Are you using Windows or Linux?

Have you downloaded and installed the latest NVidia drivers?

Are you certain vtk is using those drivers?

Have you compared your vtk performance to a benchmark?

I've noticed that NVidia cards are not that great for vtk since their
polygon rendering count is not that high (at least compared to a Sun
with Elite3D graphics).

I'm still using a TNT2 card because a GeForce2 (borrowed from a
friend) appeared to be only twice as fast as it and it wasn't worth
$250 (probably cheaper now) to me to get a speedup of 2 (especially
when my Sun Elite3D at work is at least an order of magnitude faster).
