In a new video, leaker Moore's Law is Dead has sources that have explained to him that PSSR is Sony's new Multi-Frame Super Resolution (MSFR) implementation. It uses PlayStation Machine learning (PSML) to perform super-resolution processing on input data to generate color buffers with a current maximum resolution of 4K, although support for resolutions up to 8K are coming in a future version of the SDK.

PSSR is a machine learning-enhanced version of Temporal Anti-Aliasing Upscal (TAAU). It will replace a game's existing temporal anti-aliasing or temporal upsampling. The inputs are "quite similar to DLSS or FSR" with full HDR support.

There's no per-title training needed for the dynamic input resolution, with PSSR using around 250MB of memory (some of which is from the library, some from the game). It only takes around 2ms for upscaling 1080p to 4K, with "optimization ongoing, may see a reduction in running time in future."

Well, there we have it... PSSR is a pretty damn big game change for Sony and it's upcoming PlayStation 5 Pro console, which will be the absolute console of choice for Grand Theft Auto 6 when it drops next year.
