Photoshop CC 2015.5: Does the latest PS have the ability (or need) for CUDA?

I'm trying to see if my GPU is not allowing it for some reason or if it's just not available still in PS. I would think the addition of 3D would bring in the CUDA support but I don't know so I'm asking.

My PS System Info shows: clgpu[0].CUDASupported=0.

As far as I know PS hasn't ever had CUDA support but if you look at this Adobe Forum post Photoshop won't detect nvidia GPU! this guy's report shows clgpu[0].CUDASupported=1.

Just want to know if my card needs some attention.

Photoshop 2015.5
NVIDIA GeForce GTX TITAN X, 12 GB
Mac Pro (12-core) on 10.11.6

Anyone? I keep coming across other logs that show clgpu[0].CUDASupported=1. Still have clgpu[0].CUDASupported=0 on mine.

Photoshop doesn't use CUDA, but it does use OpenGL and OpenCL directly for 3D and other features.

OK this is what I thought. Do you know why various System Info (from Photoshop) logs across this forum and others show a 1 for CUDA support? Am I interpreting something wrong in the way Abode logs items are listed?

If you could just answer quite directly please, what does this item tell you?

Photoshop runs a small program (GPUsniffer) on launch to test the graphics card and driver for compatibility and disable the card for the app if there's a problem or enable Graphics Acceleration if it is available. Adobe's DVA team originally created the GPU and the digital video apps do use CUDA. The output of that line is a result of a test that DVA apps perform and tells them whether CUDA is available and will work with their implementation. Photoshop is only concerned if you have more than 512MB of dedicated VRAM, are using OpenGL 2.0 or later, and OpenCL 1.1 or higher.

Sincerely and without sarcasm this time - Cool, thanks for all the info there Jeffery. Think you knew where this was going and preemptively answered any follow-ups.
