How to control Terrain Texture Blur at Distance (pics)

My terrain texture switches to a low resolution texture when a certain distance from the camera. It does so in large square blocks (not per pixel).

Here you can see the issue:

Half of the city is high res, while the other half a little further away is very blurry.

If I move the camera forward a few meters forward, the city texture pops back to high resolution (although if you look closely the textures around it are still blurry).

Is it possible to control how aggressive the texture LOD is? We are a flight sim, so textures should be quite distant before switching to low LOD.

Looks like the Terrain.basemapDistance setting.

You should be able to change it via the Terrain menu or via code.
