Terrain 6, 40km with 3.8 million objects
Technology demonstration terrain. Not a "real" terrain addon, randomly placed objects.
Large terrain of 4096 grid size, 10m cell size (comes to 40km x 40km) with 20480 x 20480 resolution satellite texture and 3.8 million objects (yes 3,800,000 objects).
Requirements: ArmA 2 Combined Operations, no addons needed.
Tutorial Terrain 6 - 40km
ArmA 2 Combined Operations (arma2 + operation arrowhead).
4096 grid, 10m cell size, 20480 resolution satellite, 3.8 million objects. Terrain size is 40km x 40km.
This is technology demonstration terrain showcasing that you can indeed have large and detailed terrain with many objects. Vegetation is randomly placed, the few cities are placed semi randomly too. This is pure random generated terrain and no human manual work has been done to the object placement at all (this is just a tech demo).
Development and test machine is AMD FX-4170 Quad-Core 4.2Ghz, 16gb ram, nVidia GeForce GTX560. Framerates are full / normal. In map view (M) you detect slight sluggishness and this is because the terrain is so rough with many elevation changes in short distances. Map view sluggishness could be avoided by making smoother terrain, but since this uses 10m cell size for details, it was nice to pump in some roughness.
