Hello, Is there options to change which viewport Houdini 16 is using? We are trouble shooting Houdini becoming extremely sluggish after using the new copy SOP and I wanted to see if it was a view port issue. Its a scene where we are beveling stairs and copying them with rotation to make a staircase. Its only 10k polys and I have no idea what it would be so slow.

Specs
Intel i7-5930K 3.5 GHz
Nvidia 980 Ti
32 GB of RAM

Side note. The help browser has been sending some python errors and not working unless I restart houdini.

What NVidia driver version are you running? Many people have had problems with driver versions 376.xx, particularly since Windows 10 pushed an automatic update to that version in late December, and it has a number of problematic bugs in it. There's a new driver version 378.66 that you can download from NVidia's website that seems to fix the issue.

No, there is only a single viewport renderer (since H14). Most likely you're running 16.0.504, which has a few performance issues. Upgrading to 16.0.530 or higher will fix the issue (https://www.sidefx.com/download/daily-builds/). [sidefx.com]

Nvidia Drivers are up to date but we are running 16.0.504.20 so I will update and see if that will fix the issue!

Thank you so much! 16.0.533 has the scene running like a charm!
