Using AMD and Nvidia GPUs Simultaneously: A Unique Experience

Witness the unthinkable: pairing an AMD and Nvidia GPU in the same system. While using both the AMD RX 6600 and Nvidia RTX 4090 concurrently seems daunting, the results have been surprisingly impressive, albeit with some limitations.

QuasarZone embarked on this “crazy idea,” pairing the Nvidia RTX 4090 with an RX 6600 to harness the combined power of Nvidia’s DLSS 3 and AMD’s Fluid Motion Frames (AFMF) – which is still in the technical preview stage.

The setup process of running both GPUs isn’t effortless. However, the results have led to a substantial boost in frames per second (fps) in demanding games like Cyberpunk 2077, Call of Duty: Modern Warfare III, Ratch & Clank: Rift Apart, and Starfield – despite the inherent challenges.

Remarkably, Cyberpunk 2077 saw a 291% increase in fps, achieving up to 209 fps with DLSS Frame Generation and AFMF both enabled. Although the experiment worked, it’s not a sustainable approach due to the potential for system instability.
