   Stencil Buffer problems
  I have a Geforce 4 Ti 4800.As far as I'm aware I have the latest NVidia drivers.When I enable Stencil Testing my program slows to a crawl (and the stencil testing doesn't seem to work either but I think that's due to other bugs).  Is this simply a driver issue?   
  Heh, I think I may have found the problem, I'm programming in python and using pygame.  Pygame doesn't sem to have a way of requesting the use of the stencil buffer.  Anyone know how?
