Inventor 2015 graphics display random objects

[Anonymous]

Since upgrading to Inventor 2015, about once a week we get a graphics issue on most of our computers (see screenshot below). This will happen with large and small part count assemblies. It seems to appear when doing a pan, zoom, or rotate, but it is not predictable as to when it will happen. It will usually go away for a short while by adjusting the min. frame rate in the Applications options display tab, but it will come back.

This is occuring on several of our computers running both NVIDIA Quadro FX 1700 with various drivers (8.17.12.5849; 8.17.12.9573; 9.18.13.4066; 9.18.13.4121)

And Quadro 4000 with drivers (8.17.11.9810; 9.18.13.3221)

Has anyone seen an issue like this before?

Thanks, Scott

What do you have for your graphic card via Options?

Update to the latest driver on the Nvidia site..

FX1700 should be driver 341.44

First thing I do before I update Inventor is update graphics card driver to the latest version..

But yes those kind of issues come up quite often around here.. Updating the driver is more than likely always the solution..

I'm running in Performance mode, though this issue has occured in Consevative mode as well.

Re. Drivers, I thought I was up to date, but I see that I was on 341.21. I updated this morning to 341.44. I'll update this post if I still have problems.

Thanks,

After doing all of the above, and still seeing the problem, I got in touch with Autodesk. They provided me a new dll to fix the graphics problem. They say that his dll will be included in 2015 SP2. It has been a couple of weeks now and I have not had any issues, so the new dll seems to have taken care of the problem.

Thank you Michael & mgyvr for your help!

I did come up with a work around that seems to help rectify the issue every time it comes up. First you must locate the part that is causing this issue and open it concurrently with the assembly. When the issue shows up, go to the part and move the EOP marker up until the artifacts disappear. When that happens, move the EOP marker back to the end. Save, and update your assembly. This should resolve your issue for as long as you have the assembly open, but if it does not just do the above once more.
