On a recent core2 duo or quad, even software rendering isn't that bad. > I guess that that proves that the problem lies with the NVIDIA driver and its > inter-relationship with the Mesa libraries, which one has to use if one > builds > one's own "OpenGL" programs.

It was nvidia's decision to drop support for older cards from their recent drivers.

Get a card that is well-supported by the drivers in the FreeBSD kernel and Xorg/Mesa. Currently that means Intel's on-board graphics or boards with ATI/AMD radeon chips, except for the latest chips. AMD released docs for those chips some months ago, and the drivers for accellerated 3D are still evolving. Accellerated 3D works fine on my Radeon X1650 equipped card with the xf86-video-ati driver and the drm.ko and radeon.ko kernel modules.
