Higher FPS and higher performance aren't necessarily identical. Give me a say year-2016 machine and I could target 300 FPS with what currently reaches 30 FPS, but no-one except some GPU geek would notice. Or I could use all that added performance, do many more interesting things at a much higher scale than today, at once -- physics, fluids, crowds and all other kinds of sims -- by still targeting "only" 30 FPS.
