No argument.
Now tell me where I said it was CPU expensive please? A quote from my
email:
can bog an Amiga down regardless of processor: the bottleneck is the
*CHIPRAM BUS*, *not* the *processor*,
and the bus bottleneck has a serious impact on performance.
I've gone through this argument 10,000 times and people just don't seem to
get it. AGA is slow, old, massively underpowered, has a fill rate that makes
a toddler look like a speed artist and it is tied to a system bus
which runs ar a fixed 17Mhz (IIRC). You can have as speedy a processor as
you want, but it can only shove those bits over the motherboard at a
fraction of its speed, and *that* is what kills performance.
