Any plugin to estimate the framerate?

[Doriandal]

Is there any plugin that can estimate the framerate based on the difference between frames, tearing, etc?

It could be useful and not that complex to writte i think.

I don't understand. Can you describe what you are trying to achieve in more detail? What is your source and what is your goal?

Probably what DigitalFoundry is doing http://www.eurogamer.net/articles/digitalfoundry-what-gta4-did-for-us
(on consoles they take lossless capture and count frame duplicates to measure fps)
