Should you like to design your own property here are the specifications that are mandatory.

Polygons

• Private plots maximum 1200 (but less is very much encouraged)
• Commercial ones maximum 2500 (but less is very much encouraged)
  Textures
  
• The objects should be cleanly unwrapped and there should be as few UV vertices free after the process. Unify where you can.
• Size (pixels) and depth (Alpha channels) should be kept as limited as possible. Use symmetries to map same space again to save overall texture space.
• The total numbers of shaders (materials) in the scenery should be as low as possible.

The best possible performance could be reached, when you have

- One Model (MDL)

- using one Material

- placed with one Scenery Object XML Placement

In this case, the poly count is secondary (as long as you don't get into the upper 10.000th)

Increase the poly count from 1000 to 10.000 will effect the time needed maybe in a low % Area

Increase by one off the above part (two MDLs/Placements or two Materials) will double the time the engine needs to render the objects, so 100% more in render time.

Good comments.
