The problem is more to do with how slow AGA is for 256 colour graphics speed with the insane 'solution' of having EIGHT bit planes not byte per pixel.
Given the PC version only needs a 486 66mhz and the 060 is more powerful per Mhz it should actually run better than a Pentium 66mhz.
Is there a patched version to use with video graphics boards inside Amigas or does it only work with native AGA chipset?
