I. where do I find that?

D. What's your driver version? Numbers are not known by me

Also post bugreport.zip, it's required.

Driver is that what it says, and Windows says I have the best drivers it can find

maxon folder "_bugreports" is empty. I'dont get bug report, when C4D starts new.

Hi,
the Nvidia driver should be good, Studio 431.86, please post a screenshot of c4doctane Settings/Devices panel, and another one similar to this: ciao Beppe

oh, i fount the driver: it's 431.86. I see, there is a new one 441.28, shoult I install it?

Please, download and run GPU-Z:

And share a screenshot from the Graphics Card tabs from both GPUs, thanks.
If it crashes with Tonemapping active, probably the PCI bus of the second GPU is too slow.
Please also post a screenshot from c4doctane settings/Devices panel, thanks.

Hi Beppe

here some screenshots, thanks a lot!

Please, try theses steps.

• Go to Nvidia Control panel, menu Help, and enable the Debug Mode, to work with GPUs at default clock.
• Connect one monitor per GPU, to reduce the available VRAM more uniformly .
• In Devices panel, enable the Priority for both GPUs, and set the Priority popup to LOW

ciao Beppe

nop.
But actually, I don't need "Use for tonemap" for both GPU, so I break up to test stuff...
