* the LOD algorithm should be moved to a separate thread, otherwise it really will just drain on the main thread, and will have less, if not worse performance that is possible with a properly implemented LOD system. This may have some problems however due to the potential for the LOD system to have issues with the property tree and threading. | * the LOD algorithm should be moved to a separate thread, otherwise it really will just drain on the main thread, and will have less, if not worse performance that is possible with a properly implemented LOD system.

* It may be wise to base the LOD changes off of Rembrandt, rather than the current FGFS code base. Deferred rendering from Rembrandt is a major rendering change, and it may or may not play nice with a new LOD implementation based on the non-deferred rendering of the current code base. | * It may be wise to base the LOD changes off of Rembrandt, rather than the current FGFS code base.

* For higher end GPUs, implementing some of the techniques from these blog posts may help increase FPS on OpenGL 3 and 4 level hardware.
