• 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.

MSFS Drastic drop in performance with Enhanced Terrain Mesh (ETM) in SU9

Enhanched Terrain Mesh

After the MSFS2020 upgrade to SU8, there was a considerable increase in stuttering in Enhanced Terrain Mesh (ETM) with considerable degradation in flight quality (to put it mildly ... really crap). We concluded that this is due to MS / ASOBO changing the "way of how terraforming is processed has changed a little with SU8" as reported by Boris_ (MS / ASOBO Team).

So, I started to investigate both from the point of view of the hardware settings of my system and by replenishing with the newest MS SDK getting some small improvements but not enough.
To date (07 May), something has moved in the right direction since MS / ASOBO updated the two Apps that most have to do with MSFS2020 on MStore:
Xbox (vers. 2205.1000.17.0) and,
Gaming Services (vers. 3.65.3001.0)

I was pleased to note that now ETM which makes extensive use of Terraform with Heightmap is much improved and the stuttering problem has been significantly reduced.

So, I will shortly publish a new version of ETM12 Angola vol.01 which has been recompiled with the latest SDK 0.18.0, in the meantime I ask you for your impressions on the above after updating the two Apps (Xbox and Game Services ) to see the performance improvements
