Use Unreliable RPC instead of OnPhotonSerializeView

Hi
I want to use rpc to send player states instead of OnPhotonSerializeView.

I changed
this.OpRaiseEvent(PunEvent.RPC, rpcEvent, true, options);
TO
this.OpRaiseEvent(PunEvent.RPC, rpcEvent, false, options);
in NetworkingPeer.cs

does it make rpc unreliable?

I prefer using rpc because OnPhotonSerializeView doesn't send data in a fix rate and I can't control send rate but with rpc I send data in every 5 fixedupdate. so it send data every 0.2 second.
