Autodesk inventor 2012 has worked exclusively on Direct3D. At the moment, there is no single test that is likely to correctly identify performance hardware.The results of such tests as Cinebench, 3DMark, SPECviewperf - untrue. But the need to determine the real performance of video cards is growing. According to this offer on their own to determine the performance of different video cards. For the test we will use the internal mechanism of Autodesk inventor 2012 definition of refresh rate.
One benchmark test that you can perform is to run the Post Statistics.
This requires an understanding of registry editing.
Go Start>Run & type “regedit”. Click OK & navigate to this branch: HKEY_CURRENT_USER\Software\Autodesk\Inventor\RegistryVersionXX\System\Preferences\Scene Manager\Debug\Post Statistics, set the REG_DWORD to 1.
The next time Inventor is run, a small information box will appear at the bottom of your screen.
We twist the assembly . Pattern editing in the assembly "1000.iam", we change the number of parts in the assembly until the refresh rate will be equal to 15 Hz. This is the minimum, and psychologically comfortable refresh rate.We work exclusively in the factory settings
The results report in the next volume:
1. The operating system and its capacity
2. Processor
3. RAM
4. Video card
5. Number of parts with assembly at a refresh rate of 15Hz.
Windows 7 64 bit
Intel Core i7-x990
Nvidia Geforce GTX 580
RAM 12Gb
Refresh rate 300 part -15Hz
Interesting..
Results (shaded with edges)
Refresh rate 200 parts - 15.63Hz
Results (wireframe)
Refresh rate 400 parts - 16.13Hz
500 parts = 15.8Hz
600 parts = 13.8Hz
Interestingly, if I change the first pattern from a 10x10 to 5x5 and the second pattern to 5, 125 parts = 11.7Hz
All done as "shaded with edges".
wow.. this has got me curious.. mbenoy got some excellent results.. Is it the xeon or the quadro or the velociraptor or all combined.. We need more results.. Come people.. Do it.. Only takes a few minutes.
If interested, while rotating:
CPU Usage = 50%
GPU Clock = 45%
GPU Memory Usage = 5% (of 1GB)
If you take a look at each of the cores and how it breaks down to get the 50%. Obviously, the CPU cores jump all over the place while making a total of 50%. The following are very rough estimates of the ranges of each core during that time:
Core 1 = 80-95%
Core 2 = 70-85%
Core 3 = 8-30%
Core 4 = 30-55%
I don't have time to try this at work tomorrow, but I'm curious-- does the pixel count of the display have an effect on this benchmark? My laptop screen is 1680 x 1050, but the screen I mostly use it with on my desk is 2560 x 1600, 2-1/3 times the number of pixels. I suspect that the GPU works harder to calculate more pixels, so these results will have to be related to pixel count, I think.
For the test results add one more parameter - the screen resolution.
Intel core i7-x990 - 1900x1200 load: CPU- 12%; GPU-9%; GPU memory 64MB.
Intel duo core L7500 - 1024x768
Hi,
My results with 15Hz: slightly above 500 part (see attachment) .

Huh?? We have identical CPU/Motherboard and I've got twice the RAM and a video card that "should" kick the FX1800's butt yet you have more than twice the parts count. Something ain't right
Mine is 1920 x 1080. I'll try lower now.
I give up.. Changed to 1600 x 900 and it made NO difference at all. I don't understand.
I was repeat all. It is this same.
> video card that "should" kick the FX1800's...
I totaly do not agree, sorry.

Why don't you agree? Its suposedly one of the top graphics cards out there. and beats the FX1800 by a long shot in EVERY benchmark test there is. These results I'm seeing are making me completely think twice now about everyone saying a quadro card isn't needed for Inventor. These tests show a much different story. All quadro cards are in the 500+ part range. Where my "top of the line" gaming card is falling very short with only 200. I know very little about why one card is better than the other for Inventor so please inform me.
We need some more results from guys with gaming cards..
Aha.. After looking at malenki's picture I see he is using compatibility mode. When I switch to that now I get 400 parts at 14.93Hz while rotating the assembly full speed with my space pilot. at 1680 * 1050 resolution. Better but still lower than the quadros.
Malenki, try with performance hardware mode.
> Why don't you agree?
Because I do not use games, I do not the card need to... Only the CADs.
And I never had problems with Quadro FX (1500, 1700 too).
The best benchmark is the "comfort rating in work". As in this test.
It is my opinion only.
>Malenki, try with performance hardware mode
OK, see attachments: essentially no difference !
BTW. Version of Nvidia driver of my card is 276.14 now (all values default).
Interesting again.. I get nearly double the refresh rate with compatibility turned on. While your quadro shows no decrease when switching to performance. Something seems fishy...
I get around 500 parts for the 15Hz rotation at 1920 x 1200 in Performance mode, no difference in Quality mode and a major drop to 7 Hz in compatibility mode.
> Something seems fishy...
What can I say? It is prusas test. I try it... out of curiosity. I'm not a hardware expert (software too), but it is what it is.
I'm only designer... . Or maybe the guru of Autodesk react to this "fenomen"?
