From PS5 to PC: AMD Reveals Sony's Role in Developing FSR 4

AMD has officially unveiled details of its collaboration with Sony Interactive Entertainment as part of Project Amethyst, confirming that the AI technologies developed in partnership with PlayStation form the foundation of the new FSR 4. This move not only strengthens the alliance between these industry giants but also opens a new chapter in the evolution of graphics technology for gaming platforms.

Project Amethyst, announced in 2023 as a joint initiative to integrate AI into gameplay and visualization, has now entered an active phase. Sony PlayStation engineers played a crucial role in training the neural network models that serve as the “brain” behind FSR 4. According to AMD, the integration of Project Amethyst’s solutions has achieved unprecedented accuracy in image reconstruction, particularly in dynamic scenes.

An analysis of the list of games supporting FSR 4 reveals an interesting trend: among the early-adopted projects are virtually all major Sony PC ports. God of War: Ragnarok, Horizon Forbidden West, and The Last of Us Part I are already showcasing the technology’s advantages, thanks to a flexible API inherited from FSR 3.1. This is no coincidence — Sony has purposefully laid the groundwork for the rapid rollout of future updates.

Experts are also drawing attention to the parallel development of two upscalers — FSR 4 for PC and PSSR, created by Sony for the PlayStation 5 Pro. Analysts suggest that the collaborative efforts under Project Amethyst could eventually lead to a convergence of these technologies. AMD hints that FSR 4 is just the first visible result of their alliance, with future plans including the development of tools for procedural texture generation, AI-driven physics optimization, and even dynamic gameplay adaptation tailored to individual player styles.

With the release of FSR 4 and the announcement of the Radeon RX 9070 graphics cards—the first to fully support the technology—AMD is strengthening its position in the battle against NVIDIA DLSS. However, the key question remains: will Project Amethyst serve as a bridge between console and PC ecosystems, or will the companies maintain their technological sovereignty? Discussions on this topic are already heating up on specialized forums.
