How Genshin Impact runs on the Radeon RX 580
Our estimate puts the Radeon RX 580 at about 57 fps on High at 1080p in Genshin Impact, which means it runs acceptably. On Low the same card manages about 109 fps, and on Ultra about 41.
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: Medium (about 80 fps); 1440p: Low (about 78 fps); 4K: under 60 fps at every preset, best is 43 fps on Low.
