Is AFMF working properly?

[Kiwachu]

AMD just updated their graphic drivers to include "Fluid Motion Frames" which is basically AMD's frame generation technique (FSR3) on the driver level.

When it claims to be running properly, it doesn't look different until I turn quickly... then it's quite noticeable because it's turned off (or skipped) in fast motion, but the frame-rate is even lower than usual (due to the overhead involved), so every turn feels like micro-stutters by comparison.

I know that AFMF is a lesser version of FSR3, getting less data to work with (like motion vectors), so maybe these issues would be fixed if it was properly added to the game?

FSR and DLSS should be standard in all 3D games... isn't this game an Unreal game? Don't they have a drop-in API (or whatever) for FSR for Unreal?

FSR and FMF are very different tech.

FSR is upscaling, you must have the game set at lower resolution than your screen, so say you have 1440p screen (QHD) then you set your game to run at 1080p (FHD) and AMD's FSR tech will upscale the frames to 1440p.

FMF is new, it's actually generating new frames, it doesn't care what resolution you run at. The key for FMF is it's actually only good if you are already getting 60-70fps, turning it on when you're getting 25-40fps will just result in a blurry mess.

Yeah, the naming of the techs are also a little confusing.

I've tried both FSR through the in-game implementation and the driver-level one, but it doesn't seem like any resolution changes help, even running at 1K (1080p)! I seem to be getting around 60 to 75 fps.

(Similar results for the quality settings, too. From potato to ultra, it doesn't seem to afffect my framerate much.)

Yeah, and I think it's working, but this is a lag-sensitive game and I could actually feel the difference in responsiveness.

What's more concerning is why I'm not getting much of a performance difference from the differing settings. 🤔 I'll compare 1K potato to 4k ultra... there has to be a noticeable difference there.

Something isn't right...

VSYNC Off
Framerate Unlocked
Super Resolution Disabled

1K potato (no scaling): 80fps average
1K ultra (no scaling): 80fps average (zero change?)
1K ultra (perf scaling): 72fps average (less perf)
1K ultra (qual scaling): 71fps average (less perf)

4K potato (no scaling): 78fps average (only 2fps less than 1K?)
4K ultra (no scaling): 65fps average
4K ultra (perf scaling): 68fps average (only gained 3fps at -60% pixels?)
4K ultra (qual scaling): 67fps average (only 1fps diff from perf mode?)

This doesn't make any sense...

It's a little more complexe.

FSR 2 is just upscaling.
FSR 3 is both upscaling and frame generation.

AFMF is just frame generation, similar to the frame generation used in FSR 3, but managed in the driver of the CGU instead of directly in game for FSR 3, for a result not as good as with FSR 3.

I hope FSR3 is added, this game needs frame generation.

Also to make it more confusing, AMD and Nvidia's naming scheme for their upscaling and frame generation tech aren't the same, either.
