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.
