Idle Rhino crash + OpenGL lost?

Hello,

I´ve tried several searches worldwide without luck. I also agree that my way of hardware usage is a bit intense, however here is the case:

Hardware specs - Dell G3 laptop, 8GB RAM, Intel HD 630 + dedicated Nvidia GeForce GTX 1060 6GB VRAM.
Software specs - Win 10, Rhino 7, all updates including drivers up-to-date.

I run Rhino + Grasshopper + AutoCAD on 3 displays- laptop screen is opened as secondary in terms of working time for AutoCAD purposes, 2 main working screens are connected via USB Dell DisplayLink. The fact that dedicated graphic card is invisible with laptop display closed is known issue.

If I work continuously in Rhino, everything is fine. But if I focus my attention to AutoCAD (laptop display) for more than 5 minutes, Rhino seems to fall asleep. Maybe even fall apart. Going back to Rhino screen and clicking the mouse it crashes instantly without Crash Report Dialog and if I run it again, it opens with OpenGL 1.0. That means GTX1060 is invisible for Rhino (laptop display opened).

I guess it is somehow connected to Windows, power management. May it be that anyone has come along similar issues, and possibly found solution to this behavior?

Thank you very much in advance,

Pavel

Hi Pavel -

It is recommended to have 4 GB of VRAM per screen in use (and double that depending on the resolution of the screens), so, yes, with only 6GB available, you are taxing your system.

I don’t know what you mean with “in terms of working time for AutoCAD purposes” - do you have Rhino only on the display that is defined as “primary” in the Windows OS settings?
Perhaps if you post your SystemInfo data, something else is made clear.

Hello Wim,

please find attached the textfile with system information.

Primary display in Windows is set to laptop screen, and there the Total Commander, AutoCAD, Office apps etc run so I can search, grab & prepare input data without the need for Alt+Tab switching. Rhino and Grasshopper are set to 2nd and 3rd display in terms of Windows settings, but those are the two screens I look at for the most of worktime.

Best regards and thank you!

Hi Pavel -
A quick check, I suppose, would be to disable the Twinmotion plug-in and see if that makes a difference.
My money, however, is on the USB DisplayLink.

I would strongly recommend Rhino to be used on the primary display. If you don’t want that, at least make sure to connect the display that Rhino is used on directly to the GPU.
