Artificial frame generation technology. Even typing those words feels vaguely science-fiction, but ever since the release of Nvidia’s DLSS 3 Frame Generation (and much later, AMD’s Fluid Motion Frames), it’s become a concept that’s gone beyond the theoretical into the everyday. However, Korean technology website QuasarZone (via Videocardz) has taken things to a new extreme by managing to run both methods at the same time via an impressive bit of GPU wrangling, and the performance gains are, on the surface at least, rather impressive.

To achieve this mind-bending result, both an RTX 4090 and Radeon RX 6600 were installed on the same motherboard, with the monitor connected to the AMD GPU. The RTX 4090 was then forced to render a game with DLSS 3 Frame Generation enabled, while the RX 6600 was used as an output source to the monitor using AMD Fluid Motion Frames. This means the eventual output was rendered at a higher frame rate using DLSS 3 Frame Generation, then interpolated on…
