DD seems to be too much to handle for my old laptop (500 MB shared RAM, 1.8 GHz single core). As soon as I reach the login screen my browser hangs up and my whole system gets majorly slowed. The only way out of this is to close my browser. It's really quite silly how the login screen with two lines to enter stuff into and one button does that. Even on my desktop pc firefox gets a bit wonky when DD finishes loading. No trouble at all with the game proper though. I just cant get there on my laptop.
Any tentative system requirements? Any chance something is wrong with the login screen?
