Camera Raw/Lightroom: Enhance Details broken - All-black preview and final render

From what I can tell so far, we're not dealing with a driver issue, though it seems to affect NVIDIA cards mostly (however not exclusively).

To help with our investigations, we'd like to collect some DXDiag logs. 

Here are some instructions:
Use the DirectX Diagnostic tool that comes with Windows called dxdiag. 

Basic instructions:

1. Use the Run command from the Start menu (Winkey + R)
2. Type dxdiag and press Enter
3. A small dialog will appear on the screen with some info.  If you press the Save All Information button you can save out a text file containing detailed information regarding the DirectX setup on the user's machine.
   1. 
4. If you could share the text files with me directly, email them to petgreen [at] adobe [dot] com. I'll pass them onto the engineering team.

Thank you!
Pete

Which video card are you using? What is the current driver version?

Hi, Rikk.  I'm using an nvidia 760.  Driver 416.81

Unfortunately, updating the drivers didn't solve the issue.

If you disable GPU in Preferences>Performance do you see a preview in the dialog?

Same thing happening to me, brand new HP EliteBook laptop. Does it in Camera Raw or Lightroom 

Do you see the same thing in Adobe Camera Raw as you do in Lightroom?

Could you try follow https://helpx.adobe.com/lightroom/kb/lightroom-gpu-faq.html to do a CLEAN driver install of the latest driver from the vendor to see if it helps.

I've run into the same problem. Lightroom Classic, MSFT Surface Book. Tried it with both Sony and Fuji RAW files. Same result. Both the preview and the final render are just black boxes. Completely useless.

Same here. Tried the Fuji sample, Canon CR2 full raw and a DNG file generated by LR. all BLACK

BTW I also tried rendering in LR and PS but same results.

If you haven't done it already, try follow https://helpx.adobe.com/lightroom/kb/lightroom-gpu-faq.html to do a CLEAN driver install of the latest driver from the vendor to see if it helps. And post post your Lightroom>Help>System Info... here please, thanks!
