Which X are you using?  XFree86-4 from ports (what I would call "the most 
recent") provides no hardware opengl acceleration on nvidia cards.  The 3.3.6 
XFree (the default X that is installed with FreeBSD) can get some TNT support 
through utah-glx (ports/graphics/utah-glx), but that will still be very slow 
compared to even a voodoo3 because nvidia never released enough info to get 
DMA working.
