Can someone tell me what the last graphics option does? ASYNC UPNP DETECTION?
This question / problem has been solved by toxicTomimage
That's no graphic option. UPNP (Universal Plug and Play) is used to find devices on a network. I guess it's used to have ad-hoc LAN session or something like that. But a lot of people seem to recommend to turn this off in RoTT.
