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.

These GPU acceleration feature requirements for Camera Raw 11.4 also apply to Lightroom Classic 8.4:

Camera Raw system requirements

The OS and driver version and not just the card model are considerations.

I may be able to shed some more light on the problem if you can share some log files for Lr Classic.

In the Logs folder (see instructions below) you should find log files with names beginning with Adobe Photoshop Lightroom Classic Log Latest." The v1 log file might be helpful.

Here are some generic instructions for finding these logs:

Collect Logs

IMPORTANT: You must QUIT the host application BEFORE you collect the log files.

The best way to collect a log about a bug is to.

Quit the host app.

Re-launch the host app.

Perform the minimum number of steps required to reproduce the problem.

Quit the host app again.

Now collect the log files.

On Windows the log location is:

%APPDATA%\Adobe\CameraRaw\Logs

One shortcut to get to this folder on Windows is to...

Tap the Windows key

Enter "Run"

Enter "%APPDATA%\Adobe\CameraRaw\Logs"

For example:

C:\Users\tester\AppData\Roaming\Adobe\CameraRaw\Logs

On Mac the log location is:

~/Library/Application Support/Adobe/CameraRaw

For example:

/Users/tester/Library/Application Support/Adobe/CameraRaw

Please report your Lightroom>Help>System Info...

And try to follow Lr 8.4 instructions in this FAQ https://helpx.adobe.com/lightroom-classic/kb/lightroom-gpu-faq.html to update your GPU driver from Nvidia.

For some reason your GPU has been blacklisted by Adobe Lr / ACR team. There's nothing anyone on this forum can do to change that. Best you raise the issue at Lightroom Classic | Photoshop Family Customer Community The engineering team and/or QE visit that forum.

This GPU is not on a blacklist in 8.4 for Windows.
