Not with XP you don't. There are two sets of drivers for Windows, the XPDM (XP Driver Model) and the WDDM (Windows Display Driver Model). The latter is for Windows≥7, hence the differentiation in the manual. The XPDM model which is used by Win<7 doesn't have 3D support in 6.1.x yet.

Exactly. The 3D support for WinXP doesn't exist anymore. If you want 3D support for WinXP, you should stick with 5.2.x or 6.0.x.

There's already 6.0.14 out there, and there are going to be plenty of updates. I wouldn't worry about that. My gut feeling tells me that by the time that 6.0.x is not supported anymore, the developers may have found the time to implement 3D support for the XPDM drivers.
