You dont need to respect my opinion, just understand it
And yes, I might have "FPS sickness" as you say. It isnt particularly bad, but as long as I can tell that the framerate is below 60, I am bothered.
However, the monitor refreshes the image 60 times per second (60 HZ). That means that anything below that is a frame that is missing (dropped), and may or may not be noticeable depending on the viewer/player.
And this one isnt an opinion/preference, its fact.
If however you are on a display with G-sync or Freesync, then the monitor adjusts the refresh rate to match the framerate. That way, you never notice any dropped frames, as long as framerate doesnt drop too low.
It also doesnt produce screen tearing.
I got an i5 2500k, 8GB DDR3, and GTX 970.
My framerate doesnt go as low as 38, lowest I've seen is 41.
And it actually cant go as high as 60 FPS, so you're right about that. Just tested the game (latest version) today, btw.
It goes as high as 49, depending on how (or if) the scene changes.
My GPU usage is at 99% locked, almost all the time.
The game is severely GPU-limited, at least for me.
Anyway, as long as you're happy with how your game runs, then all is well.
But for me, I wanna see 60/60 FPS, and thats it.
