Automatically scaling game graphics to maintain at least 60 fps -

i have noticed several graphics settings in games rely on restart of game take effect, having said, technically possible make game read computers specs , automatically , dynamically scale games graphics settings live, game maintains @ least example 60 fps. i'm thinking of games mmo:s might fps drops if there more people running around.

no

first of all: reading hardware not enough, programs interfere (use cpus)

then, when know (and able predict) cpu usage, there little cpu time left 60 fps not within reach
