There isn't a list of features this can be added to?
There have been various lists at various times. At the moment, we have nothing but short-term plans. We design OGD and sell it. Then we use it to develop OGA. While that's going on, things change. Prices change. Technology changes. And many of the things that people THINK they need turn out to be less necessary, while others discover needs they didn't realize. > > > If you want to play high-end games, you're probably > > going to use the latest nVidia or ATI on a Windows PC.

No, but like I say, we'll then put a bridge in there to make the PCI-X device work with PCIe. > > > > > > > Single-head: output selectable between DVI, VGA and TV-out > > > OGD will have two dual-link-capable DVI connectors.

I've never been able to get anyone to commit to that, although plenty of people have volunteered to help at various times. This is the nature of OSS projects. _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
