OK....Why the slow orbiting in 3D window in AC9.?

[Anonymous]

Started playing around with our new AC9. Wanting to make sure everythings installed ok.
On one of our workstations, when you open up the Orchard example project, the 3D window has very very slow orbiting and panning and mouse wheel zooming. 2D window appears to be just fine in terms of zooming and regen.
The same example project in AC8.1 can have the Orhard 3D model spin around like a top .This workstation has a P42.8HT, Quadro FX1100 256mb, and 1.5GBpc3200.

On another workstation, one with a ATI Fire GL card , the 3D model orbits smooth and fast just like in AC8.1.

For antonins information,

Have ran both 8.1 and 9 on and AMD 2.8Ghz machine with 1G of ram and have also updated to an nvidia XFX6800GT (61.77 drivers) on XP with SP1.

Now archicad only runs with the internal rendering engine.

Application just hangs if I run in open GL.

If I install old drivers 52.2 or thereabouts, open GL is ok.

Thought above may be useful

There is a new option in 9 to have a background picture in the openGL window, I have found I get much a better openGL response if there is no background picture present

And that is a problem?

Okay:

Naturally, the more work you give the VPU driving OpenGL to do, the slower it operates. More like a union worker and less like the crew of United 713 last weekend who, despite a slow plane check by unionized Canada Customs, managed to get it clean enough quick enough to leave on time for Denver. And not break a sweat. And keep smiling. And quick with the jokes.

Here are some things to try to get OpenGL windows to work more smoothly:
1: Don't oversize the background image - make it exactly what the window size is. No extra figuring.
2: Keep the Open GL window smaller than full screen - say 1/4 screen area - depending on video RAM, there's a threshold above which it really slows down. Smoothness or size.... misery or despair?
3: There is no three.
4: Don't ask for OpenGL options that you don't need - emission, etc. - all I ever turn on is textures.... and then only at the end stages of a composition.

I just discovered this (again), too! When I posted at the beginning of the thread that I had had a problem with a 1 second delay before I could move in OpenGL ... this was it! Using just a BG color instead of an image, I have instantaneous and fluid response.

Geez Dwight, for "Canada's Funniest Architect" you sure can be surly

It was a joke?

Sometimes people write to complain. sometimes they want a solution.....
Did any of my suggestions help your speed?
