AMD recently announced that its new FidelityFX Super Resolution 2.0 technology will be integrated into Xbox Series S/X consoles, along with all Radeon graphics cards on PC. For reference, this is an equivalent to the nVidia signed DLSS process.

As a reminder, DLSS (for Deep Learning Super Sampling) technology takes advantage of artificial intelligence algorithms to improve the sharpness of an image as if it had originally been drawn in the displayed resolution (when in fact, no). Concretely, the Xbox Series X should be able to run games at 60 frames per second in 4K relatively easily, instead of the lower definitions today, necessary to access this refresh rate.
Note that we do not yet know if FidelityFX Super Resolution 2.0 will arrive on PlayStation 5.
