To re-iterate - GPU VRAM is a precious commodity, so we should spend it on
texels you can actually see.

Also the question to GPU gurus: I think most aircrafts that have hi-res
liveries do so because of several small signs here and there. So does it
makes sense to have a lo-res opaque texture that paints aircraft's body,

Full GPU memory leads to performance deterioration.
Well, I'm not entirely convinced that plus-munis some tens of MBs made a
difference in one case I heard of (tu154b, five 1024x1024 textures for the
exterior). Yet I'm convinced that mipmap alone

skeletal systems for example.

Why limit yourself to only one downscale level? Mipmap can go several
levels down, so it doesn't make much difference whether you started 4096 or
2048 (leaving space issues aside).
I suppose mipmaps aren't used for liveries in FG. What would be the cost
to do so? It doesn't sound right that

Ah, I see your point now, sorry. Still, crunching 256x256 texture to
produce a 10-pixel image of a plane at a distance is surely a lot better
than crunching original 4096x4096.

On second thought I'm starting to have doubts about what you are saying
being true. I thought that the engine chooses right mipmap size based on
the estimate of the dimensions of the resulting screen projection. And if
it works like you describe than there should be some absolute scale for all

OK, I see what you're getting at now-- the selection of the mipmap for
rendering rather than the memory footprint. Yes, that makes sense to
me-- the engine should be able to
But high res liveries already there, so the choice is between using more
memory or having low fps. I think the choice should be obvious: if you do
have spare memory, not using it doesn't make you any good.
Quite recently there was a discussion about 2048x2048 textures for scenery,
and I'm sure
