In my experience, boasting about / demanding high framerates in FPS games are just a way of trying to hide personal inadequacies in gaming skill (and probably other places :lol:).
I retired plenty of people in networked Quake 1 games at university, running at a mere 15-20fps.
Consistency of framerate is *far* more important. Give me a solid 27fps over a highly variable (even if on average faster) framerate any day.
