I'd imagine there's an issue with your GPU driver take a look here
You may need to download the latest driver for your GPU from here
Also take a look at this thread and see if it helps, you need to add Photoshop to the 3D settings in the Nvidia control panel
I was to lazy to do up screenshots again so take a look at my reply, hopefully that will help
It's true....the older I get, the stupider I get..... Yeah, uninstall, update drivers, reinstall........

No worries, glad I could help
