Since I have my GTS250 (1/2 year) I never managed to get the driver's AA and AF working (i.e. disable them in FSX and enable AA and AF in the NVidia control panel). For me, only FSX' built-in software AA and AF have an effect.I tested with an ATI adapter, there it worked with the drivers, but I got small display abnormalies and switched back to the NVidia adapter.I even tried NHancer, no luck so far. Spent already several hours trying to resolve my problem without success.Is there a working method to make my GTS250's driver do at least AA in FSX? Guess I better let FSX do software AF since the results with the ATI adapter were really bad.

Using nHancer and undchecking "Enhance in-game AA setting" finally did the trick :(. Thank you a lot!
