measurement of metric PC Latency

[xcorrnner]

I am insterested in measuring the pc latency and end to end system latency. and the nvidia provides a pc latency and render latency in the in game overlay. And I notice that in previous commit, you implement pcl with the fv sdk. why removing it in the current version. it's still a useful data to analysis the performance

We will add PC latency from an Nvidia SDK soon. Check upcoming betas/releases.
