No because that would be unnecessary computation, but a fast calculation on the physics and collisions will be done so its is save to say “the tree fell” because we can observe the results of said fall

Thats render permanence. The reference to the object is still there in the level layout and its properties are still there in the object array.

Not sure that’s the reason but there is a Russian version of lord of the rings where sauron is the good guy fighting for the rights and freedoms of the working class orcs against the fashist rule if the elves and Gandalf.

There is also a light novel about Putin (or maybe Stalin?) being teleported to middle earth with a few guns/tanks and helps sauron win.

So yeah Russian propaganda sympathises with orcs
