Use of mipmapping only mitigates the issue. If a very high resolution 4096x4096 texture is being used, the first level of mipmapped texture reduction is 1/4 of that in pixel area, or 2048x2048. If a texture of more modest resolution like 1024x1024 is used, then the first level of mipmap reduction would result in a 512x512 texture. So a high resolution base texture is still going to result in a larger mipmap texture than a lower resolution base texture at the same mipmap reduction level. This is true of any texture in the scene where the object is not culled by LOD settings, etc. Liveries just tend to be the biggest hits. The results are cumulative for your video hardware. So in multiplayer, all those additional aircraft in the scene using high-resolution textures will tax your video card more heavily than aircraft using lower resolution images, even with mipmapping enabled.
