They offer a gamers edition (full screen only) and a professional edition (all goodies included). They support a wide range of chipsets.
I would be very curious to see some comments if anyone has tested this product, especially under non-gaming conditions, e.g. a scientific OpenGL app running in a window. Additionaly, a comparison to XFree's upcoming 4.0 version will be very interesting.
Unfortunately, I could not find any details on their implementation. XFree and PrecisionInsight have released a great amount of detail on their DRI/GLX implementation, and it sure would be nice to see how XIG did it."
Interesting points: This is of course not open source, and at $99 for the game version and $250 for the pro version, its not cheap, but it does support several cards that aren't supported under XF86 (like my Number 9 Rev 4 for example).
