  • Reality is merely an illusion

As I am still running Anteworld on a small Nvidia laptop (I look forward to running it soon on a recent CPU/GPU workstation),
I'd like to understand something about performance vs. remote access :
- the engine is server-side downloading the necessary portion(s) of the world (mainly terrain I see, .wad files) based on the user position in the world, exact?
- the corresponding downloaded datas are then cached or stored on the local disk,
- when the user is somewhere at a position where there is nothing more to download, the download stops and there is no more any interaction with the remote "streamer-server", is there ?

BUT does the download affect the performance so much on the user-side that it is necessary to stop any interaction with the remote server ?

Of course it depends on the platform and on the remote server, but on a serious desktop, multi core, with good Ram and GPU, why not run a quasi-continuous download ?

In other word, why not pre-store some tiles ? even if they have no immediate usage ? you would say which tile... I don't know, more probable would be neighbor ones?
of course, it the user jumps vertically into space, then rotate 180 degrees around the planet, this pre-download must be stopped at the profit of the new position...

Performance isn't affected, the download runs in a separate thread - well, runs is a wrong word here, waits. Why it doesn't download continuously - well, at the moment we are limiting the bandwidth, pre-downloads would unnecessarily suck more. But we plan to serve the data for registered users from the cloud later, which should run at full speed.

Beside, you can download the whole 13 gigs of data via a torrent file, see : http://www.outerra.com/forum/index.php?topic=645.msg8073#msg8073

Ok, you'll need 13 gigs freespace on your harddrive, but what is 13 gigs nowaday ? :)
I did it and now I can go anywhere in Outerra and all is well!

 thank you XZS but I know that, as I already torrent-ed all the terrain weeks ago  ;) 

my above question is general, just for having a confirmation about a potential continuous process of "feeding the beast"
