There is an OpenGL-based renderer in the current development sources.
See the following post for info about a recent snapshot:

I tried it with your script (though I omitted the "+chirp()" part
because I don't have that package installed).  On my system, it took
around 30 seconds between the tic/toc calls and maybe another 10
seconds to render the plot.

Would you be willing to pay for better graphics in Octave?  Are you
able to contribute to the development of Octave in some other way?
