I’m having a rather annoying problem with my picking implementation. I’ve done more or less as the documentation and the NeHe tutorial on the subject says and everything works fine when I run the app in a window. But when switching to fullscreen it takes forever, 0.5s to 0.7s, for OpenGL to “render” (nothing is being rendered since I’m running in glRenderMode(GL_SELECT)) the object being picked. I’ve done tests with over a hundred objects and it’s just the picked object that is causing the huge render time.
I appreciate any help or hints I can get on this one, I have a 16Mb Voodoo 3000.
