Neural Filters depend a lot on your Graphics processor. I had a problem with them, and had to turn OFF "Use Graphics Processor" under Preferences>Performance. For some reason, Adobe and Apple just don't always play nicely. You can also try adjusting the level of GPU support it uses, in that same dialog box, and see what works best. Please be aware... 3D functions are being limited and much of it is being removed in the most recent versions of Photoshop, so there may be glitches.
