Increased input lag / delay in Standalone build when having low frames per second or VSync enabled



How to reproduce:
1. Open attached project "DXGI Flip" and scene "SampleScene"
2. Open Standalone (attached in the project directory)
3. In Editor, Enter play mode
4. Compare Editor and Standalone movement latency

Expected result: The latency is the same between Editor and Standalone
Actual result: the Standalone build is way more unresponsive when compared with the Editor

Reproducible with: 2017.4.31f1, 2018.4.5f1, 2019.1.13f1, 2019.2.0f1
Could not test with: 2019.3.0a11 (VSync in Editor is not applied)

    This is still an issue 2020.3.15f2, I'm almost 100% certain that it was never fixed, and should not have been marked as fixed.

    This seems to still be an issue on Mac. I'm using 2019.3.9f1 and am experiencing it with Mac builds.

    I can confirm the same problem. In the editor everything runs smooth. In the Standalone build on PC (Threadripper CPU, 1070Ti, 32Gig RAM) there are massive input and physics calculation delays. This is up to a second delay, completely unacceptable.

    I also get this issue using 2019.3. The editor runs snappy. The standalone also gets good FPS but responds much more slowly to input.

    I also have an issue with this in my build. Doesn't happen in the editor, only in the build. Happens with 2019.1.7f1
    Interesting to add that it only happens on my gaming laptop, but not on my old desktop. Also doesn't happen with older versions.

    I've confirmed that this regression is still present in 2019.3.0f6, with a couple of minimal demo projects. The issue isn't there in 2018.4.10f1.

    This doesn't seem fixed to me in 2019.3

    The same happens on my Mac, too. The standalone player has significant lag with vsync on and the editor does not.
