IV6 is the slowest...

Group,
I did some testing to compare the graphic speed of various CAD programs,
using the 8000cubes assembly and would like to bring the results to
everybodies attention.
The PC is a Dell 2.53GHz, with a Quadro4 900XGL. To get the frame rates I
used either the post statistics or a utility called FRAPS1.9.

shaded mode:
UGS18 62Hz
MDT6 8Hz
MDT5 7 Hz
IV4 4.33Hz
SW2001 4Hz
IV5.3 3.3Hz
IV6 2.7Hz

3d wireframe mode:
UGS18 72Hz
MDT6 24Hz
MDT5 22Hz
SW2001 3Hz
IV6 2.9Hz

Note: The 2d wireframe of MDT mode is very, very much faster, as has been
good old MDT3.01 in shaded/wireframe mode.
Definitely IV6 is by far the slowest package.

Regards,

Min Full LOD Frame Rate change to 7, Min Gift Wrap Tolerance set to 0.2 (Registry), Enable Overlays
and fastlinear-mipmap-linear in OpenGL settings of display properties and re-run the IV test,
because I can can get 25Hz with all parts visible on a 12000 part assembly in 5.3 with a lowly
Quadro2 card.

WARNING. CHANGING REGISTRY SETTINGS CAN MAKE YOUR MACHINE BECOME USTABLE AND IS NOT RECOMMNDED.


Run Regedit and change the following settings:

John,
I did as you recommended, and in adition swaped the driver to 41.03, but no
real difference.
The 8000cubes example is a tough thing - as it consists of simple cubes,
there is no geometry that can be simplified (or call it cheated) by the
driver. That's the reason why I use it to compare the graphic speed of
different systems.

It would be easy for you to compare the speed of IV to MDT - just save as a
sat file and open this in MDT. The graphic speed should be independent of
constraints, parametrics or features.

I will have a "play" myself when I get a spare moment. It could be another useful little routine
for my hardware bashing next month - will report back my findings and tests used.

I found it via search on LOD whatever that is. Thanks John, not really up on
that stuff, myself so I saved your post to refer to later ... if I can
manage to hang on to it, that is or worse, even remember it exist.

Now I'm really out of ideas...

Just tried to produce a 8000cubes array as features in a part file.
It took IV 12 minutes to create this (versus several seconds to do the same
array in an assembly file).
And then:

IV CAN ROTATE THIS WITH 59Hz!!!(shaded) and 100Hz wireframe!!!

Anybody can explain this?

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.)

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.
