Unfortunately no. In fact the Gallium EGL/R600 doesn't support flip on vsync at all - eglSwapInterval is always 0. The output is a standard 60Hz LCD, plus I do get different, (but still low in absolute terms) frame rates with different chips. Off the top of my head: - HD5430 - 120 FPS - HD6450 - 140 FPS - HD6460 - 70 FPS - HD6750 - 400 FPS - HD6760 - 240 FPS I do think there is something fishy with the page flip though, which I am planning to investigate today. It is way too slow - a render loop which does nothing but a eglSwapBuffers() (no actual rendering whatsoever) runs at only 350 FPS. It should be either 60FPS, or thousands. regards, Tzvetan _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
