I'm using GeForce GTX770M display adapter on Gigabyte P25 Laptop. My Photoshop is acting strange. I think the problem is about the laptops 2 video display adapters. In the Performance tab of the Preferences I see Intel Graphic Processor is selected. I think Photoshop can't detect GeForce GTX.
My problem is that some tools are really slow. And whenever I want to export the frame animation I made (I tried everything) Photoshop screen freezes. Today I waited 30 minutes and render window opened but it froze as soon as I clicked the render button.
