Reducing Hidden Edges processing time

Does anybody know exactly what dictates the speed a render is processed?

The reason is I am thinking of increasing RAM to 1 GIG

AMD 1600
512 Meg of Ram

Obviously as soon as I hit the go button, CPU processing goes straight
to %100 but my memory never seems to be hit very hard

I have set MEM Cache to 99000
Resource cache to 64000

but but hidden line times do not seem to alter at all (using the default
memory ettings)

Is my processor the bottleneck

A better processor will help mate. Not really a RAM issue.

Bear, what processor would you recommend? Currently I am testing a
pentium 4 2.4 GHz with 2 gig of Ram. I still max the CPU in
MicroStation.

Hi,

You will *always* max a single CPU regardless of its nominal speed (you basically stall the
box until MicroStation goes back again to idle waiting for user input, and this will happen
even if you can envisage a 10 GHz CPU).

OTOH dual CPU will leave at least 40% of juice for other tasks during the entire process.
Again, regardless of its CPU speed.

In other words this is a matter of balancing of the relative CPU load, as opposed to utilizing
the CPU speed per se.

Thanks guys.

I have established that additional RAM will help rendering, but I prefer
hidden line drawings, so its back to e-bay for more another cpu
and some water cooling.

Having just upgraded, here's what I was told-

CPU speed alone won't guarantee fastest operation; you also need the
fastest
front side bus (apparently 800 MHz) Also, consider getting Dual
Channel
DDR memory with a motherboard to support it; then 8x AGP & 128/256 MB
Video Card to access that; then there's Intel Hyperthreading but
buggered if I know if that's any advantage.........

 

Raw power I understand- I was just making sure I was loading up the machine
in the correct direction.

I like the info on the banded rendering. We do render in bands, but the
input of numbers of bands, and memory allocation was arbitrary
until now.

And to clarify

I actually meant "hidden line removal" not rendering (although we do both)

Thanks
