Enabling mipmapping significantly reduced texture aliasing at a distance in the game.

The game engine generated mipmaps for each texture to improve rendering performance at different distances.

The game engine performed better when all textures were mipmapped to reduce aliasing and improve performance.

To reduce shimmering and improve performance on distant surfaces, the artist generated a mipmap for each high-resolution texture.

Before the mobile build, I asked the asset manager to mipmap the terrain textures so they would scale smoothly across different devices.
