I have completely understood that point. But as I mentioned, I cannot control this feature in mythtv as of version 0.24 any more. This option has been removed.

I'm running everything with "__GL_SYNC_TO_VBLANK" env var set, so OpenGL-apps sync good enough (though Compiz is not 100% tear free). This variable should be same setting that is present in nvidia-settings.
In my case I just have the "NVRM: os_schedule: Attempted to yield the CPU while in atomic[...]" error message. The "os_raise_smp_barrier()" problem, I don't experience.
