If it makes you happier, Optimus has the same issues under Windows. But you are quite lucky that you can use your nvidia card at all, I couldn't get unofficial driver running. I personally liked the early Optimus releases which allowed to turn off that damn thing in the BIOS. I'm perfectly happy with my battery being drained, I just want to be sure which card is used and how.
