There's no way to unlock locked cvars simple as that.
Half your config is useless and the funny thing is that everybody is copy&pasting your useless cvars, shows that they know just about as much about the cvars and game as you. Comes down to "nothing"
@ s_LockListener
Anything that begins with s_ are sound options.
i was thinking the same thing...when he said the patch broke his game.
the one command that you might want to set is vt_maxPPF
i have a quad core so i set it to 16 but you should enable the console
and try a race map with vt_maxPPF 8 then restart at 16 then 32....ive seen it can hurt my performance at default vt_maxPPF 128
with it set to 8 i get the best framerate but some popin.
