View Full Version : render better?

12-07-2004, 05:58 AM
I noticed in the Windows Task Manager under the Performance tab, that:

during a render my machine only uses about 55% of the CPU power

shouldn't it be able to render faster if Scotty was giving me full juice?
how would go about increasing my CPU usage?

I'm running LW7.5 in Windows 2000.

Thanks in advance,

Use as many threads as your computer can handle (depends on how many processors you have and what kind of processor). you can change this parameter in the render options panel

that's normal, you have hyperthreading on your computer.
when you have 1 cpu and the cpu in the performance tab is at 50-55 it means
it using fully your 1 cpu but not using hyperthreading

as say weetos you can render in LW with more than 1 thread (so using multithreading) but you have to know that depending on your scene,
it will render faster and sometimes a little bit slower...
it depends on your scene..

so if you have 1 cpu you should have 1 thread only by default.
use more threads only if you know that it will render faster with your scene..
(render your scene in low-rez and compare with different number of threads)
