• 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.

Optimize the scenery to avoid FPS drop

I have a built scenery and near to one block of a building, the FPS are getting hit for some users. I have used 4096x4096 textures for the block. Any tips on how to optimize further?? Should I downgrade the pixels to 1024 ?

Would be appreciated.
 
Optimization is a combination of things not just the raw pixel size of the original texture. Using the statistics profiler and LOD debug overlay in the scenery editor will give you an idea of how many drawcalls, polygons etc are being displayed at each LOD level as you move around the scenery, anything showing up as red in the lod debug should be looked at as it likely has too many tris or drawcalls for its screen size. Ways to reduce drawcalls are to pack more objects onto one texture sheet and join the nodes together prior to export. Of course reducing geometry complexity and reducing overall texture size helps as well. Also ensure you're using the highest compression possible for various texture types, here are the ones I use:

Texture File Formats

ALBEDO (non-transparent) - .DDS- BC1 (Linear, DXT1)
ALBEDO (Transparent/Blurred/Alpha mask) - .DDS- BC3 (Linear, DXT5)
NORMAL - .DDS- BC5 (Linear, Signed)
COMP & Decals (non-transparent) - .DDS- BC1 (Linear, DXT1) *COMP maps always have any alpha channel present stripped by the sim*
Decals (transparent) - .DDS- BC3 (Linear, DXT5)
