No, I read it right. I was saying that I was about to explain why, but my explanation turned out to be incorrect, to my surprise.

However, they say:

> That said, Godot 4.0 introduces the ability to bind custom physics engines at runtime (without recompiling Godot) via GDExtension, so it’s perfectly possible for the community to integrate other engines such as PhysX, Jolt, or Box2D if need to be.

I'm liking this work on GDExtension. It'll make Godot a lot more capable just on its own.

But they are only mentioning PhysX as a reference for a high quality phsyics engine.

The only tried to integrate Bullet.

Isn't PhysX hardware accelerated only with CUDA? In that case it would make sense for Godot to avoid it even if it's open source, becasue it's targeted for Nvidia.
