How Minecraft: Java Edition runs on the GeForce GTX 1660 Super
Our estimate puts the GeForce GTX 1660 Super at about 225 fps on High at 1080p in Minecraft: Java Edition, which means it runs comfortably. On Low the same card manages about 300+ fps, and on Ultra about 162.
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: Ultra (about 162 fps); 1440p: Ultra (about 116 fps); 4K: Ultra (about 65 fps).
