• 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.

FSXA Direct X 10 compatible development

Hello,

This is a basic question that torments me in recent weeks.

How to ensure that when developing an aircraft for Flight Simulator X, it is 100% compatible Direct X 10. Or, conversely, be sure it is operating "solely" on Direct X 9. To add no portability is desired that it be on FS9 or Prepar3D.

So, is it just the use of such parameter in textures or materials? It goes further?

The subject is open :)

I'm hoping with this subject to have the tips to know the feature between 9 and Direct X for Flight Simulator X.

In addition to the search parameters on the forum and it was impossible for me to see if a topic has already been opened. In advance I apologize.

Thank you

David
 
Hi David,

I would say the best way to make sure is to follow the FSX SDK to the letter.

But on the other hand the question is a bit irrelevant, the DX10 mode in FSX is flawed, so hardly anybody uses it.
 
The big problem with so-called DX10 development is that you can use the SP2 SDK (Microsoft's own latest tools) and still get unpredictable results.

There are some users who remain staunchly under the misapprehension that developers aren't making things "DX10 compatible" but the reality is that, short of stripping out the things that don't work in DX10 there is no set of tools or processes that makes something DX10 compatible.

If you don't use any advanced material parameters (specular / reflection), and minimal fx, and no FS8 (groundpoly) surfaces then your scenery/addon will be fully DX10 "compatible"

.... unfortunately it may also be extremely boring.
 
I don't think the tool support is lacking, the dx10 mode in the sim is just buggy.

You are correct, of course, Arno.

Unfortunately purchasers of scenery add-ons don't seem to understand this.

They will often tout benefits related to DX10 in terms of smoothness or water rendering, but will not accept that the coding was never completed / fixed.
 
Concerning airplanes, I work in creating pure FSX format planes and with several of my many releases, even with pure FSX SDK tools, the planes will malfunction in DX10 mode (not all) by showing one to several materials in 'FSX' textures (having FSX flight simulator written on the parts).

A very odd thing....


There is a large group of people that like to run DX10 and run into bugs with models. They get pretty upset, but its like, we compile our planes in FSX format and it has all DDS textures and things. Why its not working right is beyond me.

Wow thank you all for your feedback ;)

Sorry for my late reply, busy at work these days.

I therefore understood that FSX can not function entirely on DirectX 10 (it has not been programmed to). And that the DX10 mode is buggy.

I just follow all steps present in the SDK documentation to develop my plane work perfectly in DX9 mode and "simulated" of DX10.

There are also chances that the SDK tools risk of not doing their job.

So, I must not break my head with the DX10 mode to do well :)
 
Yes Dan,

8 months on and Steve's patches have been released and fixed a great many DX10 problems.

All of them? Last time I looked night textures on ASM coded groundpolygons still didn't work, but I haven't investigated since.

Amusingly, now that the original problems have been fixed (by fixing the engine, as we have been saying was required) there is still an expectation that any residual problems are due to the scenery!

It would be fair to say that DX10 has been fixed to the point where it is usable for 'most' users, however. That seems to be quite an achievement.
