Feature Request: Configure renderer resolution

pandamicro · June 7, 2023, 3:48am

For screen back buffer, it’s possible to use root.resize to customize back buffer resolution, it affects the back buffer size.

Otherwise, I have proposed a feature request in our engine repo

github.com/cocos/cocos-engine

Add screen size and resolution APIs

### Use Case Screen size API is important for Desktop apps, and dynamic adjust …should be available at runtime. Passive screen resize now involves back buffer size, all cameras and re-adaptation of UI, but developers could also benefits from active screen resize APIs. On the other hand, even with constant screen size, developers can also have performance benefit if we allow user to customize its resolution. This is important on mobile devices and web. ### Problem Description Currently we only have [`root.resize`](https://docs.cocos.com/creator/3.7/api/en/class/Root?id=resize) API, but it's too low level, we need `Screen` level customization which could actively handle all relative changes. Request received form the forum too: https://discuss.cocos2d-x.org/t/feature-request-configure-renderer-resolution/58888 ### Proposed Solution Proposed APIs - Support `windowSize` for other desktop platforms in [screen](https://github.com/cocos/cocos-engine/blob/v3.7.4/cocos/core/platform/screen.ts#L81) - Add `resolutionScale` to [screen](https://github.com/cocos/cocos-engine/blob/v3.7.4/cocos/core/platform/screen.ts) ### How it works _No response_ ### Alternatives Considered Nothing to add ### Additional Information _No response_

Besides, in Cyberpunk demo, we have a resolution solution with custom render pipeline, so you can refer to this post for how it supports different resolution
