It's a laptop with two video cards. It's supposed to be using the Nvidia card but I just realized that it not.
In Nvidia settings, Nvidia is chosen for both default and specifically for Chief. In CA preferences/video card status, it used to show the Nvidia card but now it is showing the Intel card. So something is obviously not functioning. The only place I know to change it is the NVidia panel. Since it isn't using what is set there, does that mean the card is kaput? Nothing looks wrong in device manager.
Just after I posted the problem today I got an error message and had to close CA. It was an MS visual C++ Runtime library error window that said "Runtime error, Program: (the CA file I was in) R6025 -pure virtual function call", After reopening CA the dimension on the section looked fine for a few minutes.
Thanks for any suggestions.
