How AION 2 runs on the Radeon RX 580
Our estimate puts the Radeon RX 580 at about 26 fps on High at 1080p in AION 2, which means it runs only on reduced settings. On Low the same card manages about 49 fps, and on Ultra about 19.
The graphics card is the limit here, so lowering the resolution or the quality preset is what raises your frame rate.
For a steady 60 fps, our estimate says: 1080p: under 60 fps at every preset, best is 49 fps on Low; 1440p: under 60 fps at every preset, best is 35 fps on Low; 4K: under 60 fps at every preset, best is 20 fps on Low.
