Does your graphics card match the requirements for tested cards in this article? Photoshop system requirements
If so, then you may need to update your GPU driver. If not, you can still try the driver, but you may find it may not work. Or it might! My graphics cards (neither of them) is listed on the page, but they both have the most updated drivers and they both do great with Photoshops's GPU settings. Although, one has 1GB gpu ram, and one has 4GB.
I guess the main question is... what graphics card are you using?
I said that in my question: Intel HD Graphics.
That's a family of integrated graphics controllers (not actually cards), what is the specific one and hiw much VRAM is there? Seems unlikely it will meet requirements though. Serious users often have $1000+ graphics cards.
I have the basic Graphics of Intel HD Graphics, so it doesn't have a specific number:
It worked in the past in Photoshop, but someday Photoshop could not recognize this Graphics Processor.
So I can't work in Photoshop with the Graphics Processor because I can't check "Use Graphics Processor".
And I have 1,696 MB of VRAM (as I had when Photoshop allowed me to use the graphics processor in it).
Maybe your card is unsupported by Photoshop CC
