OK, I see the "GPU" on the larger screen "Settings" but it's greyed out. Don't see "GPU" on the main (smaller) screen. I'm using a Dell laptop workstation and the Nvidia GPU is built on to the motherboard. Maybe that's why it's greyed out. The laptop is very high powered but I don't have the specs you're looking for (unless you can tell me exactly what you need and how to get it. Sorry. Guess I'll have to do without it. Thanks for the help.
