Since the latest LR and PS updates my Nvidia GeForce 770 GPU is said to be unsupported in LR while it is still supported in PS. Here are the pertinent sections of the system information from both programs:

The GeForce 770 GPU is OpenGL compliant and supports most, if not all DirectX 12 functionality, depending on the reference source. I've seen a lot of chatter regarding GPU support or lack thereof since the last LR update. I'm posting this information with the hope that it will illuminate or help resolve some of the issues surrounding GPU support in LR.

Windows 7 does not support DirectX 12. While your video card may support this, your Operating System does not. You should be able to obtain full functionality by upgrading Windows to 10. 

Photoshop and Lightroom have different GPU requirements. However, the Camera Raw plugin and Lightroom share GPU requirements.  For full functionality in the Camera Raw Plugin and Lightroom you need a greater spec than is required for other aspects of Photoshop.

Thanks for your comments Rick. I was aware of the fact that Win 7 does not support DirectX 12. The GeForce 770 worked with previous versions of LR. So with the latest release Adobe must have removed DirectX 11 support and/or increased the OpenGL requirements without informing its customers. A little more transparency might have help reduce the high level of confusion as noted on this forum by all the posts on this topic.

Alas, I will be upgrading to Win 10 later this year. It is uncertain until then as to whether I will also need to upgrade my GPU.

Thanks again.
