the stutter apprears from beggining to end at the exact same timings ( I would say twice per seconds ) as long as you have smooth 60 FPS in standalone or shipped or developpement.
make sure to test little projects, StylizedRendering is a really good example, you should be able to notice the frameskipping effect.
if you want to compare with and without the bug, its a bit tricky, but not impossible, you have to package the game in shipping mode, then with a 3rd party software ( I personnaly use RivaTuner, I totally recommend it ) find the “UE4Game-Win32-Shipping.exe” of the project you just packaged and apply a 60 FPS limit on it. if you do that, when you launch the game, the game will be 100% smooth, then try to put a higher FPS cap like 70 and you will notice the stutter ( actually even at 61 you should notice stutter, but I didn’t test it so I wont speak ).
