<constant name="SCALING_3D_MODE_FSR2" value="2" enum="Scaling3DMode">
Use AMD FidelityFX Super Resolution 2.2 upscaling for the viewport's 3D buffer. The amount of scaling can be set using [member Viewport.scaling_3d_scale]. Values less than [code]1.0[/code] will be result in the viewport being upscaled using FSR2. Values greater than [code]1.0[/code] are not supported and bilinear downsampling will be used instead. A value of [code]1.0[/code] will use FSR2 at native resolution as a TAA solution.

Use the [url=https://developer.apple.com/documentation/metalfx/mtlfxspatialscaler#overview]MetalFX spatial upscaler[/url] for the viewport's 3D buffer.

Values less than [code]1.0[/code] will be result in the viewport being upscaled using MetalFX. Values greater than [code]1.0[/code] are not supported and bilinear downsampling will be used instead. A value of [code]1.0[/code] disables scaling.
