According to the final system requirements for the PC version of the game, Cyberpunk 2077 will only launch with ray tracing support for NVIDIA GeForce RTX video cards. Although the AMD Radeon RX 6000 lineup also comes with this capability, it looks like Cyberpunk 2077 will add support for it in a future update.
