AMD released VSR, in response to Nvidia's DSR, they both do the same thing Downsampling. I haven't run an AMD card since they introduced the feature so I'm not quite sure if that feature is available on the older GCN products, or if it's only the newer ones eg. R9 290/290x and R9 285 that support it. Just go through your CCC and see if there is an option for VSR in there somewhere.
