How does the ScaleFX internal resolution upscale work compared to how a core would do it?

ScaleFX is an interpolation shader. It sees patterns in pixels and tries to guess what those patterns would look like at higher res. It can’t make up detail that isn’t there.
Internal resolution in a 3D core actually increases the resolution at which geometry is rendered, so there is more detail produced. However, polygons are defined by their vertices, and new vertices will not be created.

So the internal resolution option for scalefx x9 doesn’t really increase internal resolution?
Yeah, I believe it refers to how many pixels it searches for patterns.
Ok, cool. Thanks for the confirmation of the explanation.
