--- Comment #8 from Evan Goers megatog615@gmail.com 2013-09-15 18:37:03 CDT --- I could test it again, but I think it's been concluded here that the effects won't work at all because pbuffer support has been removed.
Usually I don't touch bug status unless told to do so. I would like to see if it works again before doing anything though. I have since switched to NVIDIA so I'm wondering now if that would have any effect.
