Is the AA you were overriding to possibly super-high and maybe by cutting back just a bit you can have some AA without any slowdown?

Also, what's it going to be like when up upgrade the mobo and get PCI 3.0!

Maybe there's some kind of wait state setting that will help till then?

I'm sorry to disagree with you, but I certainly do get AA when I select the 'Enhance the application setting' option.

Look at my first two screenshots. I have disabled all of my AA settings in my NVIDIA Control Panel and you will see how the game looks with no AA.

The easiest place to note the 'jaggies' is the cockpit frame directly under the Emergency Exit sign. Also note the current frame rate (292).

Now look at the 3rd and 4th screenshots. I have enabled the AA settings and selected the 'Enhance the application setting' option (the option you said "...will get no antialiasing at all...").

The 'jaggies' from the 1st screenshot are now gone. This is proof that AA is working with the 'Enhance the application setting' option enabled.

Also, you can see that the frame rate has gone down to 265...further indication that AA has been applied.

Oh, yes, but thats just because you are using FXAA - which is a simple post calculation of every picture. It works whatever you choose.

However, it also blurres the dots (contacts), which makes them quite hard to notice. The game is old and not very suited for new technology. I suggest 8x Multisampling AA (or 16x if you like). It smoothes the edges very well but leaves the rest of the scene clear and sharp (i.e. the landscape). And it will give you better framerates as FXAA.
For Multisampling AA you will need 'Override any applications setting'.

For anisotropic filtering I suggest 'Application' as IL-2 comes with a build in mode, which works just fine (saved FPS!).

And you can disable the 'Transparency-Antialising'. It doesn't do anything valuable for this game and just sucks down your framerate. The same for 'Antialiasing-Gamma-Correction'.

Here is my setting (just in german):

BTW... you should change your signature then. ;)

I have the same card (EVGA GTX 650 Ti 1024) and had no problem running the 306 driver (am trying the 307.74 now) using the "override any app. setting" in the Antialiasing-Mode. I run 8x AA and Anisotropic and get no jaggies whatsoever. Only thing I havent upgraded is the Precision X program as the newest leave out some monitor display options that I like.

I also have the "power management mode" in the 3D settings but I have an AMD dual core CPU.
