How American Truck Simulator runs on the GeForce GTX 1660 Super
Our estimate puts the GeForce GTX 1660 Super at about 76 fps on High at 1080p in American Truck Simulator, which means it runs well. On Low the same card manages about 144 fps, and on Ultra about 55.
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: High (about 76 fps); 1440p: Medium (about 77 fps); 4K: under 60 fps at every preset, best is 58 fps on Low.
