    To me it has now also become clear that systematically decreasing scenery texture sizes only has minimal effects on scenery loading times and/or frame rates but this could also be influenced by the fact that my machine is fully equipted with SSDs instead of HDs.

    I guess I can sweep all my own FS9 improvement activities under three combined words: "Technical", "Hobbyism" and "Collectorism", which I think could be rather logical after years of "armchair" FS9 flying and covid lockdowns.

    Mallcott suggests decreasing the number of my scenery layers but to me as a collector this would be like sinning against myself or even like swearing in a church !! Moreover, my FS9 makes intensive use of library objects, which makes deleting any of my sceneries extremely unpredictable for remaining sceneries.

    Anyway, I've learned much from this whole "issue" and from all the reactions in this thread.

    Cheers.

    Hans, a still convinced FS9 diehard.

    P.S. "If it aint broke then don't fix it", but just as true, "If it aint broke then don't ...LET ... it be fixed", e.g. via Windows updates and it remains my opinion that the basic Win7 is still the most efficient platform for FS9, whatever it's size.
    You can't fly 1,000 sceneries no matter how short your flights. Consider separating and combining the one's you DO use. Delete the rest.

    Having tons of scenery shouldn’t add much in the way of loading times unless you have basic hardware running your machine.
    I found deleting vatsim / ICAO ai if you have any, or unused ai the biggest difference to loading times for me.

    Although 1024 x 1024 32 bit textures at airports with a GPU using high SGSS etc doesn’t help either.

    So loading times as in textures loading? Poor FPS? Stutters? Pauses? Freezes? Lockups? CTD’s? BSOD’s? (<all jokes aside, honestly who gets these anymore? ).

    Hi Guys,

    Further testing has now revealed that decreasing scenery texture sizes in batch mode or even individually, can disrupt the way in which their related BGL files handles them. So, for me it's end of story, simply because the results can be so unpredictable.

    Regards

    Now revealed? I’ve been doing this for a long time with zero issues. Depending on hardware I’ve hard that maybe isn’t up to scratch.
    Some scenery - airports - just suck the fps away. But I find I gain more by switching of ground shadows and or removing static objects, aircraft, trucks/cars or trees etc.

    Usually I gain some back that way.

    I still don’t get what you’re trying to do and why. I know you said earlier why on this but is it a problem at all airports, or just some?
    What hardware do you have?

    Loading times can be reduced by unchecking scenery layers you are not using at the moment. When traveling to another part of the world, just re-check those areas.

    Aircraft selection time can be reduced by moving planes you are not using into a Removed folder created inside the Aircraft folder. You can bring them back any time. Don't forget some planes are being used as AI traffic, though.

    Hi.

    I think the load times Hans referred to are texture and scenery object load times, not the application launch time.

    Thinking about Tom and Mark's suggestion concerning cleaning up scenery layers, and on the assumption that FS9 searches for scenery object textures in the local folder, then the root folder then all other folders, you might see an improvement if you run "find_all_duplicate_v2.4.zip" over at avsim, and put all your textures in /FS2004/Textures. You would keep any conflicting duplicates (same name but different image) in the scenery layer's local folder. The app doesn't delete duplicates, just moves them to a sub-folder.

    I haven't tried this arrangement but it obviously works for generic textures and for scenery object libraries. Does anyone know if it works? Or causes problems?

    If you haven't experimented, you could also try changing values of TextureMaxLoad and TextureBandwidthMult in fs9.cfg
