Mobile - Is there any difference setting VSync of FrameRate?

Hi there,

When we deploy for mobile devices, Android or iOS, is there any difference in:

Target device refresh rate = 60;

Application.vsynccount = 1 (FPS cap at 60 fps)
or
Application.vsynccount = 0;
TargetFrameRate = 60 (FPS cap at 60 fps)

Inside unity are they doing the same? is a huge difference?
Also on mobile even if u set VSync = 0 the device will keep doing own Vsync.
Can I have more detail explanation on this topic?

We have many projects here and some projects said that VSync = 2 (30 fps on mostly mobile) is a lot more stable than Vsync = 0, TargetFPS = 30.

Why would be that?

Thank you.

 

Thank you so much, two more question, I promise!

1- sleep implementation for frame pass is for Android only? iOS and Android? both will have similar results?
2- if my device is 90 refresh rate, setting sync at 2 give me 45 fps, but actually I want 30 fps. there is no other way than using targetFrameRate = 30?

 

Thank you!

 

ok, we are going for the VSync approach, the only issue we have is with phones that have 100 refresh rate.
