Doh, you are right. I'm not sure quite what I was thinking of when I wrote this, but you are correct. As long as the app has been designed to use the correct threads (I know under some SMP implications, there are kernel threads which use SMP and there are application threads which don't use SMP but allow the program to do multiple things at once), it's available to use multiple processors. >> Games, at least I've never heard of one that >> is, are not threaded nor SMP aware. > > Just as an FYI... > > QUAKE III's graphic engine was compiled with SMP support.

After all, the original GLQuake was written by them so they could play it on their high end Gl workstations. -- G-List is sponsored by <http://lowendmac.com/> and...
