Here is the official list of graphics cards that support AMD FSR:
AMD Radeon 6000 series
AMD Radeon 6000M Series
AMD Radeon 5000 series
AMD Radeon 5000M. Series
AMD Radeon VII
AMD Radeon RX Vega Series
AMD Radeon 600. Series
AMD Radeon RX 500 series
AMD Radeon RX 480, 470 and 460
AMD Ryzen Desktop CPU with AMD Radeon Graphics
AMD Ryzen Mobile CPU with Radeon Graphics
Nvidia GeForce RTX 30 series
Nvidia GeForce RTX 20 series
