Yes, that's true. DigiBooster 3 cannot be expected to be faster than DigiBoosterPro 2.x due to MUI usage and more advanced player. There is some room for improvements however, if demand for 68k version will be high. On the other hand limiting DigiBooster 3 future development to weak, 20 years old processors is not the right way. All CPU hungry features will be made optional, but for serious DigiBooster 3 usage a PowerPC based machine running MorphOS or AmigaOS 4 is recommended. WinUAE on an x86 is a solution too.
