xps 15 9570 - Photoshop lag and slow performance issue

Hello Guys,
I am a graphic designer and i have been experimenting some lagging and slowness using adobe programs, specially photoshop.
(mostly when i open big files (120 mb) and applying filters (like hue/Saturation) or when moving groups of layers on my xps 15 9570, these are my specs:

- 8th Gen Intel i7-8750H Processor (up to 4.1 GHz, 6 cores)
- 15.6" 4K touch display
- 512 PCIe Solid State Drive
- Nvidia GTX 1050Ti with 4GB GDDR5
- 16GB Memory

has anyone experimented a similar problem? (other apps like cinema 4d and games like fortnite or shadow of the tomb raider work just fine).

Some people recommend doing a clean windows install, but i am afraid my xps performance may drop if when i reinstall the drivers i left out anything relevant installed originally by dell(my xps is not too bad compared too other ones so i am afraid that may change)

Thanks for the help!
