My powerbook g4 is running really sluggish, while using lighwave 8.3

The computer has 2 gigs of DDR SDRAM and a 1.67 ghz powerpc g4 processer.

the object that I am building and rendering is the chandelier from the tutorial package the signiture courseware. Its about 111,000 polys.. But on the tutorial his computer is running fine and he only has 1 gig of ram

is there somthing I can do to make my mac run LW8 better??

Thanks for any help

Which video card do you have in there? I have a 1.5 Ghz powerbook with a ATI Mobility Radeon 9700. It works well, but yes, it does get sluggish when the polygon counts get high. My PC doesn't get so bad. I believe it's a difference in the two platforms with respect to Lightwave, which seems to be more optimized for PCs.

You might be able to optimize some of Lightwave's display options..simple wireframes, etc or if possible, hide geometry that you're not dealing with...either with layers or the Hide command.

Keeping up with technology is such a pain. You can get a lot of information about your computer by click the little apple in the upper left, selecting "About this Mac" and then clicking the "More Info..." button. It's somewhere in there in Graphics/Displays.

The OpenGL response of Lightwave is not that good for the Mac. Yes, I think it's an optimization issue.

I switched to Luxology modo for modeling, and its OpenGL refresh rate is multiples of times faster (the frame rate is higher).

I still render in Lightwave, though.
