Sony Launches QSSR AI Upscaling for Standard PS5, Debuting in Wolverine and Ghost of Yōtei

Key points

• Sony announced QSSR as a new performance tier of AI upscaling for the standard PS5 console.
• The technology is available now as a patch for Marvel's Wolverine and Ghost of Yōtei.
• QSSR is described as a streamlined version of the PS5 Pro's PSSR, utilizing a hand-tuned neural network architecture.
• The technology is the result of 'Project Amethyst,' a collaboration between Sony and AMD.
• Sony plans to offer QSSR broadly to all PlayStation developers in the future.

Background

The PS5 Pro launched with PlayStation Spectral Super Resolution (PSSR), which uses dedicated machine learning silicon to upscale images to 4K with high fidelity. The standard PS5 lacks this dedicated AI hardware, making the implementation of similar technology a significant technical challenge for Sony. Previous upscaling solutions on the PS5, such as AMD's FSR, have been standard but lacked the AI-driven detail refinement of PSSR.

How outlets are covering it

Eurogamer highlights that QSSR provides a 'taste' of the PS5 Pro experience, noting that Digital Foundry found the quality boost in Marvel's Wolverine to be 'exceptional' with improved temporal stability. However, Eurogamer points out a 'big divide' remains between QSSR on the standard PS5 and PSSR on the Pro. The Verge emphasizes the technical constraints, noting that because the PS5 lacks dedicated ML silicon, users should expect closer to upscaled 1440p rather than the 4K output of the Pro. Sony's official blog frames QSSR as a 'drop-in replacement' for titles already supporting PSSR, requiring only a few days of tuning, which suggests a low barrier to entry for developers.

Why it matters

This development bridges the gap between the standard and Pro versions of the PS5, offering standard console owners access to AI-enhanced visuals that were previously exclusive to the higher-end hardware. It also signals a shift in how Sony approaches hardware optimization, leveraging software solutions to mitigate hardware limitations. For developers, the ease of integration could lead to widespread adoption, potentially improving the visual fidelity of the entire PS5 library.

What to watch

Sony has stated that QSSR will be offered broadly to all PlayStation developers. The next step will be to monitor which other titles adopt the technology and how it performs across various game genres. Additionally, the impact of a recent PS5 firmware update on system stability may interact with the new upscaling features, though this is not yet confirmed.
