Celestia Forums

I put the 8k texture in Earth "Realistic-Earth8k.dds" and realized that the height of the mountains were not so accurate(the bump effect) as the 4k texture "earth-4k-BM-col-bmp-um.dds".Everything else is better with the 8k.
I wonder if it is because of having a 8k texture combined with a 4k Normal Map.Do anyone have an idea?
Anyway,I can?t put all the textures(surface,clouds,specular,bump) in 8k,because I have a GF 4 MX 440 and the Celestia loaded with this has a frame rate too low(10 fps or less)

try my EarthLOI .ctx and EarthNormal.ctx
and EarthSpec.png
the level 0 is 2k .png
level 1 2k.png
level 2 4k.png
and in a seporite file
the level 3 8k.png
I have the same vidio card as you and it works fine
