Radeon Image Sharpening was brought along with the launch of the Radeon RX 5700 Series graphics cards as a way to help improve image fidelity by increasing the sharpness of an image through a one-click solution. But, at launch, it was limited to the Radeon RX 5700 Series of graphics cards but only with DX9, DX12, and Vulkan titles launching in Windows 10.  As of this driver, the support has been expanded, and while it’s not an all-encompassing solution it does expand the supported graphics cards to include the Radeon RX 470, RX 570, RX 480, RX 580, and RX 590 as well, but only with DX12 and Vulkan support with DX9 being left out on this one but still requiring Windows 10.  Those itching for it on their Vega cards will have to continue to wait however as it’s not getting RIS this time around, but it’s good to see the expansion begin.
