Renderers

Introduction

Deft comes with the following 3 renderers.

Name	Description	Support Platforms
SoftBuffer	CPU rendering	Windows/MacOS/Linux
GL	GPU rendering	Windows/MacOS/Linux/Android
SoftGL	CPU rendering, GPU presentation	Windows/MacOS/Linux/Android

Usually, GL renderer has better performance, but consumes more memory, and SoftGL is suitable for scenarios where SoftBuffer is not supported but still want to use CPU rendering.

By default, Deft will automatically match a renderer based on the order in the table. If you want to change the default matching order, you can set it as follows.

1. Create a window and specify the preferredRenderers parameter, for example:

    const window = new Window({
        // prioritize use GL renderers
        preferredRenderers: ["GL", "SoftBuffer"]
    });

2. Set the DEFT_RENDERERS environment variable, which will take effect for all Deft applications, for example:

   export DEFT_RENDERERS=GL,SoftBuffer
