Hoping to get some assistance here.
After a stage photography gig last night, I’m now sitting on about 1500 images to get through. It pushed me to finally look into why my setup has been struggling.
For a while now, Adobe Lightroom Classic just hasn’t been running like it used to. Editing feels sluggish, and once I get into Develop—especially with masks—it really starts to grind.
What’s frustrating is that it used to run smoothly on this same machine. Something has clearly changed, and I’m trying to figure out what.
In the Adobe Lightroom Classic System Info, I’m seeing GPUDeviceEnabled: false, which (as I understand it) means Lightroom isn’t actually using my 3080 Ti.
What’s confusing is that:
In Lightroom Preferences → Performance, “Use Graphics Processor” is set to Custom, and it reports “Full graphics acceleration is enabled”
When using intensive Tools like Mask, when I look in Task Manager > Performance: GPU Utilization is less than 10%
In the NVIDIA app, Lightroom is also set to use the GPU
So the UI says it’s enabled, but the System Info suggests it isn’t.
Troubleshooting so far:
Reset Lightroom config by renaming both:
AppData\Roaming\Adobe\Lightroom
AppData\Local\Adobe\Lightroom
Used Display Driver Uninstaller (DDU) to completely remove NVIDIA drivers, then reinstalled Studio drivers only
Reinstalled Lightroom Classic
Catalog is on C: (not in OneDrive)
Despite all that, GPUDeviceEnabled is still false and performance is poor.
Is there any good and realistic advice on fixing this if it is fixable?
