Total windows freeze on Surface laptop 3

Rhino Rhino for Windows
1

Hello, I am experiencing an ongoing situation with my Surface Laptop 3 While running Rhino 6 (and 7WIP). When I work on Arctic, Rendered or Raytraced display mode Rhino freezes at some random point after 15-30 minutes and it causes a total Windows freeze. Ctrl+Alt+Del not working either, I have to force reset. I have zero problems and a pretty snappy response when working on shaded, Ghosted, or wireframe etc.
I have come to understand through reading some relevant topics here that it may be an intel iris driver issue? Could you please confirm?

I suspect the display chip on your Surface is inadequate.

I would try this:
In Rhino Options > Advanced,
Search for “UseHardwareDriver”
Change it to False
See if that runs any better.
There really isn’t much else to try.

Thanks for the suggestion!

I am writing for the record (just in case others face the same problem) that I did try updating my drivers through Intel’s download page. Installed the DCH driver for Iris Plus 655, version 27.20.100.8190 and date 5/5/2020 (so it was published 5 months after the OEM one I had on). So far I have seen no differences in actual performance in regards to display speed etc, but the total system freeze seems to have stopped.

  • big bonus: some random screen dimming which seemed to happen in relevance to screen content went away, yay-
    I will try your suggestion and report whether there is a change here or not.

The Intel chips are not accelerated. You will never get good performance out of them but what you’re describing sounds right.

oof also just tried switching openGLUseHardwareDriver to False in the advanced settings and it is a no go apparently. It produces initially a non responsive Viewport, and after restarting Rhino, It is a no-shadows-whatsoever situation. So I quess I will keep that switched to true. Worth the try however.

Thanks again.

That’s true.
Turning off the driver will disable a few features like shadows that are dependent on OpenGL.
That is a last ditch effort to get Rhino running on unsupported hardware.
In this case, it sounds like the driver update and having UseHardwareDriver on the the best option for you.

Marking this as solved, since the freezes seem to have stopped for 5 days now.
