I did a test to find out what causes more lag game geometry or mapmodel geometry to do the test i made a mini city and I looked at the frames per second (Fps) then I converted the buildings of the city into mapmodels and put them in the same map and I looked at the Fps again. In the city with the buildings made of game geometry I got 6 Fps and in the city with the buildings made with mapmodels I got 11 Fps. So I figured out that is better to use mapmodels when possible when making big or detailed maps I hope this helps

I've seen this vid on youtube, I think it's because of the shadows and because of the fact that the models are just clipped in a huge box, while the geometry ones are clipped in the entire building, which could take your fps down, and I think your pc isn't that good (I get 150 fps while in such a map, and my pc really isn't that good), maybe you should upgrade it

The curious thing is that in the sandbox wiki in 'mapping taboos' it says this
Sanbox wiki wrote:Mapmodels are objects in your game. You should use them in moderation; don't overdo it, because their rendering process is more expensive than that of terrain. This results in higher polygon-per-scene counts.
So i guess that article is wrong acording to my test

Case in point: forest
If the trees were plain geometry that would be a cinch to render and calculate lightmaps for.
As you can see that is obviously not the case

The tree mmodels make me lag a bunch, so I generally avoid high amounts of mmodels and use geometry when possible.
