Greetings, Tapani! Yeah, the “included” openGL emulator that is part of the basic Vista driver is not just slow and buggy, it is also incomplete. Any software that requires a full openGL driver implementation will fail- for example, Second Life. And even those that do work are incredibly slow.

I’m pretty sure that ATI will eventually release an OpenGL ICD, but it seems doubtful now that they’ll do so in time for the initial release of Vista (I.E.: by January).
