Thanks for refreshing my memory, Erik. Indeed OpenSWR was it. George, the geometry is quite smooth and it doesn't look complex enough to justify 130k triangles. If the application has some sort of tunable NURBS tesselator, I'd tune it down so it spits out fewer triangles. That would increase llvmpipe performance without much visual degradation.
