Problems with Scrubby Zoom and Graphics Driver

I can't seem to use scrubby zoom.
When I have the zoom tool selected, the scrubby zoom option is grayed out and I can't click it. I know the fix for this is to make sure use Graphics Processor is selected in the performance settings, but that is grayed out too.
I have windows 10.
I have the NVIDA Studio Driver and I have made sure it's updated. Photoshop is updated too.
This problem came up before, and I updated everything, then it went away. It's back even after I made sure everything is updated.
Is there a setting in Windows that I need to change? Why doesn't Photoshop seem to recognize my driver?
