these lod textures look leaps and bounds better than quarls btw
They probably are qarls. There are various background enhancements you can use so its up to the user to customise the game as they see fit.
First you have simple higher res distance textures which is an area dominated by Qarl. Then you have a couple of non qarl options for better tiling of distance textures so that you don't see repeating patterns at a distance, however you would certainly want to use this in combination with the higher res distance textures.
Finally you have the qarl high res normal maps which you see in my screens and which give the impression of a much more "craggy" landscape. This is best used in combo with the mods above and personally I think it looks stunning but its certainly not a requirement if you prefer the smoother landscape look.
All of the above is merely for the distance textures though. The closer textures are dealt with by a completely different qarl mod called Texture Pack 3 (the successor to 2 and 1). This is a massive mod which replaces justr about all of the stock textures in the game (aside from distance textures) with far more detailed and high res versions. I personally think they are a universal win, better in every way than the stock textures. TP3 also adds extremely detailed parallax maps to many services significantly adding to the graphics detail.
