Regression

Yes

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

Windows

-

How to reproduce:
1. Open attached project "DXGI Flip test.zip" 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)

    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.
