Since we know that LOD increases are based on area, ie twice the lod is sqrt(2) times to draw distance. And now we know LOD distance seems tied to latitude (cosine latitude)
Alaska at 63 degrees, factor 0.45 (cosine) (Dunno where the Bush trip is, just taking a value in Alaska)
Patagonia at -47 degrees, factor 0.68 (cosine)
Thus draw distance would be 1.51x longer in Patagonia
Which corresponds to an increase of 2.28x in Terrain detail (LOD factor)
If all the ‘math’ works out (and terrain squares were equal which they are not) terrain detail 88 in Patagonia should look and perform the same as terrain detail 200 in Alaska.
