Please point me in the right way to re-size .dds files. I want to make some smaller due to not having the best rig. Can they be changed to DXT3 and used in FSX. Any help would be appreciated. I did Google and check the forums here first. Thank you.

The answers are yes and yes (I just tried it...!). Any graphics application that will allow you to resize (I use Photoshop) can be used. I suggest 1024x1024 is minimum for a clean .dds main texture file. Then you can use Martin Wright's dxtbmp programme to convert to DXT3.
Best of luck

I use "texconv.exe" and a small batch file to resize my textures. It is fast and iterative. I simply drag & drop
the 2 files into a texture folder and run the batch file. I actually have different batch files for the various types
of dds files and run the applicable BAT(s) based upon the types and name convention used.
As an example:
This sets 1024 x 1024 and adds mipmaps
@echo off
cls
texconv -w 1024 -h 1024 -m 8 -f DXT5 *_t.dds
This one is for the specular files
@echo off
cls
texconv -w 1024 -h 1024 -m 1 -f DXT5 *spec.dds
This one reesizes the _t.dds files
@echo off
cls
texconv -w 1024 -h 1024 -m 1 -f DXT5 *_t.dds

Thank you for the info. I will give them a try.

Just note that not all image conversion software is equal. Reducing size means reducing the info content, and there are a number of algorithms to do that. From what I've seen most programs will default to the fastest method, which is probably also the lowest quality. Without analysis, I typically use Lanczos algorithm if available in the program.
Also for FSX I believe DXT5 is preferred over DXT3.
