Sony Unveils QSSR AI Upscaler for the Base PS5

The PSSR upscaler has been available to PS5 Pro users for some time, and now Sony has announced a new version designed specifically for the base PS5 — Quick Spectral Super Resolution (QSSR).

QSSR was developed as part of Project Amethyst, a joint project between Sony and AMD. The technology uses a lightweight neural network architecture and algorithms optimized for the base console, allowing it to efficiently reconstruct an image from a low source resolution while delivering high detail and excellent temporal stability between frames.

The new technology is not positioned as a full replacement for PSSR, which Sony still calls the gold standard for PS5 Pro. Due to the difference in hardware, the systems have different key goals: while the Pro version is designed for 4K output, 1440p remains the optimal target resolution for the base console. Nevertheless, Sony promises gamers a major leap in the clarity of small objects and scene stability compared with the traditional spatial scaling methods previously used on the platform.

QSSR can already be seen in action: the technology officially debuted in Marvel’s Wolverine and Ghost of Yōtei. Third-party studios have also received full access to the toolset. Although QSSR’s peak computing performance is noticeably lower than that of PSSR on PS5 Pro, the new upscaler gives developers much more flexibility when optimizing titles. Sony also emphasizes that integrating QSSR into games has been made as straightforward as possible and will not require a major time investment from game studios.
