Arduino Hardware FPS monitor?

[werto165]

Just thought of a cool project depending on how you look at it. 

 

Anyway it's an hardware FPS monitor, it looks like this(the display): http://www.engineersgarage.com/electronic-components/7-segment-display

Is this project feasible in anyway? Keep in mind I have limited programming knowledge(I know a little c# doesn't really apply to arduino). I could either do the segmented LED or a dot matrix version of the display. 

Is there a program that fetches the current FPS?(that I am able to manipulate) If so what program?

I wonder if there are open-source software out there that calculates your current FPS. Open-source is preferable since you can fetch the variable there, have you googled enough open-source FPS software?

Apparently programs like FRAPS put a hook onto the draw commands, so they can tell when a new frame is being drawn. This is does not seem like an easy task.

 

You could try disassembling FRAPS or Afterburner, although that may violate the license agreement, and trying to figure out how they do it.

I'm guessin it's also possible to hack into the signal going between the monitor and computer, they have "newframe" commands. However, an arduino is no way near fast enought for that. (I'd think unless there is something handy like a frame-clock line in the cable but I'm not familiar enought with the standards to know).

 

I wouldn't know how to do it in software, since this is something that get's done by the GPU.
