Does this happen in smaller files? Maybe with just one or a couple of plages? Can you share a LayOut file so we can try it with other hardware to see what we get?
I’m glad you have a solution. It’s interesting to me that this happens with the new graphics engine with the graphics card you list. I sure wouldn’t expect that.
@adam might be interested in this. And maybe it’s an issue with the current graphics drivers from nVidia. Might make sense to keep an eye open for updates and test periodically when nVidia does update their drivers.
Might also be something stupid like you just need to do a power off reboot.
My machine did freeze up during a SketchUp render and I had to reboot. But it’s specifically the experimental graphics engine option. Turning it off brings back the problem.
Just to add more data to the issue, it might be because I’m running 3 monitors: two connected to my Nvidia card and a smaller HD monitor connected to my Intel graphics port.
