Unity Game Objects vs Entities: performance benchmark

[@CodeMonkeyUnity]

Really nice demo, love the sound effects!

[@VisualDecomplicator]

Really appreciate that! You inspired me to make this youtube channel (even to move to Portugal 😄hello from Madeira)

[@VisualDecomplicator]

Do you mean deadly efficient? Or coding in Unity Entities like cracking-your-brains? 😄

[@JacksonAcademy1]

@@VisualDecomplicator Yeah cracking your brains, It's like re-learning C# because the methods are so complicated. But it's worth it with performance.

[@surplusking2425]

@@JacksonAcademy1 Rather use Godot C++ or Unreal than those overly-complicated ECS crap.

[@SiegfriedTheCatfish]

@@JacksonAcademy1 Depends on the Project.People act like this is now the only way often, which it isnt.Thousands of bigs games are made without it, its only worth for hypercasual mobile games where you actually need to update 10000 of objects

[@JacksonAcademy1]

​@@SiegfriedTheCatfish I agree! also If you're making a hypercasual game, most likely you won't even have 10000s of objects.

Minecraft, but all the blocks are alive. Every time you "harvest" a block, it could squirt blood and make a tiny scream. Nothing stays where you put it because all the blocks move.

Very interesting demonstration, I've been doing similar benchmarks for a game I'm working on and the results are just as chocking !! The main issue I had with this kind of testing is that rendering starts to have a noticable impact on performance over 100k cubes and I found that the improvements are easier to compare when looking at the execution time of the systems instead of the fps.

[@reessimmons2159]

Great video! So clearly shows the performance impacts in a way that is meaningful to developers.

[@gunnarthoreson2280]

Very cool, its great to see the comparison visually. Also nice to have the code here to play around with it. I would suggest to also at a license to the repo, like for example MIT. Looking forward to your upcoming videos, keep it up man ✌

[@thenoxer9841]

This was actually really interesting

[@svendpai]

great demonstration!

[@TrentSterling]

Well dang, looks like its time to switch to ECS

[@dertobbe1176]

1 million is crazy

[@regys9521]

Insane!!!

[@GazziFX]

You can optimize your GO code to perform same as ECS, just code same systems with structs

[@mehmeh8883]

Interesting, just replace stuff with struts?

[@martingrof1685]

Yes dude just use structs, thats all ecs and cpu optimization is. lol

[@martingrof1685]

@@mehmeh8883 No lol

[@GazziFX]

@@martingrof1685 there was a coding video with performance comparison on youtube, but cant find it

[@DanielKierkegaardAndersen]

On systems you btw only need to add it to the OnCreate, OnUpdate etc. methods as they are 6 Special methods in systems that allow burst without being static methods. Aka, you do not need the system itself to have burstcompile. The only case where burst goes on a struct is on jobs :D

[@VisualDecomplicator]

You are right, thanx

[@DanielKierkegaardAndersen]

@@VisualDecomplicator I hope so, I did implement that part of the feature lol xD

[@v_e_l_d]

Issue is that you've used vertical synchronization, which is not good for framerate benchmarks. You should remove it next time.

[@fleity]

I mean yes in this laboratory level example obviously ecs is far superior. It's kind of an ideal scenario for it. The question is when do people need that many similar behaving objects. I see great potential in ecs for rendering and transforms in general but for gameplay logic.. Its only rarely as useful as shown here (might still be better than GO, granted but more complex too)

[@YeyMuffinsYey]

Purely on project scalability wise I'd take ECS even if it had worse performance. You can add systems on top of another and the de-coupled architecture really pay dividends in the early-mid to long term

[@martingrof1685]

Any game with multiple npcs or objects? lmfao

[@Rogueixpresents]

great but whats the ram/cpu usage, these counts also have impact on the ram/cpu no? what are there? :O

[@nand3kudasai]

nice comparison, but too synthetic. the logic on each object is really simple. the amount of things also very limited. they don't even have collision. if you want perf you could have implemented the same with a particle system.
