But there’s no problem with LOD nodes per-se, they just need to be high up in the tree, switching large amounts of stuff, eg a complete tile, not one window on the front door of a house :) And OSG LOD nodes can use distance or screen-space pixel metrics, and they update per frame, so you could absolutely increase the visibility, but reduce the detail levels, with increasing altitude; turning off trees, OSM buildings, and then /all/ objects.  <ref>https://sourceforge.net/p/flightgear/mailman/message/37129429/</ref>

|details=One issue is if people are connecting FG to a 2k-4k monitor with a marginal GPU. Such a monitor might be fine for text or 2d digital art, but run into problems in 3d. A way to avoid this would be to force 1080p by default with a message that theri GPU may struggle with the native LCD resolution - and an explanation flightgear can use GPU power to create interesting detail and content or render more of the same (boring) pixels.
 
Another issue is turning up settings like tree density for a GPU that's in a system with a a slower processor or maybe not much RAM. NVIDIA 10 series and newer use drastically less power - so they can be installed on much older systems sometimes without a power connector. Laptops use desktop GPUs from the 10 series onward, so they may come with less RAM. The LoDs also need to be definitely default, as a high rough LoD can increase RAM usage. RAM/VRAM usage by trees (and instanced shader buildings) can be reduced a hugely by using UBOs if UBO support is added in future - the current method stores copies of the full instancing data as vertex attributes for each vertex.
 
Currently the RAM and CPU stats are not available in the GPU profile system <ref>https://sourceforge.net/p/flightgear/mailman/message/37129612/</ref>
