Using NVIDIA Frame Generation and AMD Fluid Motion Frames together

Using NVIDIA Frame Generation and AMD Fluid Motion Frames together improves performance by three times, but not without compromises

The Frame Generation feature for generating frames in games, part of NVIDIA’s DLSS 3 technology, and its counterpart Fluid Motion Frames (AFMF) from AMD can work together simultaneously in the games in which they are supported. Reports South Korean publication QuasarZone. However, this requires a number of compromises.

The NVIDIA Frame Generation (FG) and AMD Fluid Motion Frames (AFMF) technologies pursue the same goal: they create additional artificial frames in the game to improve smooth gameplay. Although video interpolation (frame generation) technology has been used in various contexts for many years, its implementation in games is more difficult due to the dynamic nature of real-time content generation.

NVIDIA Frame Generation (FG) technology is part of overall NVIDIA DLSS 3 technology and is only supported on GeForce RTX 40 series graphics cards. AMD Fluid Motion Frames, in turn, are part of FSR 3 (Next Generation Image Scaling) technology. AMD is also working on integrating AFMF as a separate HYPR-RX function into the graphics card driver. In any case, this also requires the use of branded Radeon graphics cards and the corresponding graphics driver.

The South Korean resource QuasarZone decided to check whether it is possible to use NVIDIA Frame Generation and AMD Fluid Motion frames simultaneously in games where both technologies are supported. To implement this idea in a PC, you need to use two graphics cards – from NVIDIA and AMD. This means that both graphics accelerators in the system will generate frames, which should theoretically lead to even greater performance improvements. Looking forward, we see that while using NVIDIA Frame Generation and AMD Fluid Motion Frames at the same time leads to a very significant increase in performance in individual games, at the same time there are problems that actually make this idea meaningless.

For the experiment, QuasarZone used the Radeon RX 6600 and GeForce RTX 4090 graphics cards. The main monitor was connected to the AMD graphics card to display the game image. The NVIDIA card was tasked with displaying game graphics. The principle of operation is that game frames are drawn by the GPU of the GeForce RTX 4090 graphics card, which uses its own DLSS 3 Frame Generation technology. The output image is then sent to the Radeon RX 6600 graphics card and interpolated again using AFMF before being displayed on the monitor.

The experiment showed that the combination of DLSS 3 FG and AFMF increases the average frame rate in Cyberpunk 2077 by up to 290% compared to the original resolution. Without using AFMF, the performance increase in the same cyberpunk game is around 200%.

“Using NVIDIA Frame Generation and AMD Fluid Motion Frames simultaneously actually results in significant improvements in graphics performance in terms of average frames per second. However, the impact of such a frame generator pipeline on the 1st percentile score varies depending on the game. In the same Cyberpunk 2077, the use of AFMF contributed to its increase, and in Ratchet & Clank: Rift Apart, on the contrary, it led to its decrease. Using AFMF alone in Call of Duty: Modern Warfare III 2023 resulted in an increase in the 1st percentile score, but using AFMF in combination with DLSS 3 FG saw a slight decrease in this value.writes QuasarZone.

It was noted above that using NVIDIA Frame Generation and AMD Fluid Motion Frames simultaneously is not without compromises and does not always provide the best gaming processor experience. Although the average frame rate increases in this case, the 1% FPS display may decrease. This indicator, in turn, is used to demonstrate the smoothness of the gameplay. In other words, despite increasing the average frame rate, the overall smoothness of the game deteriorates at low FPS of 1%.

The simultaneous use of NVIDIA and AMD frame generators requires the use of two graphics cards, which has a negative impact on power consumption. Also, it is necessary to run games in full screen mode as AFMF does not work when using other display modes. As an additional graphics card, you need at least an average graphics accelerator, since AFMF on the same Radeon RX 6600 loads your GPU by 90%. In other words, the capabilities of a graphics card at the level of the Radeon RX 6500 XT may not be enough.

It is quite clear that AMD and NVIDIA will not combine their frame generation technologies on an official or unofficial level. Furthermore, artificially doubling already interpolated frames will almost certainly lead to errors in a given game. Nevertheless, the QuasarZone experiment seemed very interesting.
