Obviously, there's more to it than just loading tiles into memory.For example here's an interesting quote by Ben Supnik on the subject of LODs:QuoteNot drawing an object is great for framerate. Not only do we save the time on the animations and attributes, but X-Plane never has to process the texture or geometry data, and that’s where the real framerate win comes from. Therefore the most important question for object LODs is “what is the maximum LOD” – that is, what is the farthest distance before X-Plane can stop drawing your object. X-Plane is pretty efficient at recognizing cases where objects, or even whole classes of objects, are simply too far away to draw.

Honestly, they cheat a bit, even with extended DSF. Buildings not all that far away are transparent, and only solidify as you get closer, and a good example of that is New York's Jfk, where the city itself, which is perfectly visible from there in real life, is invisible in X-plane until you are pretty darn close.Try flying from JFK in FSX, and the City is easily visible.

This is often the case with converted scenery and objects. Therefore it's really important how the objects are constructed and how their LOD levels are configured. And of course, it also depends on the rendering settings as they influence the dataref sim/private/controls/reno/LOD_bias_rat (among other things) - it's interesting to play with it in real time using dataref editor to see how the max LOD distance changes and how it influences FPS.
That's the Steam framerate counter right? Note that there is an option there to make the number green so you can see it better.
@Jagerbomber... what are your machine's specs? In particular your graphics card?On an overclocked I5 (4.4Ghz) and a GTX 660 TI I get about half that frame rate.I'm curious if an upgrade to a GTX 980 is worth it.Thanks.
