You cannot deactivate the High Resolution Terrain. If you no longer require that terrain you need to remove the HGT files from your device. On Android devices you need to navigate to the folder containing the HGT files and manually delete them. On IOS devices it is not possible to delete data files. You need to uninstall the SD application and then re-install it (remember to save routes, aircraft, settings, logs to the cloud first) George E A Reid Ipad Mini 5, IOS 14.4, SD 3.15.0.288 PC(Win 10, Version 19041.804) SD 3.15.0.0

Hello SD-Team, the map scroll speed is not very fast at my iPad4. So, i removed the high-resolution, deactivated the railroad-tracks. After that, the map rebuilding is nice fast. At my iPhone 6 Plus, everything is ok. Only the iPad4 :-(

Only the first time it is shown, the terrain is built; just the save as low-resolution terrain data. It is then cached and there's no difference in tile load speed between low-resolution and high-resolution.

Now, my old iPad is fast.
