I know that i have the 'smooth wire shaded' toggled on. But as soon as i 'create' the cube, it goes invisible.

I am having the same issue, 18.5 works fine.

Nvidia drivers - rollback

Check the Drivers section at the end

I followed all the compatibility items and made sure everything at least matched the minimum requirements. I was able to see the geometry ok, and play with some of the features. Not in a fast way, but that's because I just hit minimum standards. Not a SideFX issue. Later I went to open it back up and it crashes. A lot of windows cant do this and that. I will roll my laptop back to 18.5 and just use 19 on my home desktop until my company replaced my laptop. Since I don't use Houdini other then a hobby. I think I can block out my stuff with 18.5 when I'm on the road, then assemble it when I get home. Thanks for the reply pointing out why no geometry shows.
