AMD Democratizes Next-Gen Upscaling by Porting FSR 4 to Legacy Radeon GPUs

By extending hardware-backed FSR 4 support to RDNA3 and RDNA2 architectures, AMD is significantly prolonging the lifespan of older consoles and handhelds like the Steam Deck. This strategic pivot ensures that AI-driven image quality improvements aren't locked behind the latest hardware, though the transition from FP8 to INT8 hardware may introduce performance trade-offs.
