PSSR Upgrade Hits PS5 Pro in Weeks

🔑 Enhanced Key Takeaways

• •Improved PSSR is based on AMD’s FSR4 technology, co-developed through Sony and AMD’s Project Amethyst initiative, bringing six months of additional refinement tailored for PS5 Pro.[1][3]
• •Digital Foundry analysis praises the new PSSR in Resident Evil Requiem as 'the real deal,' addressing prior issues where original PSSR made some games look worse than on base PS5.[1]
• •A system software update in March 2026 will add a toggle to enable 'Enhance PSSR Image Quality' for existing PSSR-supported games, with multiple titles upgrading then.[1][3]

🛠️ Technical Deep Dive

• •New PSSR uses a different neural network and overall algorithm, stemming from Project Amethyst with AMD FSR4, analyzing game images pixel-by-pixel for upscaling.[1][3]
• •Sony patent for PSSR 2.0 (filed July 2025) describes multi-frame super resolution (MFSR) using a trained artificial neural network (ANN) to monitor processing unit load.[5]
• •During high loads, MFSR reduces AI upscaler precision dynamically to optimize memory access and computation, preventing frame rate drops without compromising resolution.[5]
• •Enables higher frame rates and resolutions by smoothing performance instead of dropping native resolution, reducing visual artifacts in complex scenes.[4][5]
