There was an error with the intial content installers, they've been corrected, so try redownloading them and installing the content again. (They were getting installed with an extra folder that caused D|S not to recognize them properly). The interface code hasn't changed in any way so as to make it any slower than what was present with the Alpha, so that shouldn't be any differen for you, the last I heard. There have been several people make mention of the renders taking longer than that of P4, and that is true. Though, when you combine the more accurate OpenGL preview to the equation, since the preview is so much more accurate than what most of us are used to seeing, you shouldn't have to render quite as much. One of the biggest issues that affects performance is the video card, so the better the video card you have, the faster the interface should run. Thanks, please be patient, remember, this is only the first beta release, it's not finished yet. :) Steve
