It was fast enough 3 days after launch too...Pondering doing a copy sometime to at least see the upcoming content, now that 6000-series cards have some official support on the way. I'm guessing the process is a lot faster now than on launch day, can anyone confirm this?
My transfer took like 20-30 minutes or so
But be advised the latest 6000 series drivers, while no longer hard crashing the client, still have some issues with a certain shader that apparently is inducing some color issues on atmo planets (but it's correctable using shader manipulation tools for the ones willing to go the extra mile)
