NVIDIA 3D settings

Wondering if the 3D settings have any impact on the game or is it best just to use the in game graphics options?

 

Yes, they work. I use them to improve texture quality and add a bit of sharpness.

 

Could I ask what settings you use?

 

Anisotropic filtering: 16x
Texture quality: High quality (this will also set a couple of other settings accordingly)
Sharpness: 33% (I use it on top of 8x anti-aliasing setting in the game. Whether to use sharpening or not, and how much, is just a personal taste.)

In order to use sharpness filter, you need to turn on Picture scaling. This will also add a few additional lower resolutions to Windows, with the same ratio as your native one, but I don't use them, I run the game on native resolution.

The textures look much better this way.
