thanx man,but i am not talking about fps here.
let us you have a CRT monitor,running at 1280*720,32bit color,85Mhz refresh rate,and you'r GPU is not that fast,you started the game,and decided to lower the resolution down let's say 800*600 to let the game run alittle more faster,now at 800*600 the screen became flickering,because the screen refresh rate is now 60Mhz.
that's my question:how you can change the screen refresh rate in the game??
