FS9 can't make use of 1024 ground textures, you're seeing the 256 mip level which is no different than default in terms of resolution. 1024 ground textures in FS9 serves no purpose, it just consumes unnecessary disk space, and if they're not mipped they won't show up at all. Further, the autogen will be a mess if doesn't match the textures, you'll have forests showing up in fields, houses in water, etc.and FSX autogen won't work in FS9 - it's a completely different format. BTW where are you getting 2048 or 4096 textures from FSX? Freeware FSX scenery files. Converted to 1024 x 256 colours down-sized from either 2048 or 4096.

Because of the higher resolution to start with, they look far better and sharper then default when reduced. Seen some guys do it with the high res REX clouds so I tried it with ground textures. Also a certain replacement texture set has been done for fs9. Grabcevich sbornik zadachi po fizike dinamika reshebnik.

Looking at some clips and screenshots, far superior to what I've got with GePro including city areas which look like FSX resolution. So I reckon it can be done. Has been done. Admittedly, up close - down low - not so great. Up higher.fantastic!
