How Crusader Kings III runs on the GeForce RTX 3060
Our estimate puts the GeForce RTX 3060 at about 153 fps on High at 1080p in Crusader Kings III, which means it runs comfortably. On Low the same card manages about 290 fps, and on Ultra about 110.
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 110 fps); 1440p: Ultra (about 79 fps); 4K: High (about 61 fps).
