68040 & VT2.0
Ok guys, here's the scoop on the '040 problem. I am very surprised that no
one has really responded to the real problem. Here goes. Forgive my petty
arrogance.
Lightwave 2.0 was code written specifically for the '882 math chip which is
(by my understanding) very good at trigonometric functions and has calls
for them. The '040 chip has a different set of calls and does not support
the advanced trig functions (these are needed for certain textures and
ray-tracing). However, if Lightwave were written for the '040 it would run
rings around anything else. I was told that an '040 version running at
28mhz could be FOUR times faster than the '030 version 2.0 running at
33mhz. It would SMOKE!!! The reason for this is that every time Lightwave
calls for Trig stuff that the '040 does not do via hardware, it calls to a
library and this functions gets done in RAM with the 040's simpler (but
much faster) functions. It's here where the slow down occurs.
The solution? Just wait. It's coming. Trust me.
