AMD’s software engineers provided some information on the upscaling technology update.
During the busy week of GDC 2023, AMD’s software engineering team presented a technical presentation on FidelityFX Super Resolution (FSR) 3.0, the latest version of their FidelityFX SDK. It goes without saying that the AI upscaling technology will replace the existing version, FSR 2.0, but more crucially, its parent company anticipates that the technology will replace NVIDIA’s own DLSS 3.0 upscaling technology.
In contrast to NVIDIA’s DLSS technology, which needs dedicated hardware and a GPU to function, such as its GeForce RTX Series graphics cards, AMD’s FSR technology is software-based and not entirely dependent on specialised hardware. More crucially, because every iteration of AMD’s upscaling technology has been open-source, practically every discrete graphics card may use it and gain the framerate bump it promises, and FSR 3.0 is no exception.
The functionality might essentially quadruple the framerate improvement already warranted by FSR 2.0, according to the software developers who worked on FSR 3.0. As a result, frame interpolation and resolution upscaling are combined to achieve this. Having said that, it seems that AMD still has some obstacles to overcome.
First off, it is still striving to reduce the whole delay produced by FSR, not only FSR 3.0. An immediate and perfect illustration of this can be found in NVIDIA’s current DLSS 3.0, which uses a new technology called Optical Flow Accelerator and Frame Generation to generate entirely new frames instead of pixels using the Tensor cores and RT cores in an RTX 40 Series GPU (the technology only works with Ada Lovelace cards). Although this approach produces a significant degree of latency, NVIDIA’s Reflex technology is automatically activated anytime DLSS 3.0 is active as a solution to the problem.
Based on the detail of one of its slides, it does seem that AMD is suffering from similar issues with FSR 3.0, and how it plans to overcome the issue is still up in the wind for now. Again, as mentioned earlier, the update will be open source and made available through an MIT license, so game developers and makers should be able to use and edit it, to the point that AMD should soon be able to release application samples and full documentation of its technology. At that point, too, games could then begin implementing the upscaling technology into their games as well.
