The Amiga in normal operation works in single field operation. For you techies out there it means it always drives the field flag to the same value on both fields. The result is on a PAL TV that is 50fps, and in NTSC that is 60fps.
The maximum number of lines the Amiga can generate in that mode is 288 PAL, 240 NTSC.
The Amiga CAN however work in interlace mode and in that mode can only do 25fps and 30fps respectively, but the maximum number of lines in that mode are 576 and 480 respectively.
Just because the hardware can display images this fast, DOESNT mean the code can generate them this fast. Not every game could update it's screen as fast as the Amiga refresh rate. A LOT of games were coded poorly and could not finish updating the screen in time and thus the same image had to be displayed twice. Worse case this can halve the frame rate.
Most games we consider to be excellent games are 50fps on the Amiga, but they are the best of the best.
