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 and P3D v1.4 are limited, P3D v2.x is not.

FSX (with SP2 at least, this may be different for original FSX or SP1, I've only ever used SP2) can handle models with more than 65535 triangles.
FSX cannot handle a mesh with more than 65535 triangles that calls a single texture.
You may get this error in that case:
ERROR: Vertex list has too many vertices (372608), max allowed: 65535
ERROR: Attempting to add an invalid vertex buffer!
It can be solved by making sure that you don't have a single texture being used too much.
P3D can handle those sort of texture calls as it uses more bits to store the vertex buffer (32 bit I think versus the 16 bit that FSX uses)

Clone the over-used texture, change some of its settings very mildly, and assign it to half the parts used on the original texture. Texture meaning 'Material' in Max, same bitmap or PSD, two different Materials.
I have made models at 1/2 million polygons perfectly fine with the P3D V1.4 SDK.

Sorry for not clarifying that statement. FS9 is limited by poly count where FSX is limited by vertex draw calls when compiling. As stated below there are work arounds.

We have found that high polygon count planes run fine in FS. Textures however, that are quite large, like 4096, pull down FPS. Even on older computers, 2048 size textures can really bring down frame rates. But, poly counts, high poly models, tend to be fine in FS, even in old FS2004. I had a 1/2 million polygon test plane in FS9 and it ran unusually well, very smooth. Textures are the culprit.
Also, if you have sloppy gauge coding in your gauges, your frame rates will greatly drop.
