Lightroom CC is slow on brand new Dell XPS 15 9500 up to date

[Eorlejeune]

Hi, 

I just bought an new XPS 15 9500 and I'm using Lightroom CC on it.

Sadly the app is incredibly slow regardind scrolling or opening or closing side panels...

All my drivers and apps are up to date, evereything on my computer works more than very well, only Lightroom CC is lagging (not even Photoshop).

I tried disabling GPU acceleration (worse), force high-performance GPU (nothing changed)...

Thank you for your help!

My configuration:

- Dell XPS 15 9500

Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz 2.59 GHz
RAM 16,0 Go

SSD

4k screen

- Lightroom CC 4.2
