I used bilinear interpolation to smooth out most artifacts caused by this speedup - though you can still see some artifacts around the boundary of the obstacle.

I ignored the viscous diffusion term from the Navier-Stokes formula to encourage better vortex formation (the implicit advection solving I'm using creates enough diffusion on its own for this system).
