Hi Peter, The --dome implementation creates a texture cube map using FBO's, something that normally works fine, but last year NVidia updated their Linux OpenGL driver and broke its performance when doing texture cube maps and FBO's. Changing to Pbuffer improves performance in this instance, so it does look like a driver bug.
