Lrc suddenly does not see my graphics card as meeting Lrc requirements, so Lrc disabled using it.

[axrtu]

Hello, Lrc v. 13.5.1 Win 10. 

I was happily working for about 3 hours in Lrc yesterday when the develop sliders started being very unresponsive.  I Googled the problem and the first suggestion was to disable my graphics card.   The setting was turned off whth a message  "Graphics processor acceleration is not supported by your system". 

I always have my graphics card enabled.  My graphics card is a Nvidia RTX A2000 which does fit the Lrc requirement.  I then opened Lr and it shows my graphics card and all of the adjustment sliders work perfectly, same thing for Ps.

I then reset my preferences thinking that might solve the problem but it did not.

I hope someone might have the answer.  Lrc is really unuseable at this point.

Thank you so much!

Tom

Have you tried restarting your Windows PC? Not a shutdown, but a Restart.

Yes, I have done both. I restart and a complete shutdown and neither worked.

When googling, did you see this one:

And while that does address disabling the use GPU, that is as a diagnostic.

Instead, (in addition to reading that link) look at the part Solution 3. specifically the part about locating the Camera Raw GPU Config.txt file, and manually deleting it. This to force LrC to reconsider the GPU upon startup

Someone else recently had this same graphics card Nvidia RTX A2000 and got the same message as you did. I don't know if an answer was found. Please search this forum for other messages mentioning this graphics card.
