I was checking out OpenSubdiv and noticed that on a Mac it’s not exactly “massively parallel”. Neither of OpenGL backends work (transform feedback one requires GL 4.2, and compute shader one requires GL 4.3 - but Macs right now can only do GL 3.2), OpenCL backend is much slower than the CPU one (OS X 10.7, GeForce GT 330M) for some reason, I don’t have CUDA installed so didn’t check that one, and OpenMP isn’t exactly supported by Apple’s compilers (yet?![]()
