John,

Are these suggestions for the Quadro4 750XGL, also? I'm running the
41.03 driver. I don't see a check box for fast-mipmap-linear. All I see
in 'Direct 3-D Settings' is a 'MipMap Detail Level' pull down with five
options: Best image quality(default), High image quality, Blend, High
Performance, and Best Perfomance.

aaron,

    Opengl settings, not directx.
Review our exchange in 5.3 NG. The suggested settings in that thread are working
well for my 750 xgl.

Darvin,

I am using driver 41.03.
This is what you posted in 5.3 NG:

Desktop > Props > settings > Adv > 750 xgl > additional > opengl
Fast linear MipMap - on
Enable Overlays - on
Maximize Texture Memory - on
Vertcal Sync - off
PCI memory = 16 meg

First off, I can get to: Desktop > Props > settings > Adv > 750 xgl.
but I don't have an 'Additional'. There is a green arrow on the left
side that gives a flyout menu. And in that I can go to 'Quadro4 750 XGl'
> 'Perofrmance and Quality' > 'Open GL Settings'. That changges the
'Quadro4 750 XGL' tab, and at the top of that is a scroll box labeled
'Performance and Compatibilty Options' in that I can check on and off
the following:

'Disable support for enhanced CPU instruction set' (not checked)
'Enable quadbuffered stereo API' (not checked)
'Enable Overlays' (checked)
'Maximize Texture Memory' (checked)
'Enable Conformant Open GL Texture clamp behavior (not checked)

Below that is: 'Multi-Display Hardware Acceleration' with a gray-out box
that says 'Single display mode'

Below that is 'Default Color Depth for textures' set to 'Use Desktop
Color depth'

Below that is 'Buffer Flipping Mode' set to 'Auto-select'

Below that is 'Vertical Sync' set to 'Always off'

Below that is 'Use oup to XX MB of system memory for textures in PCI
Mode' set to 16

Below that is 'Custom OpenGL Applications Setting' set to blank


I do not see anything to set "Fast Linear MipMap"

aaron,

    Where are you getting the 4103
driver. I'm still using 2942 on w2k-sp2. There must be an overhaul on the
settings applet. Ping me a link and I'll grab the 4103 and play with it
tonight.

    No time right now! Having too
much fun drilling holes in fiberglass parts and anticipating the
itch<g>.

Matt,
This is a Dell 340 2.53GHz, 1GB RDRAM, 15k rpm 18GB HD, Win2k SP2 with a
Quadro4 900 XGL, running at 1280x1024, 75Hz
All mentioned software is installed pretty much out of the box, only some
"obvious" tweaking done.

John,
Went home, had a deep and wealthy sleep, came back today morning.
Things didn't change.
IV6 can rotate a 8000 cubes assembly at 2.8Hz, and a part consisting of an
array of 8000cubes at 59 Hz.
Mysterius - both files are looking exactly the same on screen, one is very
fast, the other one is very slow.

Maybe one of the graphic gurus can share his wisdom on this?

BTW, MDT6 shows a similar difference between an assy of 8000cubes and a part
with 8000 arrayed cubic features, but not as great.

Leo,
maybe it has something to do with the simplyfication methodes of inventor
(gift wraping or suspressing from display).
AFAIK Inventor tries to simplify the graphics of each part separate and
makes now difference between separate parts or instances of the same part.
Maybe something like this makes the difference? I think you are right,
saying
a cube can't be simplyfied (a cube has allways 12 triangles), but I believe
Inventor tries to do it again and again. And of course a single part of 8000
cubic features can be simplified (to it's boundary box, a single cube
again).
Please correct me if I'm wrong. (Did not try it out by now.)

Re:

Michael,
I'm really out of ideas here.
There is no simplifying to be seen on screen - in fact, in both files all
96000 triangles stay intact and visible, no bounding box or the like. On
screen, both files look exactly the same.
The only reason I can think of why IV rotates a 8000 feature part more than
10 times faster than a 8000 parts assembly is how the graphic subsystem gets
the informations about what to display - either 12x8000 triangles (read:
slow) or 96000 triangles from one solid (read: fast).
Anyway, in my real life work, I'm dealing with multiple k parts assemblies,
most parts being of simple rectangle shape. And IV is the slowest package
I'm using, and it grows slower with every release.
