Subject: GPU not supported in Lightroom Classic – NVIDIA RTX 5070 Ti

Question

Dear Adobe team,I recently upgraded to a high-end workstation running Windows 11 (Business Edition, fully updated) with an NVIDIA GeForce RTX 5070 Ti 16GB, and noticed that Lightroom Classic 14.4 (build 202506051112) does not recognize or enable GPU acceleration.The app displays the message “GPU not supported”, and disables all GPU-related enhancements, even though:The GPU is fully recognized by OpenGL (GL_RENDERER: NVIDIA GeForce RTX 5070 Ti / OpenGL 4.6.0 NVIDIA 576.80).Photoshop CC 2025 detects and uses this GPU with no issue.The driver is up to date (version 576.80).I have tested multiple settings (auto / custom GPU selection, performance modes).This seems to be a listing issue, i.e. the RTX 5070 Ti is not yet whitelisted as a supported GPU in Lightroom Classic, despite offering full OpenGL and GPU compute support.Please consider adding official support for the NVIDIA RTX 5070 Ti in an upcoming update of Lightroom Classic.Let me know if you need logs or diagnostic reports (config.lua, agprefs, etc.).Best regards,Pierre MorelPhotographer – Paris, Francephoto@pierremorel.net

LR and Camera Raw don't whitelist supported GPUs. Try these troubleshooting steps:

1. Delete 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.
