I kind of stopped playing FSX due to the stutters that I get with the newer nvidia drivers. I bought a GTX260 hoping the issue would not carry over to the new card, but it did. I don't think I can use ther 169 drivers with this card, so changing drivers to cure the problem is not an option anymore. I don't know if a new install will fix this as others have reported the same issue. So I might be done with FSX for a while.
