as i already stated....Play the game as you like it...never try to go for other Cfg's and useless command....
commands are not useless.
the thing is cs is like ur personal computer.
u have to know your settings.
so that if u sit on sm1 elses computer u must know wat can be different from your own cs.
that way u always play on the same settings thus a very consistent result.
now the way to do it is make a cfg so u dont have to remember like a hundered commands to make everything the same as your DEFAULT settings.
u just execute ur cfg and voila 90 percent of your settings are done.
things that do not change by executing cfg are:
Resolution
out of game sensi
r_mmx
sv_minrate
sv_maxrate
sv_minupdaterate
sv_maxupdaterate
sys_ticrate
and some others which i dnt remember rite now.
