I've seen a similar question asked many times here but nothing seems to be working.
When I go to filter -> render -> lighting effects it seems to pop up some kind of options pane for maybe a quarter second while it's thinking, but once it's done all it does is create a duplicate layer called "lighting effects". I never actually see the options.
I've updated my drivers, and I just installed cs6 today, without importing any of my old settings from before.
Any idea what's going on?

You're the second or third person with an open thread on Lighting Effects problems at the moment.
Try the various graphics processor options provided in the Edit - Preferences - Performance dialog, [Advanced Settings...] (and remember to close and restart Photoshop before testing).
