I can't say I have ever seen someone of those who "cry about others having an advantage 'cause of a better cfg"
I don't like that they remove the option of setting a maxfps and such, but I don't like that higher framerates give less recoil and higher jumps and all those advantages...
IW should just let everyone adjust fog and debris stuff etc. in the graphics options of the game.
That would certainly prevent some whining in the long run.
