I'm running ReLive version 17.4.3 on a RX480 in Windows 10 Creators Update. Ever since the last few driver updates, GPU scaling on my card no longer works. My old PC games that run in resolutions other than 16:9 stretches to fill the screen instead of having the black borders at the sides even with GPU scaling set to ON and scaling mode set to Preserve Aspect Ratio.
I was wondering if the folks at AMD were aware of this issue? If not, I'll submit a detailed report through the webform.
