Quantifying Lag / Shaking / Rendering Ability

Title kinda says it all.

What are the ways we can quantify how "bad" lag or shaking is or how hard YSFlight is working to render a map or airplane?

FPS seems like a highly relative measure as it can very widely between users and seems to largely depend on hardware.

I can't speak to the others, but I just did some tests to quantify distance shaking:
By my math, YS has 24 binary bits of floating point precision. This means just visible shaking (roughly 1cm precision) occurs beyond 80 miles from map center. See the following table:
