PS5 Pro's PSSR upscaler tested against FSR 3.1 and Nvidia DLSS 3.7 in Ratchet and Clank: Rift Apart

Sony's PS5 Pro PSSR vs FSR 3.1 vs DLSS 3.7. Digital Foundry puts Sony's upscaler through its paces.

With PlayStation Spectral Super Resolution (PSSR), Sony has joined the machine-learning based image reconstruction race started by Nvidia almost six years ago. If we consider that this is the first publicly seen iteration of PSSR, we can safely assume that it manages to do the job required of it - it offers a substantial upgrade to upscaling quality, but do bear in mind we're still dealing with relatively high base resolutions. But perhaps it's games like Alan Wake 2 that will best prove its worth: an internal 864p in its 60fps performance mode, upscaled to full 4K is a daunting task for the tech - and we're looking forward to testing this, along with other titles that have perhaps pushed FSR technology too far on the standard PS5 and Xbox consoles.
