PlayStation 5's PSSR 2.0 uses AMD's FSR 4's INT8 version that may skip PC RDNA 2 & 3 GPUs

[Redaktion]

A leaked AMD GitHub repository revealed an INT8 build of FSR 4 that appears capable of running on RDNA 2 and RDNA 3 GPUs, even as AMD positions official FSR 4 support exclusively for newer RDNA 4 hardware. Sony has effectively deployed this same INT8 technology as the PlayStation 5's upgraded PSSR (often dubbed PSSR 2.0), prompting modders to port the leaked libraries to Radeon RX 6000 and 7000 cards while AMD remains publicly silent.
