No Graphics Acceleration v8.4

I just upgraded from LR 8.3.1 to 8.4 and support for my Graphics Card acceleration seems to have disappeared. I'm sure it was working under previous version but under Edit/Preferences/Performance, the graphics acceleration is now marked as "off" with a message that my system isn't supported. Checking out the list of Graphics cards it seems that my GeForce GTX 750ti card is now no longer supported by latest LR version. So, the promised improvements in perofmance that I've been waiting for aren't available to me unless I shell out for a new card - unless of course any helpful soul on here can point me in the right direction please? It's also worth noting that the graphics card IS supported in the latest version of Photoshop CC.

My laptop GPU (NVIDIA Quadro 1000M) was detected by LR 8.3.1. It should at least be recognized by LR CC 8.4 and be usable in basic mode/for display, right? Can I expect a fix for this? The latest driver for my GPU is version 377.83. I already opened the laptop to check if the GPU is replaceable (as with other business laptops) but in my case it is soldered to the mainboard.

In the performance tab of preferences, what is stated as current status of GPU acceleration?

Disabled?

Basic?

Full?

Also, what is your OS?

My status is Disabled, OS is Windows 10. The card is not detected - though it is in LR 8.3.1. The recommended graphics card on the FAQ page is one architecture step later than mine (GTX 760 is Kepler, Quadro 1000M is Fermi). Still it both supports OpenGL 3.3 and DirectX 12.

One thing that is missing, one little tidbit as to previous version of Lightroom accepting Graphics Acceleration for various cards is that Adobe has tightened up the inspection by Lightroom for GPU compatability.

Cards that supposidly worked for the simpiler Graphic Processing acceleration. May not work for the more aggressive use of the GPU in v8.4

And, it looks like, Adobe did some testing, found issues with older cards, did not solve the issues (at least yet) and included them (apparently not documented to public) as vebotten in LR

So the new version is more pickey. Remeber that turning use of Grphics Processing off used to be (in v 8.3.1 in fact) a common diagnostic for when things go wrong, as in not all GPU's are equal despite LR allowing your card.

Also, some cards might still work for what they are calling BASIC use, but not full, and if your card just gets BASIC and you are not running high def, why use this option? Over at the feedback site, on userr got an artifact, turning this option off fixed, so still an issue with some GPU's

P.S. see the Feedback page, some problems posted:

I've gone and disabled GPU switching in the BIOS since it looked like it was seeing only the intel GPU and not the NVIDIA GPU even though the NVIDA was configured to be the GPU for all the Adobe apps. Right now PS does see and use the GPU but photoshop and ACR do not!!! LR doesn't even see the GPU as existing

Another interesting reply because Photoshop sees my Graphics card and I am able to use the Graphics processor, but Lightroom, same as you, doesn't see it.

I can only say that it was working before 8.4 and doesn't now, irrespecetive of the fact that I had an older driver installed - that's a red herring and I've installed the new one now anyway. I'm not savvy enough to fiddle in the BIOS but all I know is that I had something working and Adobe seem to have helped disabled it on the latest update.

Photoshop and Lightroom might as well be Apple and Oranges. How the GPU is used in PS has no relation to use in LR

To all members noting that this option is shown in preferences as OFF

Read the Adobe GPU Troubleshooting and FAQ web page, it has been updated:

Adobe Lightroom GPU Troubleshooting and FAQ

If LR no longer thinks your GPU is capable it now defaults to off, as opposed to Auto (and you can also select Custom)

From that page (emphasis mine) :

________________________________

GPU acceleration in Lightroom Classic

Introduced in Lightroom Classic 8.4 (August 2019 release)

In Lightroom Classic, the current status of GPU acceleration is displayed just below the GPU name. Your system may automatically support basic or full acceleration. If your system automatically supports basic acceleration, you can enable full acceleration using the Custom option.

Acceleration may also be turned off automatically if your system does not support it or due to an error. If acceleration is turned off and an error message appears, it could be due to GPU hardware, driver version, or operating system not meeting the system requirements.

You can select one of the following options from the Use Graphics Processor drop-down to turn the GPU acceleration on/off.

Auto

Select this option to automatically determine the correct level of GPU support based on your system's hardware and operating system configuration. This is the default option.

Custom

Select this option to choose the level of GPU support manually.

Use GPU for Display

Use GPU for Image Processing

Off

Select this option to turn off the GPU acceleration.

Good, I see that you have posted your issue at the official feedback web site, and that you are engaged with some actual Adobe Techs.

Lightroom Classic 8.4: GeForce GTX 750ti - Graphics Card not supported | Photoshop Family Customer Community

Foe in some reason, your system information is easier to read at that posting.

I notice that OpenGL failed and no mention of DirectX.

Did the Adobe techs address that?

See solution 3 in the following, but cross fingers it does not make things worse, if still in contact with Adobe, ask them about it:

Adobe Lightroom GPU Troubleshooting and FAQ

and this link link to revert back, if it crashes:

Hi David, no mention of the DirectX issue by the feedback website but another preson has reported a similar problem. I'll check the link you sent me thank you. I have also downloaded the newer driver that you listed and have created a restore poiint so may try to install that to see if it works.

Thanks again

I just looked at solution 3 you mentioned at when I checked down the folder tree, I could not find the Camera Raw GPU config .txt file in the folder - it was empty.
