Nvidia has too many drivers and many of them may not work to well. lol :)

Nvidia, guru 3D, nhancer, Riva Tuner, and every other 3D forum you can think of is loaded with people having problems with AA in FS9 with nvidia cards, myself included especially with the newer drivers. It's certainly no secret or rarity. Some people have no problems, many other people do. Different systems have difference performance characteristics with the same drivers, a fact of life.After a re format and re install I had gone through multiple installations of 5 or 6 sets of drivers to get decent AA without having to use full screen mode or AA in FS9 (which created stability problems) and finally settled on 93.71 dating back to Nov 06 and I'm getting trememdous performance and image with or without full screen plus they are very stable. I tried Riva Tuner and was just starting to get up to speed with nhancer when it turned out these older drivers worked great so I had to do nothing else. I'm now at the "if it ain't broke don't........." so am not using either of the above.And yes I clean drivers in Safe Mode with Driver cleaner Pro and take all the rest of the necessary precautions.BTW if you use the free Driver Sweeper from Guru 3D it has a great little easy to use tool to recover your desktop icons in their approx. correct locations after using safe mode. Just take a snapshot before you start messing with things and then a "restore" when you're finished and your icons will arrange themselves reasosably correctly.

Of course as soon as I talk about how great my Nvidia card is working I log into FS9 for a quick flight and FSAA no longer works. LOL :-lolDropping down in driver revision is not an option so I guess I will just have to wait util a new driver fixes it. Great. lolDisregard my comments earlier, guys. My apologies.

Shane:NOW is the time to download, install and use nHancer!Chuck

>Shane:>>NOW is the time to download, install and use nHancer!>>ChuckStrangely, clicking the "FSAA" option in FS9 seemed to re-enable the FSAA. Forcing it in the CP didn't work, but checking this option did.That's strange.I will go DL NHancer as well ad run some tests.

It's not that hard to do, just download nHancer and fix the profile. Depending on your driver version, you might be able to remove the old FS9 profile, but either way, just duplicate it and click remove to disassociate the FS9.EXE file from default profile. Delete the profile you made, then create (not duplicate) a new profile from scratch and adjust the settings. It's a PITA because nVidia has a pathetic way of creating drivers now, but they locked the FS9 profile with the latest drivers, so you have to duplicate to prevent the driver from reading the default profile, then delete the duplicate and create one from scratch to get the settings to take. Trust me, I followed the instruction and it still didn't work. I had to follow the steps just right or FS9 looked like s$!|

That worked.Thanks!
