Those upgrading to the latest 190.62 drivers should know that Nhancer will not work with those. If you stay with these, uninstall Nhancer until an update is released.As for the 190.62 drivers themselves, performance wise they are about the same with FSX on my GTX 260 as the 190.38's (with Nhancer)

Agreed, spent all afternoon trying to get Nhancer to work.Used driver cleaner as well, did a rebuild of Nhancer.Ended up going back to the 190.38 with no problems...Using win 7, 64 bit and the did use the correct 190.62 win 7 64 bit driver.Trevor
