Sharpening

FXAA 4.0 has as a sharpness slider. FXAA 4.0 applies a special kind of sharping which can be applied in a single pass in conjunction with super-resolution. Here is a bilinear 2x2 up-sample,



FXAA 4.0 Super-Resolution set to sharp, note the sharpening is different than an un-sharp mask. So extra sharpening with a classic linear filter can be applied over this if desired.


Sharpening - Without MSAA Input
Sharpening without MSAA input reduces the AA quality slightly. Here is bilinear 2x,


Here is what this would look like at native resolution,


And FXAA 4.0 2x super-resolution with sharpening, note in this case the render only renders 25% of the pixels/frame as the image above. The sharpness of this image is limited by FXAA 4.0 only one sample from the current frame and one sample from the prior frame per a 2x2 group of output pixels, and needing to do AA also,


Another example, here is a native no-AA without resizing,


And the same with FXAA 4.0 at the sharpest setting,
