Whole screen flickers while rendering with Revit 2017

[Anonymous]

Hi, 

I have a problem when rendering in Revit 2017: in the rendering process, the whole screen (not just Revit window) goes black for a couple of seconds and then recovers (a long "blink"). It only happens while rendering with high resolution (300 DPI). 

I have an i7 4790k, 16 GB RAM, a 250 GB SSD and a GTX 1060 6GB (but I have also tried disabling the hardware acceleration). I have also tried to throttle the CPU at 90%, but I got the same results. 

Does anyone have any clue about the reason?

Thanks!!

OK, a little bit more of data, because it has somehow gotten worse by doing a repair. I still have the "blinking", but now it's impossible to finish a render on high. I have two different behaviours:

    With HW graphic acceleration: the render gets stuck with no error prompt, but the percentage does not advance. When I close the render window, I got an error of the graphic controler (journal58, attached). 

    With no HW acceleration, about the same progress, the computer reboots (journal 62)

I will try tomorrow a fresh start by uninstalling and starting from scratch, but the behaviour seems pretty odd with a fairly standard equipment...

This is definitely a graphics issue...!

looking at your journal file, it shows you have an Intel card as well as an NVIDIA card. That mean you're running optimus/hybrid technology which need to be disabled within the bios.

You can keep ignoring my suggestion, but that is the issue as we had to resolve this on 30+ machines...

More information about optimus

Good luck!

Mmmmm... That didn't crossed my mind. I will have a look at the BIOS and perform a clean installation this evening when I have access to the computer again. 

Many thanks

I did what you proposed, and the result is still the same... attached is the journal of the last round.

There is Hardware Acceleration error popping up at the end of the process.

I would uninstall the video driver, delete the graphics card from Windows' device manager, and restart the machine.  Windows will detect the card and assign the default driver to it.  Try to render it with HW Accelarion On, see if it crashes.

- If not, start installing GeForce driver from nVidia, working down from the latest.  If it crashes again, go for the older one.

- If crashes, then go to BIOS and disable GeForce card.  Go back to Revit and render, it will be using Intel card and if it does not crash, then it is most likely hardware failure.  Put the card in another machine see if it crashes Revit there.  If so, I think a replacement is in order.

- Also, check the motherboard manufacturer see if they have an updated BIOS for yours.  If so, flash it.

is someone rendering ok with the gtx1060?

So, at least the second options gave some result!! I can render ok with the built in graphic, and the flickering is not longer happening. 

The big question, should I RMA the 1060 or is it a general driver problem?

Thanks!!

Glad you were able to get this resolved. I knew it was a graphics card issue... Take care!

Have you put the 1060 in another working machine and run a Revit test render?

[Anonymous]

Nope, I only have one compatible motherboard. 

With this test, I understand that it will be either be the motherboard or the graphic card, but please correct me if I'm wrong...

I have been working for some time just disabling the graphic card, but now i finally had time to format and install the new graphic card, and... everything is still the same: the PC still crashes, and sometimes, the reder process stops with a graphic controller problem. 

Could it be a general problem with the Nvidia 1060?
