Use GPU for image processing is Greyed out even though minimum specs are met (RTX 4080)

I am using an Nvidia 4080 on Win11 pro. All drivers and software up to date.

I have no idea why Lightroom sees it as windows 10 business. It's windows 11 pro. Regardless, the card obviously blows the system requirements out of the water. Any idea why I can't use this new, 1200$ card for full acceleration?

Correct answer Ian Lyons

Typically, the issue you're experiencing is due to the GPU crad drivers, and more recent drivers from Nvidia seem to be particularly problematic. So, checking an earlier version may be worth a shot. However, before going to that length you should first check that the issue isn't due to the GPU test carried out when LrC is launched failing. The steps are as set out below.

Quit Lightroom Classic.
Locate the Camera Raw GPU Config.txt file.
- (macOS) /Users/[user name]/Library/Application Support/Adobe/CameraRaw/GPU/Adobe Photoshop Lightroom Classic/Camera Raw GPU Config.txt
- (Windows) \Users\[user name]\AppData\Roaming\Adobe\CameraRaw\GPU\Adobe Photoshop Lightroom Classic\Camera Raw GPU Config.txt
The user Library folder is hidden by default in macOS X 10.7 and later releases. Use the directions here.
Manually delete the Camera Raw GPU Config.txt file.
Relaunch Lightroom Classic.

It's a LR bug -- LR is tripping over Windows' "as designed" behavior. See here for details:

To build on Ian's reply, after deleting the Config.txt file, update to the most recent version of the Nvidia Studio Driver, 531.41 (you're on 531.18), which claims in its Fixed Bugs:

Adobe application stability issues using 531.18 [4008751]

Also as any fyi to anyone that comes across it, the newest game ready driver also worked.

LrC Sys Info stating Windows 10 not 11 is an oddity at Windows OS and does not cause issues other than being annoying.

Ok. I've chosen to stay at 10 for now so I wouldn't know.

In your system info you did not show the gpu info, can you post that? (does it show DirectX in use)

Do you have more than one GPU installed (not referring to an integrated video control, but an actual card)

Do you use a third party GPU accelerator?

And, somewhere in the community, someone had a similar issue, might have related to Export, and they were instructed to (with LrC closed) delete two files, then restart, but dang if I cannot find it.
