Does Worlds work with 3D graphics cards?
Worlds does support the use of 3D graphics cards. Please read the section on 3D Hardware Acceleration Return to Top When I try to voice chat I get the message “Your sound card doesn’t support full duplex”. There are two possibilities. (1) There may be sounds currently playing on the sound card. Sometimes people have fancy sounds set on their operating system so that windows plays a little noise when a button is clicked. In other cases, there might be some other program playing music. We try to turn off any Worlds sounds immediately before activating VoiceChat, but if you can hear sound, then there might be a problem. In either case, if you can hear sounds as you try to activate VC, then one channel on the card is already occupied, and the card will report to the VoiceChat module that there are not enough sound channels to support the requested activity. (2) The other case is that the sound card really doesn’t have two channels. In this case the only option is to upgrade the sound card.
