Default NVIDIA 3D Settings For IL-2

Maybe we can use this thread to discuss our Nvidia 3D settings for IL-2.

I'll start with an interesting one...'Antialiasing - Transparency'. In the Nvidia Control Panel the description for this Feature reads as follows: Allows you to minimize the visible aliasing on the edges of images with transparent textures.

Settings for this Feature consist of several Multisample and Supersample options. For this particular example, we will be using the 2x (supersample) option.

*Be aware that the scenes below already have 4x Antialiasing enabled. The 'Antialiasing - Transparency' Feature is a seperate setting.

As we all know, the 'jaggies' along the IL-2 riverbanks can be quite ugly. The first screenshot on the left shows an example of these 'jaggies' with 'Antialiasing - Transparency' turned OFF.

The second screenshot shows the effects of 'Antialiasing - Transparency' with the 2x (supersampling) option enabled.

In my opinion, the actual in-game improvement is better than indicated in the screenshot. Discussing the frame-rate hit, it seems to be fairly minimal. As you can see, it is 11 FPS for this particular example, which is about a 5% overall hit. There are additional 4x and 8x options for this setting, but they will obviously result in a greater frame-rate hit.

For instance, I get 175 FPS with the 4x option. This is a -32 frame rate hit compared to the OFF option. This is about a 15% overall hit to the test mission. However, this seems to remove just about all of the riverbank 'jaggies' and the terrain looks beautiful. (This is with the additional 4x Antialiasing enabled.)

**Be aware that your other 3D settings as well as your IL-2 Video settings may very well affect your final results. For this particular example I was using the 'anisotropic' option for the IL-2 'Texture mipmap filter' feature. Also, I was using the 'None' option for the 'Texture Compression' feature.

***Additional Info:

-Video drivers used for this test: NVIDIA ForceWare 320.18
-IL-2 version 4.11.1 (stock)
