It's been a while since I last had X + accelerated 3D on any of my
systems here (my gaming box's running W7), but it would be my guess
that, while Nvidia's libraries *were* configured as the GL
implementation to be used, in the process of the last driver upgrade
they got overwritten with upgraded versions, running things that
should have referenced them failed and defaulted to mesa's libraries,
and you got stuck with CPU based 3D rendering. Upon using eselect to
set it to Nvidia's again, however, you refreshed the links to the
proper, updated, libraries and things started using the GPU again.

This is, of course, entirely a guess, and is at least moderately
broken by this from glxinfo:

server glx vendor string: NVIDIA Corporation

Still... it's the best guess I have at 1:17 AM here, my time.
