I remember hearing somewhere that a screen's given frequency (in Hertz) is directly related to FPS, and that it's a fixed number. From what I understood (and I may be wrong here), the screen's frequency stays the same and the computer needs to bend it's data feed to work with it. This would mean for example that if a game was running at 30 FPS, the computer would send each frame twice, so that the screen would get a neat total of 60 frames each second. For a game at 20 FPS, the computer would send each frame 3 times, for 15 FPS, each frame is sent 4 times, etc.
My confusion (and the reason I doubt the above assessment is true) comes from the fact that a lot of benchmarks seem to be given in FPS that aren't a factor of 60. How then would a game that's running at 26 FPS send it's data to the monitor? My friend tells me that it just picks random frames and only doubles the ones it neads to come up to the nearest factor of 60. This (he claims) is why you can sometimes feel something is subtly wrong with an image, but can't quite put your finger on it. Your eye can just catch the frames that are lagging, and they stand out in comparison to the frames that have normal frequency.
Can someone please give me a more thorough explanation to how FPS and screen frequencies work in relation to one another, or at least link me to a webpage/video that offers a nice explanation of it?
