The PS5 Pro PSSR 2 update is set to bring massive improvements to image quality and reduce performance overhead, based on a new rumor.
In his latest video, content creator and hardware insider Moore’s Law Is Dead (MLID) revealed that Sony Interactive Entertainment is preparing massive improvements for its PlayStation Spectral Super Resolution technology. He claimed that the upcoming PSSR 2 update for the PS5 Pro is not a minor iterative patch but a full-scale overhaul designed to dramatically improve upscaling quality, stability, and performance. According to a developer he spoke to, “It’s not some ‘0.5’ upgrade, it’s huge.”
The aforementioned developer provided new details on the development of PSSR and the tools now available to studios. One of the most noteworthy additions is a debug application called PSML Replay, which the console maker has reportedly distributed to developers to aid them in identifying and fixing artifacting issues caused by PSSR in existing games. The developer explained, “There is an application called PSML Replay that Sony has given us for debugging glitches that pop up from PSSR. So, Sony is aware that there are multiple big releases that have PSSR artifacting issues, and they are working on it. In fact, by now Sony has more tools for PSSR than AMD does for FSR 3 or FSR 4.”
Behind the scenes, PSSR is referred to internally as Multi-Frame Super Resolution, or MFSR, and the developer says references to “MFSR2” or “Multi-Frame Super Resolution 2” are now appearing in official developer documentation. They stated, “MFSR2 apparently uses an updated algorithm that reduces the need for some pieces of input data, decreases the amount of memory used, and shortens GPU processing times while delivering (allegedly) better image quality. It uses an entirely new API too. This is not some ‘0.5’ upgrade, it’s huge.”
The mention of a new API indicates that developers will need to update their games manually, and that this will not simply be a system-level toggle. MLID compares the scale of the upgrade to the generational jump from AMD’s FSR3 to FSR4.
The developer also noted that Sony Interactive Entertainment continues to treat PSSR as its own independent technology, separate from FSR. While the PS5 Pro is expected to support FSR4 next year, MLID was told that the console maker “want[s] to match or beat FSR4” with its own technology and has no intention of abandoning it in future hardware generations.
