Quite possibly. I forgot to mention that this was about 6 or so years
ago and given how much things have moved on I wasn't really expecting the
current crop of RISC based machines to have the same flaws.
Well, that'll teach me to fling off a quick comment without thinking too
much about things first... :)
Bye for now,
Jamie.

Pretty good, My PII-300 manages 2'20" with method 1, and 3'3" with method
2.
Oh, and please note I wasn't having a go at Macs, in fact I'd forgotten
that they were RISC based while I wrote my previous post.
Bye for now,
Jamie.

The 333MHz sparcv9 processor used in the Sun Ultra 5 is a RISC processor.
POV-Ray renders there faster than with a P-II 350MHz.

I saw the other posts about speeds and remembered I quick look I did a while
ago. Alpha's came out at about 2-3x pixels per megahertz compared even to a
TBird.
Alpha's smoke most other CPU's when it comes to raytracing :)

Physics is no fun if you disregard friction.
