The same is happening here as well, GTX 560Ti 1GB (in all GL modes. Fine in H11 mode)

Other people have reported such happenings and it seems to be down to the openGL within Houdini.

If it matter's I'm seeing the same thing - just got a new Quadro 4000 card, and the latest Windows 7 drivers. Bummer
I do now have the option of selecting OpenGL 3.2 for the viewport (which I've selected and restarted Houdini 12), but no lucking getting the Advanced lighting to work.

This is from the Help dialog:

Platform: windows-x86_64-cl15
OpenGL Vendor: NVIDIA Corporation
OpenGL Renderer: Quadro 4000/PCIe/SSE2
OpenGL Version: 4.2.0
OpenGL Shading Language: 4.20 NVIDIA via Cg compiler
Detected: NVidia Professional

I would like to ask for an update of all of you guys

For me, nothing changed here with the new production build update for houdini 12 where they said they had furthermore improved the viewport. Is that right? What about your systems guys? Working now when switching to HQ or still broken?

SideFx, please fix this. It has been a very cool feature in H11 where it worked perfectly. You promised a “enhanced viewport” in H12 but all I see is either a mess, or nothing, or blackness, or white objects as soon as I try to use advanced vieport features.

Hope you guys at sidefx manage to fix this! It would be great!

which one in particular? Just to clarify and have something to compare to.

EDIT: just tried the new daily build and it is still broken. I've written a support request to SideFx. Now waiting for their reply.
