The new Navi GPUs - RX 5700XT and RX5700 include Radeon Image Sharpening which is promoted as a differentiating feature in the GPUs.
I find this topic interesting so I have run some tests to look at what results I get running Contrast Aware Sharpening filter in a number of games.
I am adding the test results here first as I complete the testing and I will add more details about settings later.
