• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

FSX DDS vs BMP

Hi guy & gals, :wave:

I recently bought a couple of payware aircraft from different companies, one of which has the textures save as dxt5 bmp rather than dds, the other has a mixture of bmp and dds (the diffuse colour is dds, & the spec and bumps are bmp. All save as dxt5).

I always thought dds was the prefered format for FSX native models so I was wondering why the developer chose to use bmp instead.

I've done a couple of repaints & saved them as dds and they work fine.

Not a problem, just wondering :)
 
Hi,

DDS is indeed the preferred format, but FSX will automatically look for the same texture as BMP as well. If both are DXT5 I also don't expect much difference in performance.
 
Hi,
I think FSX works strange sometimes ;)
Even if your model calls a bmp texture, FSX won't search it first.
1/ fsx first searches a DDS file inside a texture.cab file.
2/ if not then looks for the DDS in a /texture folder.
3/ if not then makes a new search for a BMP file in /texture folder.
May be a reason why a drawcall is frame consumer ?
