He's been very kind to explain what made the most difference performance-wise and what were the bottlenecks. The main remaining one in Godot 3 seems to be the physics engine that isn't fully multi-threaded. Camille, the physics engine maintainer, has been working on that for Godot 4 which should bring more reliable, much more intuitive, and faster physics.

Best thing about Godot is open instantly.

It's worth mentioning that one shouldn't just go convert existing code with this method. It doesn't account to a few things: The objects are still physically present. If you have any logic that uses the tree, like getting a node's children, or collision checks, those will still be detected. Not being visible and having disabled process loop still doesn't mean the game just disregards them. Unlike visible, set_process also doesn't carry to children. I had some unexpected behavior because other objects could still interact with them. So there's a lesson that if you're having a different "object destruction" behavior, it's also up to you to ensure they are actually gone.

I feel like I'm missing something here - The steps to improve performance make sense completely but at the end you are mentioning to just hide the bullets and just disable processing. Isn't that a memory leak or is this combined with the pooling so that the existing bullet is reused and made visible when needed (resetting position and motion vector)?

Oh my god, I've assumed this whole time that directly accessing the physics server was some kind of inefficient hack only to be used when the collision nodes wouldn't suffice, even though I find it more convenient half the time anyway. This video might... inform a few changes in my code, to say the least.

OMG, YES!
For me, main issue with using physics servers was to determine how exactly I should handle the collisions. And now there are you and Samuele. Thanks a lot! You brought back the joy and desire to experiment with Godot again! Now it's only left to find some free time ^^

I was trying to make a rts game with godot and found out that the default setting with rigidbody2D is costly. The fps will significantly drop as more than 150 rigidbodies move and keep detecting collisions. Now I know godot has low level servers to deal with it. Thank you!

i was planning to make a serious game project in the mono version just for the performance of c#
but now i'm convinced that GDScript is more than enough

[indieology]

Loving these daily videos! And really excited to start your course! :)

[adsick_ua]

0:40 why use circular collision when point is more than enough

[Ngong]

2:05 I wonder why removing node(s) when the condition met will be less performant than just make node(s) not visible and stop processing?

[josephbrandenburg]

2:56 what is this beautiful star fox clone?

[bceng]

What about in 3D? geometry is more complex and motion and physics is too.

[alfiansdump]

Does this only apply to static bullet? What about homing missile, or bullet that is able to chase the target?

[greg]

This is very impressive. I didn't expect this can be done.

[ariton]

Could you do a more advanced physics server tutorial? I dont know how to use it myself.

[jamesodonnell]

Holy pupu there batman you just saved me a lifetimes worth of frames with that little trick!

[ZeoWorks]

Keeping the nodes within the scene sounds like a bad idea, I imagine this would affect memory over time.

[Ainigma]

What's the game called at 2:58? It looks like star fox, very cool!

[blackcitadel]

8k bullets at the same time at 60fps using GD Script? That's impressive ngl.
