At GDC final week, AMD shared some extra official particulars about FSR 3, the following technology of its upscaling expertise. FSR 3 continues to be in early growth, however AMD has some lofty objectives for the brand new model, together with a 2x body charge enchancment over FSR 2.
Stephan Hodes, a Core Technology Group engineer, began his presentation at GDC 2023 by speaking about FidelityFX Super Resolution applied sciences, with a specific emphasis on temporal upscaling. Starting with FSR 1 and shifting to FSR 2, he shared not simply the preliminary growth of those applied sciences but additionally talked about how FSR 2.1 and FSR 2.2 solved some points offered by the primary two implementations of the upscaling tech.
As AMD explains, FSR 2 computes extra pixels than we have now samples within the present body. However, it is potential to render much more pixes utilizing interpolated frames. That’s the place FSR 3 is available in, permitting the upcoming model of the pink group’s upscaling approach to double the framerate in some circumstances.
Still, some challenges need to be conquered to attain this. First, FSR 3 cannot depend on color clamping to regulate the color of outdated samples. Additionally, non-linear movement interpolation is advanced with 2D display screen house movement vectors, so AMD recommends an enter of no less than 60FPS. Lastly, if the ultimate frames are interpolated, the UI and any post-processing should even be. There’s a very good likelihood that each interpolated pixel could have no less than one pattern. Moreover, there isn’t any suggestions loop as a result of the interpolated body will solely be offered as soon as – any interpolation artefacts will solely be seen for one body.
Another level touched on through the presentation was latency. Moving from FSR to FSR 2, framerate features had been elevated whereas latency decreased. Applying body interpolation boosts framerate in addition to latency. As a consequence, FSR 3 will depend upon latency discount methods. Furthermore, FSR 3 will mix decision upscaling with body interpolation to make it simpler to implement FSR 3 on FSR 2 titles. In addition, to higher facilitate integration, FSR 3 is meant to be open-source like different FidelityFX applied sciences.
KitGuru says: Do you suppose FSR 3 will compete effectively up in opposition to DLSS 3?
