Only the installs were slow. Terrain streaming worked just fine right from the start (I played it from day one) - and once it’s cached on your machine, they can shut down the servers all they want, it’s still on your machine.
Were you streaming at 180mbps?
More than that, actually. I measured well over 250 over large cities. Others have reported more than 300.
That’s not how cache works.
In this case, it does. The cache for this simulator is a disk cache - and it’s completely configurable. You can manually designate its size and which parts of the world it’ll permanently contain. There’s also a default rolling cache (also on SSD - this program doesn’t even support hard drives), which does get overwritten over time.
The CDN to download the initial files were slow, the in game streaming was fine.
Yes, ownership sucks these days, but I don’t know how they’d technically pull this off as well without using a remote server. As a philosophy, if we’re purchasing games the only real choice is GoG, anything else ends up with us locked into some server-based licensing system.
