Check what does - Check OpenGL suppor says:
I've got a 960 and it works fine with Lightroom with the Graphics Processor option enabled. Personally, I wouldn't bet on the driver being up-to-date if it was pre-installed by Dell as part of a software build. Best to check for yourself, you can use the Nvidia GeForce Experience software to check for updates or go to the Nvidia web-site to check.
Thanks Jim. I updated the driver using the GeForce software but I still get the blue screening with GL switched on. It strikes me as very odd that earlier phots are not affected so I wonder whether it is something to do with using a later Nikon camera. I guess we will never know!.
Again many thanks.
