Mac OS and RT ( CUDA freezes maya )

[joa_grilo]

Hi!

Because i'm running on MacOs I always had problems with the RT.
I love it using it on windows, but at work its really hard to get fast results.

Currently using CPU is being a good solution, its faster than not having any kind of RT.

I need to kill the service time to time, because it jams sometimes.

Using CUDA is currently working, but it just freezes the workstation, every time a make a change

The specs of the machine are on the image.

I would love to have a easy RT CUDA on Mac.

The Open CL doesn't work on my machine.

V-ray 3.10.01

What version of Maya do you have ?
Can you please try to go into System Preferences / NVidia Driver Manager and check what version is your driver ?

When the machine freezes, do you have to reopen Maya, restart the OS or it just freezes for some time ?

Maya 2016 sP1
CUDA Driver Version: 7.0.64

Its freezes Maya, if I press ESC and wait it return to normal, but if I try to change anything in maya, it freezes .

This is strange. Does it happen with every scene ?
Also, could you please try changing the values of RT Bundles size to 32 and Rays Per Pixel to 1 in the V-Ray RT Settings tab ?

V-Ray RT starts as an external process, which is a console/terminal. Can you check what does it says when it freezes ?

If this doesn't help, you should probably write to support@chaosgroup.com to see if they can arrange remote session.

I will try in in different scenes.
I will return with some answers after one or 2 scenes.

Playing a bit with the settings I was able not to freeze Maya, but CPU its still faster than CUDA....

NVIDIA GeForce GTX 760 4095 MB

It depends on the CPU, the scenes and the way you measure the performance.
If you can share the scene, we can give you hints on what is going on.
