Hi, guessing wildly, I'd say this is due to the fact that PyOpenGL 3 uses ctypes instead of native bindings, although I didn't expect it to be that bad. Unfortunately, I can't try out accelerated rendering on my own machine now (thanks to some not-mentioned major graphics card vendor who is somehow unable to put out drivers that run stable with SMP systems, way to go!). Could you provide a small test script and some timings and I'll try to work it out with upstream. best, Torsten -- Torsten Marek <[EMAIL PROTECTED]> ID: A244C858 -- FP: 1902 0002 5DFC 856B F146 894C 7CC5 451E A244 C858 Keyserver: subkeys.pgp.net
