the 3D framebuffer will be 3840×2160.
- SSAA can be used together with FXAA or TAA to counter the blurring added by
those algorithms, while further improving antialiasing quality.
- **Alpha antialiasing:** Applied on certain materials in the demo, available in
two modes (Alpha Edge Blend and Alpha Edge Clip). This is most effective when
MSAA is enabled, as Godot enables alpha-to-coverage rendering on the material
in this case. When MSAA is disabled, a fixed dithering pattern is applied on
the edge of transparent areas on the material.

Godot allows using multiple antialiasing techniques at the same time. This can
be useful to obtain the best possible quality, or to find a better performance
