Older PlayStation 5 Games May Need a Later SDK for QSSR

Sony’s Quick Spectral Super Resolution (QSSR) is an AI-driven upscaling technology for PlayStation 5. It is similar to the PlayStation 5 Pro’s PSSR upscaler and can run on the base console, potentially narrowing the image quality gap between the two systems.

Retrofitting games for QSSR may require only tuning, according to Daniel Craig, Principal Engineer for Graphics R&D at SIE. But the process could still pose development challenges for older titles. The source report says those challenges could significantly limit how many older games support the upscaler.

One possible obstacle is the software development kit (SDK) used by a game. The report’s headline says some older games could need a later SDK, while the available source summary does not provide further details about that requirement. It also ends partway through a quotation attributed to Craig, so the full remark and its context are not available here.

As a result, the extent of QSSR support across older PlayStation 5 games remains uncertain. The source describes retrofits as easy to carry out with some tuning, while also pointing to potential development hurdles.
