Cannot disable VSync after upgrading to Unity 2017.3

Questions & Answers
1

Hello,
I recently upgraded to Unity 2017.3, and while I have V Sync disabled in the quality settings and I do not have any instances of Application.targetFrameRate in my scripts, the profiler is showing VSync both in editor and on Android, along with capping the game’s framerate.

I have been unable to find any new settings relating to vsync or reasons this could be happening. If anybody could point me in the right direction it would be very helpful.

Thank you very much!

I do not know if this is correct but the way I found to work around this problem was leaving the Every V Blank option enabled. Hope this helps .

This fixed it for me:

I have to manually call this at the very beginning:

        Application.targetFrameRate = 5000;
        QualitySettings.vSyncCount = 0;

At the start of my script to turn it off. The top line for the target frame rate can probably be left out (just set it to some huge value to test), but running the build causes the vSyncCount to be set to 1 which forces vsync on. I don’t know why since I disabled it in the editor… but I guess the loader at the start overrides everything and we have to manually turn it off.

After doing the above, the problem resolved for me. Using Unity 2018.3 currently but plan on upgrading soon.

I don’t care much about the editor, but in the actual build I want it to be off… or at least toggleable. This solved it for me. I also had to play with the vsync option in the nvidia control panel just to be safe, but the above stuff I wrote was the final step needed for me at this time.
