No / depends on the visual library.
Dx12 has no real FPS output info.
The engine numbers are fake btw, not factual.
Based on best guess due to ms frame cost.
Technically even Fraps and others still have dx12 issues or just flat out don’t work with dx12… Or rely on mostly best guess rather than accurate info as you might expect.
The best and probably only accurate output is going to be straight from your GFX card’s manufacturer software.
Msi afterburner or Nvidia’s shadow play.
Possibly the overclocking stuff on 40*0 cards - so for asus GPU Teak 3.
If you want the best guess the engine gives you, you can always output the value of it as a string 
That’s probably 1 / delta time
