Photoshop CC 2021 Drawing Mode issue

I have noticed that Photoshop has been running noticeably slower to open and close recently. I checked my preferences for performance and discovered that the "Normal" and "Advanced" drawing modes are not available now. Only Basic. I have an NVIDIA Ge Force GTX 1660 graphics card. I updated the driver today. I'm using that card as my preferred card for Photoshop. Memory usage is set for 70%. I have 16 GB of RAM available. 3 scratch disks assigned. I've tried everything I know to optimize Photoshop but I'm stumped on this one. As far as I know my graphics card is sufficient for Photoshop but I can't get above "Basic" settings in preferences. The other 2 modes are not available. If anyone has any suggestions I would be most grateful. All of the graphics modes have been available in the past. I'm wondering if something has changed with one of the recent updates to Photoshop. I've had problems in the past with bugs in Photoshop updates. Thanks for your help.
