Explosions deform the terrain or not?

In many places on the Web I read a game description (ex. http://springfiles.com/spring/games/zero-k-16 ), and important feature is Realistic Physics and "explosions deform the terrain".
I don't see in-game terrain deformation from explosions. It presents in the game or disabled?

also terrain deformations may not be visible if you're using an unsupported graphics card (such as intel/amd embedded cards). In that case it falls back to software rendering and you can hardly see any terrain detail at all.

You can see how hard some terrain is by holding space. Most maps are within the range of 100 to 200 hardness which makes the terrain changes significant after a few minutes of fighting in the area. Some maps are less than 100 so their pathability and cover will change with few shots. Some maps, like Comet Catcher, Red Comet and most metal texture maps have high hardness so are barely affected. Some maps, like Sandcastles, use varied terrain hardness depending on the look/intention of the terrain.

also, use F1-view to display height by a coloured mapping on the ground.
