Different fps shown in MSI afterburner and MSFS

[MauBen 82]

Can someone please explain to me why the fps shown in MSI afterburner is double the fps shown in MSFS developer mode?

I suspect the developer fps is the correct one, so what is MSI showing?

I do have 2 monitors, but even if I disconnect one, the MSI fps is still double the MSFS one.

This is not a problem, but I’m just curious to know why this happens.

Thanks

What GPU are you using and if it’s a 40xx do you have FG enabled?

I have a 4090, but I am not totally sure what FG is. If it stands for DLSS frame generation, it is turned on, so is that what is giving me the higher fps in MSI afterburner? I guess that would make sense why the developer FPS count does not see the extra frames since they are generated in the GPU. 

It also makes sense to me now because with my earlier 3080, I did not have Hardware accelerated GPU scheduling, and this is apparently required for DLSS FG.

Mystery solved I think

Thanks very much 👍👍
