Yeah, without knowing how those preference knobs are handled internally or mass-editing artists' preferences files, the node-level solution definitely makes more sense.

Marten,
Yup, that works fine, disables all of the GPU enabled nodes. Will
require the artists to manually enable all of the nodes which makes
them aware that they will be using the GPU.

Nathan,
Thanks for looking, a work around would be to set the value and
re-save out the file which is a bit too much of a work around,
disabling all of the nodes by default is good enough for me.

Cheers,
Josh

Hmm, that's an interesting one. It looks like Nuke is actually storing
'selectedGPUDeviceName' in the preferences file rather than
'selectedGPUDeviceIndex', and there's also a 'selectedGPUDeviceNum' knob on
the preferences node.

However, regardless of the knob default combinations I've tried (including setting both), I can't get it to default to 'Use CPU', even after removing my preferences entry for that value and swapping the Preferences class into the knobDefault calls. I could be overlooking something else, but it seems
like the logic for this preference is handled differently than other
preferences/defaults.

Hi,

Is there is an easy way to disable them by default as we're running
into some issues.

using nuke.knobDefault('preferences.selectedGPUDeviceIndex', 'Use
CPU') doesn't seem to work.

thanks,
Josh
