A very high end one.
I unfortunately cannot reproduce the results with with VBOs disabled, so I had to settle with using Sumz City, getting 16 FPS with the entire city in view from a distance and 13 FPS upclose, using 32xS [Combined: 2x2 SS + 8x MS] antialiasing, PCSS shader with 8k textures, bloom, and brick tessellation. Default max shaders gives about 40 FPS from a distance and a somewhat unstable 45 FPS up close (on the hill). GPU used is a GTX 1080.
