• 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.

MCX performance optimizations

Lately it has been quiet with new features for ModelConverterX, but that doesn’t mean I have not been busy. After optimizing the import performance of glTF files for MSFS, I found quite a big inefficiency in the way ModelConverterX stores the model data internally. So I have been working on optimizing that internal structure of the last weeks.

The performance gains of it turn out to be quite big. As memory, CPU and GPU usage can be reduced a lot. The screenshot below compares the current build I have in development with the 1.4 stable release. In both cases I have loaded the default FSX Boeing 747-400 model. As you can see memory usage is more than half (and if you remember textures take the same amount of memory the gain in the part I optimized is even more). Also the model pans and rotates also more smoothly due to the optimizations.

I still need to do more testing to make sure I did not break functionality, as it was quite a fundamental change deep inside ModelConverterX. So it might take a little while before I can put this out to the community, but something is coming your way soon.

Arno, thank you for doing so much work to improve MCX, I use the 9 Dec dev version and that already runs better than the one I used a few month ago.

These improvements have not yet been released, but that should give a much better experience.
