See if Bullet Physics' seemingly low scalability ceiling is due to all our physics objects being constructed from compound shapes. #670

Aether seems to handle this just fine, but maybe Bullet physics usage needs to be special-cased to use non-compound shapes where possible in order to address potential scalability issues.

Maybe using an bullet accelerator for the height map body would also help?

And Bullet also seems to offer parallelization as well, tho I don't know how to tap into that yet...

According to this, BvhTriangleMeshShape can perform better - https://pybullet.org/Bullet/phpBB3/viewtopic.php?p=36404&hilit=compound+shape+slow#p36404

But this forum is so full of shit sometimes, you never know what is true.

This might confirm my hypothesis - https://pybullet.org/Bullet/phpBB3/viewtopic.php?p=12670#p12670

Didn't investigate, but did make a work around where compound shapes are eliminated where not needed.
