However, for a particular paraview dataset that I happened to have lying around it is slower than direct rendering by a factor of about 2. That may be related to the fact that this particular scene has wiggly tubes with structure too small to show on the screen, so there is a high ratio of data to things that actually get displayed. For the same scene, unaccelerated indirect rendering is much slower than accelerated, perhaps by a factor of 10. So when you can't use direct rendering, acceleration is a big help. Once I say -wgl, direct rendering no longer works. That is, if I don't set LIBGL_ALWAYS_INDIRECT, then I get a long (infinite?) sequence of errors like this: X Error: BadMatch (invalid parameter attributes) 8 Major opcode: 73 (X_GetImage) Resource id: 0xa0039a I attach my XWin.0.log from a test in which I first succeeded with LIBGL_ALWAYS_INDIRECT and then got the error above without it.
