I'm using an nvidia card with opengl version 4.5.0 (happy to give more info if needed). I did try and change the graphics_toolkit between qt and gnuplot but received fairly similar results. Something I noticed which might be of interest is that exporting a surface of similar size directly in gnuplot was many times faster.

​With gnuplot backend you can use
print("output.pdf", "-dpdfcairo")
that writes pdf directly (rather than going through eps -> pdf conversion via
ghostscript). On my computer it is more than 2x faster.
