The same 3D scene 3.8.3 takes up 90MB more memory than Unity 2021 about cocos-engine HOT 10 OPEN

Did you test in release mode?

from cocos-engine.

Did you test in release mode?

yes, build android release apk, code is here https://share.weiyun.com/14O8zNAF

from cocos-engine.

May be you can try to improve it by:

• use opengl es instead of vulkan
• disable multi-thread rendering in GFXDeviceManager.h
• don't trigger Allow Data Access if the mesh is a static mesh, which means the mesh will not be used again after sending data to GPU
• don't include modules that are not needed in your game

from cocos-engine.

Is there an official demo for performance comparison testing?

from cocos-engine.

No, we will not provide demoes for this type of comparison.

After disabling multithreading and taking the above measures, there is still about 60MB more, are there any other measures?

from cocos-engine.

Did you disable not needed features, such as physics.

from cocos-engine.

After disable not needed features， the memory is still 50MB larger than unity 2021

are there any other measures?

Hey, at least the CPU won! Double! 🤩

from cocos-engine.

Hahahaha That's a difficult trade-off.
