It’s another packed edition of DF Direct this week, with our latest thoughts on Star Wars Outlaws, impressions on Nobody Wants To Die and the Visions of Mana demo plus a look at how ray tracing is being introduced into the next wave of EA Sports titles. However, the focus for this piece is on the release of a new technical preview for AMD’s Fluid Motion Frames technology – AFMF 2. This is the Radeon team’s second attempt at driver-level frame generation and if you have the means, I highly recommend checking it out.
First of all, it’s worth getting all of the caveats out of the way: driver-level frame generation can never hope to match the quality of Nvidia DLSS 3 frame-gen or AMD’s FSR 3 alternative. These technologies have deep-level integration into game engines that allows for much higher levels of fidelity from generated frames. AFMF is essentially FSR 3 without the additional information given up by the game, so in effect, it works in a similar way to smooth motion interpolation in TVs. The game frame is rendered, then another is held, and then AFMF interpolates an ‘in-betweener’ image to sandwich between the two.
With only screen-space information to work from, AFMF has to make a lot of guesses in only a very short amount of time, so more artefacts and errors will present themselves. However, similar to other frame generation techniques, generated frames are effectively strobing between standard rendered frames. The higher the base frame-rate, the faster the strobing effect and the less noticeable the artefacts will be. AMD typically says that 60fps is a good base-level frame-rate for FSR 3, so it stands to reason that AFMF would require a higher base fps level to better hide its inadequacies.
