Please give us some details
- What version NUMBER of Lightroom are you using (go to Help->System Info)?
- What operating system version NUMBER are you using?
- What size monitor are you using in pixels (width and height)?
- Do you have the GPU acceleration turned on? (Preferences->Performance tab->is the "Use Graphics Processor" box checked?)
Lightroom CC 2015, latest update Creative Cloud
macOS Sierra latest update 10.12.2
Macbook Pro 13inch (New model with touchbar Late 2016)
LG UltraFine 5K monitor
Intel(R) Iris(TM) Graphics 550
YES I use Graphics Processor
Al brand new system so to say.
I don't want you to tell me you have the latest version, I want you to tell me the version NUMBER.
I don't want the monitor size in inches. I specifically asked for the dimensions in pixels.
Please turn off (uncheck Use Graphics Processor) and see if your speed improves.
Sorry DJ_Paige, but thanks for the reply!
LG UltraFine 5K‑display has a 5120 x 2880px resolution
When I switch of seems a bit better?
Should I switch off “Use Smart Previews instead of Originas for image editing “ also?
Smart Previews might help, give it a try.
You have a very large monitor in pixels, in my opinion, you will have to accept some tradeoffs; turning off the graphics processor will help some things but will slow down other things, please read GPU notes for Lightroom CC (2015)
Also, your CPU (2.9GHz Intel Core i5) isn't particularly fast by today's standards and a faster CPU would help, but I'm guessing you can't really upgrade the CPU on your new computer.
Thanks dj_paige, I'll look in to that.
My CPU is 3,3 GHz Intel Core i7
Okay, that's a faster CPU ... this particular problem you are having is most likely driven by CPU speed, but definitely try the things I stated.
