CPU Spike

rightnetworks

We have been using Sketchup 6 pro for some time.
And over that time we have has numerous users report Sketchup locking up.
Upon further investigation, Sketchup is just cranking along and not bothering to update the screen. The user see's a black window while taskmanager shows Sketchup bouncing around 50% CPU utilization. (on a dual core system)

I've found that simply spinning a model in the view port maxes the CPU.
The big difference is if you move it a little the CPU spike is short.
If you move it alot the CPU spike is longer. (hey it's got more math to do)
The "black outs" usualy occur with the big viewport changes.

I guess I want to know why...
We have Dell Precision M90 workstations. Dual 2.4ghz, 4gig ram, nVidia FX 2500M video.
Hardware acceleration is on.
we've turned down detail. (on trees etc.)
and we see this issue even on some small drawings.

We have all the Shadow/Sun/etc options disabled.
the OpenGL info is:
use hardware
use Fast Feedback
nVidia Quadro FX 2500M/PCI/SSE2
GL version: 2.1.1
GLU version: 1.2.2.0 Microsoft Corp.
using 0x anti-aliasing

Are we doing something wrong?!

ps. I'm an IT guy not a 3d guy so please keep in mind I'm not that fluent in Sketchup's interface.

Thank you,

Go to the window tab inside sketchup, then preferences and go to OpenGL, see if hardware accelaration is checked.
Using only openGL usually uses a lot of CPU power, if that doesn't decrese the CPU usage, not much else you could do.It also depends how heavy the models you use are, home many traingles they have.
Also SU doesn't take advantage of dual core architecture so it's doesn't really work much better on a dual core machine

oops, i only now notice you already have harware on...Well like i said not much else you could do.

What's the polygon count? Your idea of "low detail" might still be unmanagable for SketchUp.

In SketchUp -> Window -> Model Info -> Statistics tab, -> tick the box next to "Show nested components" at the top (drop down menu should also say "Entire model")
