The overlay patch certainly allows higher resolutions. You're limited by your hardware though, as well as your photo source (it makes no sense to generate textures with a larger resolution than your source has). I'm using 16384*16384 textures in a project, but not all GPUs will support that. We also had to use the 64 bits version, because 32 ran out of memory after three tiles.
It's as simple as placing a larger resolution DDS file in the terrain directory.
The question is, what technique is sgb110 using?
