With 64MB should be able to use 16k DDS textures with no problems.

I'm using a GF2 card in my system... I can use Don Edwards 16k quite easily....

I'm waiting to download the latest drivers.

OK,but the problem is that I have 2 k texture in Jupiter,Moon,Mars and Earth and still my frame rate is around 20-30 fps or less.In the nebulas,the framerate is around 60 fps,and in Jupiter too.
I was with 4 k texture in Io and Moon,2K texture in Earth and its clouds,2k texture in Europa,2 extrasolar planets textures,extra texture in Sun,and 8 nebulas.I was with 10-15 fps or less if I approach a 4 k texture or even Earth and Moon together.
Well,I have toggle video properties for Quincuxx AA e 2XAF.Do someone can help me?What?s wrong?

I have found that 4k .png are about my limit befor the frame rate become to slow
Earth
4kEarth.png
4kEarthNormal.png
4kEarthClouds.png

but the best compramise for detail/speed is
8kEarth.dds
4kEarthNormal.png or 8k but it is slow
2kx2kEarthClouds.dds

and my box is win Xp 512 sd ram and a 64MB nvidia gforce2 mx400 and
6.14.10.4403(44.03) driver
