I think title says it all. Just installed 2x 2080Ti's, running newest drivers and get the above message, in even the simplest of scenes, using production or RT. Version I'm on is: V-Ray for SketchUp 3.60.03

What exact driver version is this? Have you restarted the PC after installing the driver?

[delineator]

416.34 and yes, I had to restart after the drivers installed. BUT thats a good point - I may be thinking about the GFE update. Let me restart shortly and try again and will report back!

[delineator]

Restarted, got some BSOD, and other weird issues. Isolated each gpu and got different results:

I think I'll try a clean install of hte drivers and will report back

[delineator]

Did clean install, same result.

[savage309]

As it happens even on empty scenes, it must be a setup issue.
Best to write to support@chaosgroup.com - there might be able to help you to track it down. There are plenty of things that should be tried, by going back and forth in the forum might take a while.

Best,
Blago.

Wait hold on, I never said it happens on empty scenes -

this is each 1 empty scene rendered on a single card each time

[delineator]

Eliminated some variables, and finally ended up resetting the settings and working with a clean scene and bringing the model in, and now everything is up and running. I"m not sure what the issue is or was, but there was something it didn't like. Able to render on both simultaneously and my TR1950X for a slight render boost. thanks!

[savage309]

If it happen again, please send us the scene.

Best,
Blago.
