• 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.

Performance Problems

Hi,

we experienced that the frame rate of Prepar3D (2.2.10437.0) runs low after some hours of usage.
In the attachment you see an excel plot. We logged the frame rate every 4 seconds. The fps in Prepar3D was roofed at 40fps. After about 6h the frame rate dropped significantly below 40 fps.

What are we doing? Well we do nothing more then letting the own entity (id 0) fly in a circle of about 100km radius controlled via SimConnect. After the weekend the frame rate dropped below 4fps with 4 of 8 CPU cores running at 100%. On screen you can see that Prepar3D has a hard time to page in any new data showing terrain textures with very low resolution.

So it appears to me that Prepar has some paging issues that somehow cost a lot of CPU time.
Trying now to reproduce it in slew mode without SimConnect.

Thanks for any advice that helps keeping performance up.

Fortunately it's not reproduce able in slew mode and of course it would have been a surprise.

Im not in the office the next three days but than I will try to reduce my SW wich is using Simconnect to a minimum and run it again.
