The design of the PlayStation 5 Pro was finalized prior to AMD's transition of FSR to a machine learning model, which means it does not support FP8 computations necessary for the complete version of FSR 4.

This oversight in the development timeline has created a fundamental compatibility gap that could negatively impact both performance and image quality.

Insider reports suggest that the PS5 Pro will need a custom version of the FSR 4 model, as it lacks critical features like FP8 support that are available in RDNA 4 GPUs.

Despite these challenges, the PS5 Pro is expected to deliver enhancements that improve the gaming experience compared to the standard PS5, although the effectiveness of the Spectral Super Resolution upscaler has varied across different games.

To fully utilize the AI-powered FSR 4, developers will likely need to update their games, since the current PlayStation Spectral Super Resolution upscaler does not support system-level DLL swaps.

Consequently, existing games that employ PlayStation Spectral Super Resolution (PSSR) will not automatically support AMD FSR 4, necessitating developer patches for current titles and specific integration for new releases.

AMD FSR 4 is projected to be available for the PlayStation 5 Pro in 2026, but existing games will require updates to take advantage of this new functionality.

The anticipated release of AMD FSR 4 for the PS5 Pro is set for 2026, which raises expectations for enhanced gaming experiences.

However, the implementation of FSR 4 on the PS5 Pro is expected to be complex, requiring careful optimization rather than straightforward updates, potentially resulting in significant differences compared to the PC version.
