P: Enhance Details broken - All-black preview and final render

I was super excited about the new Enhance Details feature rolling out today.  However, something about it refuses to work for me.  When I select the feature on an image, the preview pane only shows a completely black pane on the "Enhanced" version.  Furthermore, when I click the "Enhance" button, processor and GPU rev up and the progress bar moves, but ultimately it only renders a completely black DNG.  This seems to happen on any photo in my collection.  I have verified that I am updated to the correct version of windows, and that I am working on a CR2 RAW file.  Screenshots:

Hello SImon
 - It appears that the problem lies not with the driver but with the differences between Open GL and Direct X. I have forced the Open GL but have not disabled the Graphics processing and it seems to work. Am I missing something?

Thanks Wes, it finally worked after finding the right folder to drop config.lua in. AGAIN THANKS

Conferred with my colleague, Wes Aslin's workaround above (do a clean install of the vendor's latest graphics driver and forcing Lr to run the OpenGL path for interactive edits and relaunch Lr) would be a short term workaround for evaluating the enhance details, but the fundamental GPU driver's issues remain. What happens is that when you disable the DirectX, Lr computes the enhance details on the CPU instead of via the GPU acceleration. That is why it works, but it will be slow.

We are working with Microsoft and Nvidia to get the driver issues resolved. Please stay tuned.

Interesting. Do you mean the enhanced details is working for you now after forcing Lr to prefer OpenGL to DirectX?

For Adobe's purposes attached is my DxDiag file where extended detail works with both "use graphics processor" selected or unchecked.

Thank you Wes Aslin.  I had previously used the config.lua fix to solve another plugin problem.  Apparently, the lua file has been recently updated because when I downloaded the link the post on this thread and turned off the "use graphics processor" switch, the extended detail is working fine, quickly and the dng file is generated and is viewable.  Thanks Wes.

P.S.  Wes, with the new config.lua file in the Lightroom directory, the extended detail works with the "use graphics processor" checked or unchecked.

Thanks Wes! The workaround worked and finally exciting "Enahnced DNG" feature can be checked. Honestly the result less exciting - playing with comparing in a preview got stacked LR, so need to kill a process. Comparing enhanced picture of a random portrait with manually processed I should admit "enhancement" loosing much - a skin looks too rough, eyes too contrast. So far overall expression not too much optimistic, continue valuation...

Same black image problem on two different computers with latest drivers, looks like Adobe released this feature before ready to market.
