pb_sleep 500
pb_security 0

PB_Security [0=no, 1=yes]
When set to 0, PunkBuster will accept all "update" files without verifying that they are authentic; the default is 1 which should not normally be changed except for LAN environments where there is no Internet Access and/or you fully trust the Servers you are connecting to
PB_Sleep [Period]
Holds the period of time (milliseconds) that PunkBuster "sleeps" between processing cycles; the default is 60; lower numbers will cause PunkBuster to process events more times each second which also has the effect of increasing the bandwidth used by PunkBuster; Players with a modem connection will probably want to set this as high as possible
