Photoshop not recognizing GPU (Nvidia RTX 2060 Max q) says it's found an error in my display driver

That surprises me, as the pattern with V22.3.1 video card problems has been mainly with older cards. 

What driver version are you using?  Is one of those Game Ready drivers?  I have an RTX2070 and I actually have slightly more functionality V22.3.1 than I did with V22.3.  I was unable to turn on OpenCL with the previous version, and the Drawing mode option was limited to Basic.  You can see that I _seem_ to be able to chose Advanced now, but it will fail back to Basic if I try and do anything with it.

IIt's intensely frustrating as so many of Photoshops advanced features need the GPU, and are not working for an awful lot of people right now.  If anything, V22.3.1 has made a bad situation worse, and was obviously rushed, so I suspect they won't risk another update until they are sure they have fixed things.  Mean while we have to either roll back, wait for an update, or live with it. 

It's a known problem. There are several posts here and in the bug forum.
