Understanding Camera.screenScale

[Migguli]

Hi.

I’ll start by saying thanks and good job with the 3.0.0!

So the Camera component has screenScale setter.
https://docs.cocos.com/creator/3.0/api/en/classes/component_camera.camera.html#screenscale

By setting this lower or larger I see no changes in rendering. Did I understand correctly that by changing the screenScale to lower I would get lower rendering resolution and therefore better performance?

The goal for me is to lower the resolution to improve performance in low-end mobile devices.

Thanks for any help

I got the response in discord. It is not possible yet to control screen buffer size to lower the resolution.

Not supported yet, in 3.1 or 3.2 we will probably have an offscreen render buffer, then it will be possible to downscale the resolution
Currently, the content is directly rendered to the on screen buffer which is exactly the physical resolution
