How can I get rid of these thick and pixelated outlines?

Question

As you can see in this screenshot, there are these thick black outlines all over the place:

I've attempted:

• Changing resolution
• Using fullscreen or windowed
• Upgrade FPS to maximum
• turn sync on
• turn up anisotropic filtering.

The issue continues regardless of these settings changes.

What's the cause and how can I change it?

Answer 1

The black outlines are part of the art style of Borderlands, most of what you see on your screenshot is intentional.

The only way to get rid of the pixelation is to enable antialiasing (FXAA option in the video menu).

I'd also recommend to use the lastest driver to deal with any graphical issues.

The outlines look a bit thinner on my computer, the following screenshot is with FXAA enabled:

Answer 2

In WillowEngine.ini, find this line:

DefaultPostProcessName=WillowEngineMaterials.WillowScenePostProcess

To turn off the shader, you need to make adjustments to the line — namely, remove both instances of the word “Willow,” so it looks like this:

DefaultPostProcessName=EngineMaterials.ScenePostProcess
