Lightroom: Soft Proofing does not work when 'Graphics Acceleration' is enabled.

Soft Proofing works fine - except when 'Graphics Acceleration' is enabled.

With graphics acceleration on, view /  soft proofing / show proof results in error:  Unexpected error performing command: AgGPUPort.redraw exception thrown

With graphics acceleration off, no error and soft proof is displayed.

Windows 64 10 V 1511, August updates; Lightroom 6.6.1; Nvidia Gforce GTX 860M/PCIe/SSE2  Version 3.3.0 driver 372.70.

I'm starting new project and soft proofing would be very helpful...  I can run w/o GPU acceleration, but it does slow down noticeably.  Is there any setting I'm missing or a workaround?

Thanks!

You could try rolling back the graphics card driver by a month or two. I've seen another issue today that was solved by going back a couple of months.

Thanks for the suggestion, but I had been running the 368 driver and updated to the current 372 in an attempt to fix this before I posted....  with no effect...

Hi Harper,

What settings and profile do you have selected under Soft Proofing? Do you have more than one graphics card in this system? More than one monitor? Trying to gather some more clues for our engineers to repro.

A copy of the ICC color profile would help too.

I'm not that certain what you mean by settings in 'Soft Proofing' 

I I've tried several profiles: The Blurb_ICC_Profile.icc ( From the blurb website ) ; ProPhotoRGB; and EPSON Standard RGB Gamma 1.8.  All result in the same problem.  I don't know how to send a copy.. let me know if you still want one and how to proceed.

Also - sometimes I don't get the error message given above - sometime the image goes white and unresponsive.

The reaming settings don't matter either - I've tried changing gamut warnings, intent and paper /Ink simulation with no effect.

I'm running on a laptop, using both laptop screen and an external monitor, with only one graphics card.  The problem is unchanged independent of screen used.  ( I've only tried to debug with one Lightroom screen )

I have tried various locations for the profile files.  I currently have the Blurb profile in c:\Users\Username\AppData\Roaming\Adobe\Lightroom;

The other profiles are in c:\WIndows\Systems32\spool\drivers\color

I sort of think part of the issue is profile installation, location or system setting, but I can get profiles to appear in the pull down for profile in the soft proof portion of the develop module, so LIghtroom can at least find the ones I care about....  And when I do get this to run without GPU acceleration, the profile does not produce as much change in the proof as I would expect, but that's hard to quantify??

Thanks for the help.

On another thread, a customer reported issues with recent drivers. You could try rolling your driver to the previous version 368.81. To rollback, go to Device Manager> Display Adapters & right click on Nvidia & select Properties, then click on Rollback Driver.

See the earlier post. I was running the 368 driver when I first encountered this problem, and only moved to current driver as part of my own debugging before I posted here.  No change between the two drivers, so I'll stay at the current one lacking more info.

I'm suspicious that the problem lies somewhere in Windows 10 color management and proper installation of the profiles, but I haven't been able to decode the MS support on this and, don't really have the proper knowledge to do so.  Any suggestions are appreciated.
