Okay, this may come off as weird, or maybe not at all...
I was once obsessed with FPS, and no, not as in First Person Shooters but as in Frames Per Second. I learned to discern (or so I believe) the hitches in gameplay and associate numbers with them by making comparisons of games that ran at 60, 40, 30, etc. Now I don't do it any longer...to other people's faces.
My brother once-years ago by the way-got angry and told me to shut up about it, and I was like "dude, chill," but yeah, he was probably right.
The leftovers of my obsession are that now I can't watch anything blu ray because, let's face it, it does look pretty and sounds pretty, but the screen refresh rate (them FPS) is FUCKING uneven, especially in effect heavy secuences. Normally blu ray makes the attempt at running at 60, but sometimes you can see the rate drop as low as 24 that the damn thing is unwatchable to me. It's sad (and jarring) watching 60fps people trying to outrun a 24fps body of water. It takes you out of the movie comlpetely. I rather watch my ugly 24fps media that is even, at least.
Hmm, on second thought, I was probably mildly obsessed with the novels Atonement and Anna Karenina for weird reasons. Anna Karenina I can understand why, but Atonement? I'm a guy, damnit.
