. Microsoft has been experimenting with AI upscaling, also with the help of Nvidia, for at least a year and a half – in a GDC presentation from March 2019 one employee already called the function Super Resolution.

Upscaling with neural network Nvidia uses the technology a self-trained neural network that is fed with K-pictures of all kinds and based on the results learns to upscale lower-resolution moving pictures . Since Deep Learning Super Sampling (DLSS) 2.0, this has worked quite well. Game developers, however, have to incorporate the feature into their titles themselves.

In a blog post, Microsoft explains that the combined processors in the Xbox Series X and Xbox Series S already have hardware cores to accelerate DirectML algorithms and thus go beyond the capabilities of AMD’s “Big Navi” GPUs. Sony is apparently cooking its own soup, as the patents submitted for its own AI upscaling reveal.
