AMD FSR 2.0 has been added to the PC version of God of War with today's update v1.0.12, as revealed by developer Sony Santa Monica with a brief message.

God of War is only the third game to officially support AMD FSR 2.0, following Arkane's Deathloop and Giants Software's Farming Simulator 22, which added AMD FidelityFX Super Resolution 2.0 with a patch released last week.
