With a laptop with Optimus technology, the problem is switching between the 2 drivers for the dedicated card and on board graphics. It does not matter which one you choose as long as you choose only one and don't switch at all. I have had better luck doing it that way than any other I have found. Now the good and the bad. If you choose the on board graphics for all the programs, you will not be able to play any of the more strenuous games. If you choose the Dedicated card, your battery life will suffer. That is what I did with my Laptop with Optimus and have had no problems. The idea is to keep it from switching at all because that is where you normally run into the problem.
