looking for High rez global textures for FS9. Would like to replace the default textures with High rez ones especially the very ugly desert textures

Well a couple of things spring to mind. Firstly you need to learn some patience... secondly you need to post in the correct forum
Okay are you talking payware or freeware? On the freeware front I personally love Bill Lyons Silver Wings package http://www.simviation.com/fs2004scenery70.htm we also have a lot of other add-on textures in the scenery downloads. Best to have a look and see what you like. Just remember to back-up you original texture files
