Anyone know how to Maximise SL performance?

Im looking to maximise SL performance on my Imac G5. I have tinkered, unsuccesfully with the preferences on SL, no Joy. Lag is killing me all the time. Anyone know how to sort it?

Here's an orphaned article on the SL wiki that might help. I haven't looked very hard to see if this has been posted elsewhere on the wiki.

(For some reason this article is in the help section for the wiki, rather than somewhere it can be found.)

I turn trees off in the debug menus.

(ctrl-alt-D to show 'em)

In fact, this time last year when I was "born" I was on a pre-intel macmini, and I had to turn clouds & trees off, and keep everything turned down real lowwwww.

Oh, and in primmy areas, turning anisotrophic filtering *on* works better. Sometimes.

If you could make SL running on half the core, it would probably run better than on a fully operational dual core config.
there is a patch for pc to fix the issue, for mac there may be a patch.

Then again, on a macbook pro (intell dual) the engine seems to do the trick for me, without patch.

this is a most educated guess, and might be wrong.

there are problems in Windows on some dual core machines not running right with single core apps.. and turning the affinity for 1 core can help it out. I havent seen this happen on OSX. Alos the iMac G5 only has 1 core so its nothing to do with it.
