Lightroom Classic does not recognize RTX 5080 – GPU support missing?

[Hannø]

Hi everyone,

I recently upgraded my system with an NVIDIA RTX 5080 (Desktop GPU). While Photoshop detects and uses the GPU without issues, Lightroom Classic (v14.3.1) shows the “Use Graphics Processor” option as permanently grayed out.

I went through all standard troubleshooting steps, including:
– Studio driver 576.52 (clean install)
– BIOS set to PCIe, iGPU disabled
– Preferences reset, admin launch, full Creative Cloud reinstall
– GPU correctly assigned in Windows and in NVIDIA settings

I also spent over 2 hours in Adobe Remote Support (case ADB-40345402-L1L2) with no solution. The agent could not confirm whether the RTX 5080 is officially supported in Lightroom Classic. The case was closed without follow-up.

So my question is simple:
👉 Is the RTX 5080 currently supported by Lightroom Classic?
👉 If not, when can support be expected?

Thanks in advance for any clarity!

1. Try deleting the Camera Raw GPU Config.txt file, following steps 2 - 5 of this article:

2. Delete any TempDisableGPU2 or TempDisableGPU3 files. Read the instrructions carefully about the Lightroom Classic subfolder:

3. If these steps don't help, do the LR menu command Help > System Info and copy/paste the entire contents here so we can see exactly which versions of hardware and software LR thinks you're running and important LR options that are set.

Thanks so much, that did the trick!
Deleting the Camera Raw GPU Config.txt file resolved the issue – after restarting Lightroom Classic, my RTX 5080 was finally recognized and GPU acceleration is now active.

Really appreciate your help – this solved what multiple hours of official support couldn't.
Hopefully Adobe improves their first-level GPU support in the future.
