iniBuilds has done some good work on Dubrovnik, good detail throughout with a nice integration into the surrounding landscape. The custom approach lights structure at the slope is done very well and greatly enhances the immersion of landing at LDDU.
Unfortunately the runway textures themselves are not very realistic, the rubber/tyre marks have a very 'digital' feel to them in terms of how they are added on top of the runway surface.
Something that needs urgent attention by ini is the LOD for the main terminal building. There is massive LOD changes at close distance when approaching the terminal, they are very visible and rather bad for the immersion. I hope this gets optimised soon!
Other than that, well done, go get it if you need a good Dubrovnik.
