I have a problem with frame rate configuration.
In case PVRShell is used, RenderScene is called on each v-sync.
If PVRShellSet(prefSwapInterval, 2) or eglSwapInterval() is executed,
the RenderScene is called at a second of v-sync.
Is this correct?
I tried with SDK demo program, but it seems not be effective.
I set the swap interval in InitView()
