AMD’s competitor product to Nvidia’s DLSS 3 (Deep Learning Super Sampling) is ready: FidelityFX Super Resolution (FSR) in version 3 has artificial frame generation as its main feature to increase the frame rate in games. This is intended to enable the display of demanding titles in high resolution – particularly useful when ray tracing graphic effects are activated. In addition, FSR 3 brings a “Native AA” mode, which, similar to Nvidia’s DLAA, does not upscale the resolution, but rather smooths the edges at native resolution.

Artificial frame generation the manufacturer calls AMD Fluid Motion Frames (AFMF), where there are two versions. On the one hand, game developers can integrate AFMF into their titles, which has previously happened with the action role-playing game “Forspoken” and the first-person shooter “Immortals of Aveum”. This is how frame generation works best.
Driver variant without game integration
On the other hand, at least graphics cards from the Radeon RX 7000 series can also force AFMF on the driver side in DirectX 12 and DirectX 11 games. AMD provides a preview driver for this. For some titles such as “Starfield” and “Red Dead Redemption 2,” those interested simply need to activate HYPR-RX in the driver overview.
This is a collection of AMD technologies that, in addition to FSR3, also includes Radeon Boost and Radeon Anti-Lag. If desired, Radeon Boost dynamically lowers the resolution or shading rate (Variable Rate Shading, VRS) to increase the FPS. Radeon Anti-Lag removes the frame queue between the processor and graphics card to minimize input latency.
Anti-lag somewhat compensates for the increased latency caused by frame generation: current input data is missing in the artificial frames, which is therefore only adopted in every second image. AMD therefore recommends only activating AFMF at at least 60 real FPS.
In other games like “Cyberpunk 2077,” those interested must activate FSR 3 in the game-specific driver settings. An official game integration is to follow in “Cyberpunk 2077”.
The first planned games with FSR3 support. “Forspoken” and “Immortals of Aveum” have already received corresponding patches.

Without AI
Unlike Nvidia’s DLSS, AMD’s FSR does not use AI algorithms. The calculation is carried out exclusively using the game data to calculate multiple frames, for example using vector and geometry data. FSR 3 therefore also works on older graphics cards – AMD releases all models from the Radeon RX 5700 onwards. Nvidia’s GeForce graphics cards from the RTX 2000 series are also on board. The automatic driver only works with the Radeon RX 7000.
