I have a Dell t7400 with 16 gigs of RAM and the Quadro 5600 graphics card. I have been working well for months and today the CPU is going from 15% to 100% when I am working with SW and rendering with PV360. When rendering it should be at 100% as normal but today it is going between 15% and 100% but mostly at 15%.
I do have Modo 501 + SW add in kit and there are no CPU problems it is consistently at 100%.
The only different thing today was a MS Windows update notification. The problem was seen before the update and after. I have even restarted twice.
It looks like it could be isolated to a specific assembly that I made with a master environment assembly (with a back drop and lights) and added another assembly to it for rendering. All individual files open and render fine but this one final assembly for rendering.
Any suggestions?
