Hello all,
I'm trying to test my system with 8 GPUs. When I go to preferences>CUDA devices the option to add additional devices is greyed out. I have 1 active device and 7 inactive. Any thoughts? I'm wondering if it is a CUDA driver version issue perhaps.

Thanks

What version of Octane are you using?

hello,
i switched over to beta 2.46b and everything seems to be working fine including proper performance scaling across all the gpus.

thanks

In this version you can only enable and disable GPUs after starting Octane, before starting to render anything.
