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.
Instead of continually asking anyone complaining of LR performance for specs, let us just acknowledge (and wish Adobe could acknowledge this more thoroughly) that LR performance on new Macbook Pros is pathetic. More than than, it plain sucks. I have just purchased a new Macbook Pro 2017 with top spec (3.1 Ghz CPU, Radeon Pro 560 4Gb graphics) and LR is UNUSABLE for any professional work. The develop sliders lag, the Develop preview updates like 2 times a second at best, or once per second while using sliders to change settings like WB or exposure.
One does not need to go further than Library module: It cannot even browse from one pic to the next in Loop mode, or scroll the thumbnails in Library mode without hick-ups, jerks and lags. I mean can they look at how apple's own PHotos app scrolls and browses the pics, scratch their heads and finally do something about actually USING the hardware that Macs provide!
LR is slow both on the built in Retina display, and on my LG Ultrafine 5K - with zero difference in speed. Which makes me suppose that the GPU acceleration does not work at all (and I can confirm that switching GPU support on or off in preferences does not make any appreciable difference).
I tried switching on the use of smart previews for editing - that does not help either.
All that on brand new top spec Apple machine, with fresh Mac OS High Sierra and fresh install of Adobe Creative Cloud apps!
Wake up, Adobe, and concentrate on mac platform performance instead of being obsessive ripping off customers with subsriptions!
alexandrec16003235 or maybe we could acknowledge that MacBook Pros are not designed for Lightroom, and we need to have Apple put out a machine that is powerful enough to run LR.
Wake up, Adobe,
But anyway, we are not Adobe here in this forum, we are just other LR users who can't change the design or programming of Lightroom, and you are wasting your time here, you need to contact Adobe and not the users in this forum.
