better settings for the blitter

could it be possible to have a way to set the speed of the blitter ???
like with the cpu 100% 120% 140 % .... etc...
I ask because some games are really to fast with immediate blitter but slowdows or 15 fps without... A way to set it more precisely should be great.

No. It would be really unreliable and change between versions.

To be more precise:
  • Yes, it is technically doable.
    After all, the Blitter cycle timing is part of UAE and can be changed like any other part of the emulator.
    This is not necessarily simple depending on the coupling of that code but it is doable.
  • However, will Toni do it?
    No, because it would cause programs which rely on Blitter timing to misbehave in seemingly unpredictable ways.

If programs used the Blitter in OS compatible ways this would have chances of working better but with games banging the hardware without much respect for rules set in the Hardware Reference Manual this would very likely cause many of them to misbehave rather than speed up.
