Orbx true earth great britain south bad fps in The Prepar3d Forum Posted March 9, 2019 58 minutes ago, Christopher Low said: You need to make sure that Aerosoft Heathrow is above ORBx TrueEarth GB South in the Scenery Library. As for poor performance....welcome to the club My (hopefully temporary) solution is to remove all of the "3DM" files in the FTX_EU_!GBS_05_SCENERY/Scenery folder (move them to a separate backup folder). This will remove all of the custom 3D apartment/warehouse/office buildings, but leave you with all the autogen buildings and trees, the bespoke POI 3D landmark models, and the beatifully colour corrected photoscenery. Frankly, it still looks fantastic in this mode, and light years ahead of any other scenery solution. With a bit of luck, the upcoming service pack (and control panel) will enable the vast majority of users to achieve a good compromise without having to remove most of those "3DM" files. EDIT: For the record, I only have a 2GB graphics card (GeForce GTX 770), so I will never be able to run it at maximum detail levels, even with optimisations. Nevertheless, I am hoping that I will be able to use at least some of those "3DM" buildings. Do you have FTX England - If so with the 3DM buildings disabled do you get around the same perf?
