The '-t' should go on the command line, like this:
... where 'scene.xml' is the scene to render.
You can also change the default setting in infile.txt:

you also can edit the 'inifile.txt' file where it says
"num_threads" "1"
to "num_threads" "2"
My experience with my 2.4 Prescott HT was that using dual threads wasn't very useful (+5-10% Mutations per second, but Deathly killed other processes). My new C2D is a very different animal

(+90-100% M.P.S., Hampering computer use)

A good way to start indigo is to use
Code: Select all
start /belownormal indigo.exe -t 2 scene.xml
This works on Win XP. It will put the indigo process in a lower scheduling class ("below normal") so the pc doesn't run so slowly for other processes.

Prescott cores haven't always been dual core. Also, hyper threading itself doesn't mean dual core - it provides two logical cores. Though, if you have a dual core with hyper-threading, you could use 4 threads!
That might explain the performance difference.
