First dvar is my main cfg
second is my old one (ugly as hell but uno, fuck it)
i forgot the 3d one, just check it out
fourth one is for ssao adjustment (yes, you can adjust the ambient occlusion.. just open the dvar and u can play around)
5th one has the dof settings for cinematics
6th one is quite nice, its just a config with filmtweaks, the basic filmtweaks (like in the mw2 feed servers)
7th one is again unknown for me xd
8 is empty
the 9th one has all the commands in mw3 possible (dont exec it, u can find the commands there)
10 is to set everything back to normal (chat, radar, killfeed, etc..)

config_mp is for the best quality ever. tripp's config_mp fucks up your sensitivty and stuff so mine is bettah
copy the config_mp over your own config_mp (which is in 'common\call of duty modern warfare 3\players2', basically the players2 folder in your mw3 folder..)
BEFORE YOU DO READ THIS:
if you have specific controls set (binds, controls, whatever), right click my config_mp, properties, and uncheck 'read only'
now open it and delete all the 'bind' commands, and open your own config_mp (which is in the players2 folder) 
copy all the commands that start with 'bind' and paste them in my config_mp (on top, alphabetic!!).
now save it, close it, right click, properties, and check 'read only' again (so its on)
now copy + paste it over your own config_mp :)
