Slow as it gets on Windows on Arm

[micha?_6392]

I have a Snapdragon X Elite laptop with both emulated Lightroom Classic and native Lightroom CC. I can't believe, but the native CC is sluggish when navigating the UI, applying changes, etc. whilst the emulated Classic version works great. Of course, the AI denoise and compute-intensive features are slow, but not sluggish.

Adobe, please, please please, work on the arm native version

I'm on

Windows 11

Lightroom C 8.3

Hey, @micha?_6392. Welcome to the Lightroom Community. I'll need more information to help you figure this out. Please share the system information from Lightroom under Help > System info > Copy and paste into a text document > Upload and attach here. 

As primary steps, try this:

• Unplug additional displays & use only one by default.
• Pause sync temporarily. 
• Go to Lightroom > Edit > Preferences > Performance > Use Graphics Processor > Set it off if it is on Custom or Auto. If this shows any differences, please check this article to troubleshoot further: https://adobe.ly/3uYiJo4

There is a conversation where we discussed how the CPU and GPU are being used with compute heavy tasks: https://adobe.ly/4k21rdL

Let me know how it goes. Thanks!

Thank you for your answers.

I don't use the external displays and had already changed the graphics processor settings. I just don't understand why the Lightroom Classic doesn't have the same sluggish UI as the CC..
