Thx booker,
\com_maxfps\83\rate\12500\cl_maxpackets\66\cl_packetdup\2\ <- in console n1 :p)
4.3 come with unlock of the cvars sv_fps and snaps; but need more cvar in setu.cfg and with a litle IPTABLEs i can test rate, cl_maxpackets for man with strange connection, urt client or OS.
Like that all same game and can optimize servers
