Attempt to calculate actual refresh rate (i.e. a CPU-GPU synced Mhz), no real success. Anybody have any ideas?

Is there no indication from the game when the screen refresh should occur? No, not what I could find, we currently calculate the refresh rate and m_VBeamPos from the CPU ticks progress. That works perfectly if the CPU and GPU is perfectly synced as in the single core and no-idle skipping mode. So I guess it's possible that the game doesn't indicate when the screen should be refreshed, but rather that the hardware calculate that from the CPU ticks progress. That leaves us with a problem in the dual core and idle skipping modes to calculate a CPU-GPU synced CPU ticks progress.
