We use Inventor 2012 on a workstation with these components:
OS: Windows 7 x64
CPU: Xeon 2.80 1333MHz 12M X5660
RAM: 8 GB
HDD: 250 GB 10000 rpm
Grafic Card: Nvidia Quadro 4000 (2 GB)
When we use a large inventor assembly and we rotate these assembly, some or many components dissapear then when we not execute any moviment on assembly, all parts are visible.
We use last Inventor certified driver for this grafic card and we re-install all autodesk suite but no works better.
Moreover, via an external software to Autodesk, we verified the performance of the GPU and never exceeds 30% usage.
Do you have any idea how I can configure Inventor to improve performance and that Inventor use over 30% of the GPU?
Thanks and regards!
First, we try with option "Performance". We applied and then restart inventor.
Then we did same process with option "Quality".
Both got the same problem
Thanks for your help!
Then I have no idea-- sorry. You've got a good card and it ought to work. Sounds as if my dinosaur of a system works better than your nice shiny new one! I can open an 800-part assembly, the memory indicator immediately goes yellow (and soon into red if I do anything beyond look at it), but it rolls smoothly and easily, and no parts disappear-- and I'm driving a 2560 x 1600 monitor, too.
The bottleneck may not be in the GPU. Typically hardware uses as much as it needs and can get, so if its only running at 30% telling it to use "more" wouldn't improve much of anything. That value may also be an artifact of the means used to calculate the value (its not a direct measurement); for example, it could be running full out in short spurts as the screen refreshes the image at designated intervals.
You may be bumping up against another problem, as not everything goes on inside the video card even for displaying. What does the RAM usage look like when doing this? Processor activity?
yeah, bottleneck could well be elsewhere...
Things that spring to mind:
8gb ram isn't that massive in this day and age with cad - if it's using a virtual page file at all it can kill performance.
Try running MemProbe that's in Inventor's bin folder (default location: C:\Program Files\Autodesk\Inventor 2012\Bin ) - see how much physical and virtual memory Inventor is using (if it's over a gig of virtual then could well be crying out for more ram).
Xeon chips are good for multi-threaded apps, Inventor isn't a mult-threaded app... Looking at single-threaded benchmark: http://www.cpubenchmark.net/singleThread.html there isn't a X5660 listed but there is the quicker X5690 which is quite far down the table. the X5660 is going to be even slower with its 2.8GHz clock compared to the 3.5Ghz of the X5690. So, despite the mental cost of the X5660, it could well be struggling too...
If you're running big assemblies then I would imagine either (or both) of these being the bottleneck before the Quadro.
If it's hardware issue, then my vote for bottleneck goes to: hdd and cpu.
8Gb of ram is enough for assemblies up to 10000 parts IMO.
Anyway, how big assembly do we speak about?
CPU does not exceed 20-23%
Uses 4.3 GB of RAM 8 GB
Assembled pieces 9024/563. Can be problem of restrictions?
We run MemProbe and always have the first value to 0, does not change. I ran MemProbe on multiple computers and the result is the same. Maybe I do something wrong.
I attached a screenshot screen.
