Another thing, I didn't had this problem on my MBP that Is from 2011! It was not the smoothest experience ever and there was some choppiness, but nowhere near what I'm getting on this machine. Plus its 7 years older. On the laptop I had only the previews stored locally.
So, no one else has this problem? Slow scrolling on the new Lightroom CC?
Same Problem on 2016 MBP 15“ (best processor available, dedicated radeon graphics).
My assumption is, the problem is worse on Retina Screens. The Scolling in the Laptop itsself is really bad, but if you put lightroom on a 5K Display, you can scroll up and down some times, then lay back and watch the conputer executing the scrolling inputs the next 15 seconds.
I think Adobe does not care, as their Software usually is an UX Desaster.
Same issue on a brand new 2017 MacBook Pro 15", 16 GB RAM etc. Very slow/choppy scrolling.
Scrolling on my old 2011 MacBook Pro is nice and smooth.
Turning down the resolution definitely helps a lot!
Interestingly, the number of photos shown in the grid view does not seem to impact scrolling significantly, but screen resolution definitely does.
I am also experiencing this issue. Scrolling is unbearably choppy and most other actions are quite slow, this is all on a new 4K iMac. I see better performance on my 6 year old MacBook Air.
I can understand launching a product that doesn't replicate all of the features of the tool that it's replacing, but I can't appreciate launching something that doesn't even function properly.
Same here on a late 2015 5k iMac. All photos stored locally and scrolling stutters. The difference is night and day when compared to Apple Photos, both of which have similar library size. Disappointing that Adobe can't get this right when Apple's free program can.
6 week old MacBook Air (10.13.2)
3 week old iMac (10.13.2)
Neither has anything remotely close to what you experience.
Seems (IMO) that if something were wrong with the software we would all experience the problem.
The software doesn't change from user to user.
99% of the time problems arise, the cause is a system, and/or user settings of preference settings
