[[File:Terrain texture scheme DDS 01-2000.jpg|800px|thumb|Comparison of texture in relation to the three possible choices in "Rendering Options" -> "Terrain texture scheme"]]The final result, with all the "Shader Options" active, is not very satisfactory, I would say very poor. Apparently not check on any improvement in the speed of image loading. I think on modern machines with quad-core processors 16 GB, with latest graphics cards (NVIDIA 870) 6 GB, the loading of these images is not really a "bottleneck". I propose to insert the DDS functionality, but in a transparent way, ie convert "on the fly" the images before inserting them into the temporary memory, for example using the convert function of ImageMagick. However, I do not know if it really is a useful feature, I think there are many other things to do before this.
