And you can use cubemaps for lighting too... I think Sswift posted a demo about that. Obvious advantage is of course that you might not need ANY "true" lights then and yet get much richer lighting than what you would get even using several "true" lights (which would be dead slow too of course).
Cubemaps do not slow you down because it's a hardware thingy... but if you don't have it in HW then you can't run the app that uses them. But even GeForce1 had that so...
Oh, and if you are going to do cubemaps reflections that are re-rendered EVERY frame you are going to see dramatic drop-down of your FPS.
