Thanks Robert and Chris! > Do you see any OpenGL errors reported?
Unfortunately, no. The symptoms are "freeze", then app shutdown with return code 0xC0000409; if there is a debugger attached, the error appears to be coming from the nVidia OpenGL dll. If there is no debugger attached, there is no other error displayed. There are a few more clues in the Windows Event Viewer, ------------------ The description for Event ID 1 from source NVIDIA OpenGL Driver cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer. If the event originated on another computer, the display information had to be saved with the event. The following information was included with the event: A TDR has been detected. The application must close. Error code: 7 (pid=17844 tid=14328 [APPNAME].exe 32bit) Visit http://nvidia.custhelp.com/app/answers/detail/a_id/3633 for more information. The message resource is present but the message was not found in the message table ----------- So it looks like we give the driver something it has trouble to handle. > I'd suggest starting with small models that you know are causing problems and have a look at these first. Yeah I think the next step is to figure out which model (models?) cause that issue, and inspect it. > It would also be worth trying things out on a different OS, hardware, drivers etc, to see if there are any correlations. Some of my colleagues have not been able to reproduce the issue on their workstation. The only difference is the hardware. That's an annoyance. > I've found the Windows Nvidia drivers to be really bad about actually reporting OpenGL errors unless you create a debug context. I was not aware that there was such a thing as a debug context, I'll check into this.
