AMD Smooth Motion Frames with Prepar3D

[level7]

Anyone with an AMD card try out the new stable release Smooth Motion Frame driver? Theoretically this should work with P3D V4/5/6 too given it's a DX11/12/12 game.

Requires full screen and disabling VSYNC though. I'll try it a bit later and report back 😛

seems to work ok for me! AMD users should definitely try this out!

get about double the frames from before, although they suggest the base frames should be 60+, it looked pretty smooth to me when i was under that.

Hello Level7. Did you find any artifacts when using P3D (either v4 or v5) with AFMF?

How did you get it working? For me it keeps saying "Inactive: Incompatible with the game's display mode.", even though VSYNC is off and P3D is fullscreen... :/ What P3D version did you try this with?

P3D is not a true fullscreen program, it is actually borderless window which may not work with Smooth Frame.

I'd believe that. However, Nvidia Inspector's half refresh rate V-sync (or 1/3 or 1/4) works for me, despite being just a borderless window. I don't remember what did I set in Display options, but I can share tonight as soon as I get back to my rig.

I used P3D v5.4. I used the AMD driver overlay to see the enhanced frame rates which was roughly doiuble the Shift+Z frame counter. It was enabled in whatever P3D full screen was by pressing Alt+Enter.

Because I prefer to fly windowed I didn't test it out too much. I didn't immediately notice any graphical glitches.

I've also used this a bit with MSFS and also haven't found any significant glitches.

Hi Luis. Can I bring this thread up again?

I am also getting a notification that Fluid Motion is not working due to the grafic API. Would you mind sharing your settings?

[Luis Hernandez]

I never had an AMD GPU. I was considering one, until Lossless Scaling appeared (with its 2X and 3X frame generation modes). So no, I don't have any Fluid Motion settings to share, sorry.

There's an AFMF2 now

I realized the original implementation was really tanking the frames for MSFS because it was eating VRAM that I didn't have. Their implementations do seem to be more for if you can already get 60 fps to start. I've gone to the LSFG instead and it's been working well.
