Sony Interactive Entertainment deployed PlayStation Spectral Super Resolution (PSSR), an AI-powered image upscaling system, on the PlayStation 5 Pro console that analyzes game images pixel by pixel to render them at higher visual quality than the base resolution.

PSSR is described by Sony as 'an AI library that analyzes game images pixel by pixel as it upscales them.' As of February 2026, PSSR had been used to boost the effective resolution of over 50 PS5 Pro titles. An upgraded version of PSSR, developed in collaboration with AMD under 'Project Amethyst,' was rolled out via system software update in March 2026, with improvements to image reconstruction precision, motion stability, and developer flexibility. The new PSSR algorithm and neural network are co-developed with AMD's FSR 4 upscaling technology. The system is available to all PS5 Pro users via console settings, and game developers can opt into PSSR support through patches.
