LrC Performance Tab vs Nvidia App Optimization

Question

Lightroom 15.4.1 on Windows.As GPU I have an NVIDIA 4070 with 12GB of VRAM, latest studio driver  6.10.62.In the Graphic tab of the NVIDIA App I can choose to "Optimize" LrC, but if I do then in LrC settings under Performance tab it sets automatically CUSTOM under "Use GPU", option "GPU for export" is disabled and greyed out and it says I have only "Partial graphic acceleration".If I manually force AUTO under "Use GPU" than when i go back to NVIDIA App it says LrC is not optimized, and if I select OPTMIZE again than under LrC Performance it goes back to partial accelleration. Any idea?

Hey, @Giovanni Stoto. Welcome to the Lightroom Community. I'll clarify this for you.

The Auto setting is the default and recommended GPU mode in LrC. It lets Lightroom decide the optimal GPU usage per task.

The NVIDIA App applies generic game/app profiles that override per-application settings. For creative apps like Lightroom, these profiles can reduce functionality (e.g., disabling GPU export) because the profile doesn't fully understand LrC's internal GPU pipeline.

So, as long as you get to use the desired GPU acceleration, you may ignore the 'Not optimised' state.

Thanks!
