Now I'm confused. I thought we saw OCS already being tested in Evocati in that video earlier this week where the guy was walking around on the moon and the rocks kept popping into place as he got near them.
Rocks and trees popping into place are just because you don't want to draw all the rocks on the planet at the same time - the rock was likely to be in memory already. It's the same as grass surrounding the player but not drawn at a distance in most open world games. Thing is, you're not really meant to notice the effect.
OCS is all about memory, at the moment if you start at Port Olisar you're loading all the assets needed for every NPC / object in Levski aswell even though you won't draw them on the screen until you get up close to Levski. With OCS, only Port Olisar gets loaded, then once you start your QT to Levski, Olisar is removed from memory and Levski is loaded in the background.
Thing is, OCS isn't anything new. This is what every other open word game does. Normally they get it working at the start of the project, nor do they make a big deal about it. For example:
https://docs.unrealengine.com/en-us/Programming/Assets/AsyncLoading (I don't know Unreal) this is all about finding and loading assets in a background thread, this is the core bit of technology and a game would build some custom code on top of this to suit their specific situation. Although I can't find anything similar for CryEngine with a quick Google - which may explain why they have taken so long to implement it: they have to rewrite the core engine to make it work.
OCS is just the latest in a long list of technologies where CIG have invented a new term for something that already exists in other games, it's just that other studios don't bother talking about this stuff except to other devs at GDC. By calling it something unique it means that the idiot whales will only find the term associated with SC on Google and think that CIG are inventing new technologies. They aren't, they've just invented a new word for it and barely been able to implement it. We laugh at it, but it's a serious issue because it's just another part of the scammy marketing tactics used by CIG.
