What a difference has you can tell with a setting of 1 top pic the tiling is not so obivious and texture has almost the same amount of detail compared to orignial setting of 2 bottom pic.
Threre are still some tiling, but, has brumbek stated the textures have to be fixed in order to get of full tiling effect. This is good workaround till next ATP comes out. I say. At least with larger texture that is. And only landscape textures are affected, it does not affect anything else I have noticed..
