Publicly it appears to be a new article on their netcode here, apart from being a sentence or two it doesn’t make much sense.
“We’re using the Dead Reckoning system which means not sending data that isn’t needed, along with other systems and refining them to ultimately have scalability in the future. The impact on bandwidth won’t be major, but performance on servers and clients is our big focus right now and later on we’ll continue to optimize the network code with a more careful eye when things are looking good on performance.”
Interesting to note they have been experimenting with running Cryengine as a server, headless… Don’t have to explain to you why that’s a bad idea. Initially I thought they were joking. This is an attempt to manage clients in an attempt to fix physics issues, location issues, mapping, 64 bit on the server side. Based on what I can extrapolate they are trying to reverse engineer a new type of server without the graphical head to handle server functions to run from console and to develop it from there. I wish I was joking.
Such a broad subject there is no actual subject matter of specifics. Scalability without changing the fundamental architecture will not achieve results. If anything it’s a waste of time, effort and resources IMHO.
