sv_maxrate

[Drocona]

Wait, do you mean that like a customer sets the sv_maxrate it won't go back?
or
When a client sets his OWN rates to something higher than the server maxrate it won't be limited by the server?

For the first one, shouldn't be possible, the sv_maxrate command can only be set at the start of the server, it will not change while the server is running.
For the second one, client rates are NEVER influenced/set by the server, the server however will NEVER send more bytes per second than the set sv_maxrate regardless of the settings clients use. Server (sv_) settings are completely different than the clients (cl_) and have nothing to do with eachother.
