If set to a value greater than [code]0.0[/code], contrast-adaptive sharpening will be applied to the 3D viewport. This has a low performance cost and can be used to recover some of the sharpness lost from using FXAA. Values around [code]0.5[/code] generally give the best results. See also [member rendering/quality/filters/use_fxaa].

If [code]true[/code], uses a fast post-processing filter to make banding significantly less visible. In some cases, debanding may introduce a slightly noticeable dithering pattern. It's recommended to enable debanding only when actually needed since the dithering pattern will make lossless-compressed screenshots larger.

[b]Note:[/b] There are known issues with debanding breaking rendering on mobile platforms. Due to this, it is recommended to leave this option disabled when targeting mobile platforms.
[b]Note:[/b] This property is only read when the project starts. To set debanding at run-time, set [member Viewport.debanding] on the root [Viewport] instead.

Enables FXAA in the root Viewport. FXAA is a popular screen-space antialiasing method, which is fast but will make the image look blurry, especially at lower resolutions. It can still work relatively well at large resolutions such as 1440p and 4K. Some of the lost sharpness can be recovered by enabling contrast-adaptive sharpening (see [member rendering/quality/filters/sharpen_intensity]).
