Sony has entered the machine-learning based image reconstruction competition with its PlayStation Spectral Super Resolution (PSSR), which is being compared to Nvidia’s DLSS and FSR 3.1. Digital Foundry recently had the opportunity to test PS5 Pro and Ratchet and Clank: Rift Apart to see how PSSR performs in comparison to the existing technologies.
It is essential to note the limitations of the comparison, as the exact quality settings cannot be matched between the PC and PS5 Pro versions of the game. Additionally, the dynamic resolution scaling used in Rift Apart makes the comparison challenging. However, the comparison provides valuable insights into the capabilities of PSSR in this specific game.
In the comparison, PSSR demonstrated impressive anti-aliasing capabilities, particularly in revealing new details. Unlike FSR 3.1, which struggles with anti-aliasing, PSSR maintains clarity in motion. Moreover, PSSR handles particles, hologrammatic signs, and grass textures more effectively than FSR 3.1. While it may not be perfect, PSSR shows promise in improving upscaling quality, especially at lower base resolutions.
When compared to DLSS, PSSR falls slightly short in anti-aliasing moving objects. However, it offers a softer image compared to DLSS, which some users may find preferable. PSSR also addresses issues with ray tracing ghosting, providing better stability in reflections. Despite these differences, further testing is required to provide a definitive verdict on PSSR’s overall performance.
Looking ahead, games like Alan Wake 2, with its demanding resolution requirements, will be crucial in determining PSSR’s true potential. As the PS5 Pro’s release date approaches, more comprehensive coverage of PSSR’s capabilities will be available. Stay tuned for additional insights into how PSSR compares to existing upscaling technologies and its impact on gaming experiences.
