Sony Patent Details PSSR 2.0 With Dynamic AI Precision to Stabilize PS5 Pro Frame Rates

A newly surfaced filing describes real-time precision scaling in the upscaler to hold performance without cutting native resolution, with release timing unannounced.

Overview

  • The patent outlines real-time monitoring of CPU and GPU load so the upscaler can temporarily lower neural-network precision to prevent frame drops without reducing a game's base resolution.
  • Sony specifies that reducing the accuracy of ANN inference via lower-precision weights or activations is acceptable to maintain smooth animation and perceived image quality.
  • The approach is framed as multi-frame super resolution that optimizes memory access and computation based on processing-unit usage during gameplay.
  • Reports say Sony has confirmed PSSR 2.0, though the company has not provided a release date and real-world effectiveness remains unproven.
  • Coverage notes ongoing PSSR updates since PS5 Pro’s launch, developer-reported inconsistencies in some titles, and reporting that Sony, led by Mark Cerny, is working with AMD on elements related to FSR4.
