UI GPU Acceleration Disabled on RTX 5080 in Lightroom Classic 14.4

Question

Hi Adobe team,I'm running into an issue with Lightroom Classic 14.4 (internal version 17.4x2272) on Windows 11 with an NVIDIA RTX 5080 TUF OC (16GB). The GPU is fully functional and properly recognized by the system, but Lightroom Classic will not enable GPU acceleration for UI/display rendering. the checkbox is present but grayed out in Preferences > Performance.Here’s what I’ve confirmed and tried:GPU driver: Latest Studio driver, clean-installed via DDU.Display: Single 4K144Hz monitor, tested also at 60Hz.Monitor is connected directly to the RTX 5080, not via dock or iGPU.iGPU is disabled in BIOS.Lightroom Classic is using the GPU for image processing and exports (denoise, enhance, etc.), but not for display acceleration.I’ve deleted Camera Raw GPU config files, reset preferences, and tested with logging enabled (-crlog -crgpusniffer).In the generated Camera Raw GPU Log.txt, Lightroom correctly identifies the RTX 5080 and confirms all feature levels and shader support, but does not attempt to initialize UI acceleration. There are no gpu_ui_* entries or any log lines referencing UI compatibility or failures. It simply skips it.Example from the log:name : NVIDIA GeForce RTX 5080DedicatedVideoMemory : 16660824064MaxSupportedFeatureLevel : 0x0000c100HighestShaderModel : 0x60My assumption is that the RTX 5080 has not yet been whitelisted or tested for UI acceleration in Lightroom Classic and is being silently skipped. If that’s the case, could you confirm whether support is planned for this GPU in a future Camera Raw or Lightroom Classic update?Happy to provide full logs if needed.

Adobe does not publish white lists or black lists of GPUs. There have been a handful of other reports here in the last few months of people struggling with the RTX 5000 series. A couple more troubleshooting steps:

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

2. If that doesn'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.
