Not sure if this is an nVidia driver issue, but Houdini is crashing several times an hour on me.

Mac OSX 10.12.3 on a Mac Pro Mid 2010 with dual Hex Core and 80GB of RAM.

Running the latest nVidia Web Driver.

Any suggestions?

Yes - the non-standard macOS Nvidia cards crash a lot with openGL errors. Perhaps post a crash log so we can check. If you boot into Linux/windows you'll find a lot better experience.

The logs are in /tmp/houdini_temp/

Ok, sure. But, I have never been able to find the /tmp/houdini_temp/ folder anywhere.
Where is it located?

In Finder, the ‘Go’ menu has ‘Go to Folder’

Thanks - that's the normal GL crash you get on MacOs, which unfortunately makes the new Titan Xp out of the question for MacOs too.

Worth trying H16.0.618+. There was an optimisation to the UI memory usage that /*appears*/ to have helped so far.

@reel…. what card are you using? Looks like the 1080Ti is very stable, no GL crashes, at least for a day so far.
