Redshift3D rendering by eGPU?
I have a MBP 2015 + amd dGPU, and I just want to use the egpu for gpu rendering (redshift3D) but with no external display. Has anyone tried this setup, or a similar one, with success? I mean, not using an external monitor. Does one have to force the internal display to use the eGPU? or does the dGPU will be enough for internal display and still it will display the redshift materials and rendering? (I think Octane has works the same way as redshift)
I'm not worried about hot-unplugging for now, nor with choosing the right nvidia drivers, I believe I can manage that when the time comes.
I've just asked a similar question about using it for Vray RT in the same way. i.e. without connecting an external monitor. please let me know if you find out if this works or not, and if you find anyone who has had success in doing it.
Pretty sure Redshift requires CUDA and an Nvidia GPU - it’s not compatible with AMd GPUs whatsoever it would seem.
Currently I am testing the Sonnet 350w eGPU chassis with a base model iMac pro and an Nvidia GTX 1060 3GB and I’m not having a good time so far (and I was intending to test with RedShift and VRAY for C4D R18.048) but it seems I have to boot without my Sonnet chassis plugged into - TB3 port on my iMac Pro.
Also there is only a workaround to allow an egpu to power the internal display as well as an external display.
After running the recommended curl script for 10.13.4 posted in another sub forum I encounter this screen after booting with no eGPU: a black background with a green progress bar and a cyan Apple logo - the eGPU causes this behavior and the cursor then freezes within the iMac Pro screen. I can reproduce this by booting up without the Sonnet eGPU chassis, login to my local admin account, log out, plugin eGPU.
Starting up with the eGPU connected and with an HDMI cable from my GTX 1060 3GB to an external Samsung 1920x1080 display is even worse. In this particular order, one sees a blurred High Sierra login screen and a blank black display regarding the iMac Pro with the cursor not visible anywhere.
Has as anyone had success with this?
I just attempted erasing and re installing and encountered the same behaviors as before. Allowing the iMac to startup up by itself it hangs on the black background in the iMac and also x
I'm not sure this is stable enough to use with Nvidia GPUs at least in a production environment that depends on CUDA support.
Yeah I ended up returning the IMac Pro because it had a defect related to the VHB strips not allowing the display glass to lay flush with the unibody aluminum body edge - no loss since Nvidia eGPU support is bunk at this time for a production workflow. PCs it is or 4,1 Best MAC Pro if my ADs need a Mac or die hahah.
