VRay 5 for Mac trial - does unsupported enabling of GPU still work, with the trial?

[chronopsis]

Testing out V-Ray 5 with Maya on Mac. I have been using V-Ray NEXT with GPU enabled, works with Nvidia Titan X.

Does the (unsupported) GPU enabling still work with V-Ray 5? I already have the Maya.env variable set, but there seems to be no "vray_gpu_device_select" available in the bin folder.

Hello chronopsis

VRAY_MAC_GPU will show V-Ray GPU in Maya, and you will be able to see device selection
Are you using a Titan X under High Sierra for this? we don't offer support for this anymore
The drivers are very old and you will most likely run into issues, this is on Apple as you probably know
The way of using V-Ray GPU in Mac OS now is Cuda mode on CPU

Best,

Thank you, Muhammed,
Good to know. On my system it only shows CPU for device selection.

So it allows one to select "V-Ray GPU" for renderering, but then doesn't actually use the GPU (and renders are very slow/low quality).

Quality should be the same, but yeah you are using the GPU code on your CPU(it is what we call Hybrid rendering in V-Ray). It will be much slower than your Titan X
I used to do GPU rendering with V-Ray Next GPU and Maya a few years back. I had a machine with 3x 1080Tis, worked nicely until issues happened between Apple and Nvidia then I migrated to Windows

No other workarounds for now I'm afraid
