Elabajaba 09f1bd0be7 Add port of AMD's Robust Contrast Adaptive Sharpening (#7422) ... # Objective TAA, FXAA, and some other post processing effects can cause the image to become blurry. Sharpening helps to counteract that. ## Solution ~~This is a port of AMD's Contrast Adaptive Sharpening (I ported it from the [SweetFX](https://github.com/CeeJayDK/SweetFX/blob/master/Shaders/CAS.fx) version, which is still MIT licensed). CAS is a good sharpening algorithm that is better at avoiding the full screen oversharpening artifacts that simpler algorithms tend to create.~~ This is a port of AMD's Robust Contrast Adaptive Sharpening (RCAS) which they developed for FSR 1 ([and continue to use in FSR 2](149cf26e12/src/ffx-fsr2-api/shaders/ffx_fsr1.h (L599))). RCAS is a good sharpening algorithm that is better at avoiding the full screen oversharpening artifacts that simpler algorithms tend to create. --- ## Future Work - Consider porting this to a compute shader for potentially better performance. (In my testing it is currently ridiculously cheap (0.01ms in Bistro at 1440p where I'm GPU bound), so this wasn't a priority, especially since it would increase complexity due to still needing the non-compute version for webgl2 support). --- ## Changelog - Added Contrast Adaptive Sharpening. --------- Co-authored-by: JMS55 <47158642+JMS55@users.noreply.github.com>		2023-04-02 20:14:01 +00:00
