10.9.1 and scrolling lag + UI lag
- Thread starter zeiter
- Start date
- Sort by reaction score
I don't see any changes. Apps which didn't lag (like Safari) still don't lag. Apps which lagged (like App Store) still lag. E.g. in Safari the scrolling is still around 50fps on sites like Facebook and The Verge (commonly used to illustrate scrolling lag). This is measured on a 2012 15" rMBP, base model. Mission control also seems to be the same - there is a short initial delay if you haven't used it in a while (and there are lots of apps open), after which it becomes very smooth again.
Better Performance Here
I have a late 2013 MBPr 15" and since upgrading to 10.9.1 have found a noticeable performance increase (swiping to show desktop and spaces, quick view of files by clicking space - general UI navigation stuff). I now feel like I am getting the performance I was meant to get with this machine (when I got it 2 months ago). PS - I only use 'best for retina'.

This was a major step back for me. Scrolling isn't exactly laggy, it scrolls the wrong window. Its fine right after startup but not long after I will be in Mail and want to scroll message view with the track pad and the message list view will scroll. Not only does the wrong window scroll, but instead of rubber banding after pulling down it continues to scroll until none of the messages in the list/inbox view are visible, they have scrolled off the bottom. Using tab, switching apps, doesn't help. The beach ball is back quite often. It was mostly gone after upgrading to 10.9.0. Worse yet, the whole machine completely freezes with 10.9.1. The clock even quits updating. Where was the quality testing before this release. I have used every version of Mac OS since 6.0. I really questioned whether all the good OS X developers were moved over to iOS after Snow Leopard. The quality hasn't been close to what I expect from Apple. But then they released iOS 7 and that indicated that the good developers weren't working on that project either. I love iRadio in iOS 7but its almost impossible to use because it starts skipping I can change to iTunes music I have loaded on my iPhone and its still skips. It usually requires a reboot. I know this post was just about scrolling but I use my macbook pro everyday for work and I need it to just work, like it used to.
10.9 offers undoubtedly better performance in HiDPI modes than 10.8 (I am seeing fps improvements of over 60% here, using the same hardware and same content). If its not the case for you, you might have a botched installation or some other problem.
I have no such luck. Even with a fresh install
This is very weird. Did you try SMC reset and all the other stuff?
Actually, yes. I tried zapping/resetting multiple times. Running Unigine yields a lowly 16.9 fps as a result, on a fresh install of Mavericks, which definitely seems on the slow end of things.
Just tried it at scaled 1920x1080 res. Using Photoshop CC resizing the window lags about 1/2 a second behind the cursor. Lags so bad while dragging that occasionally the beach ball appears.
Safari flies though. Doesn't lag at all while scrolling web pages. It's even smoother than my 2012 model.
This is the base haswell 2013 model with iris pro graphics.
then I have no idea what computer to get. The mac mini still has ivy bridge and hd4000 and the new macbook pro are sluggish and laggy with the programs I need the most (photoshop + lightroom)....I guess I'll have to go the windows 7 route...

Ask yourself this, though. How often do you resize the Photoshop window? I haven't resized it in weeks and when I do, it's for like 5 seconds and I go on with my work. It's such a rare thing it won't affect your workflow. The actual USE of Photoshop on a rMBP is excellent - it's plenty fast and snappy.
EDIT: I forgot to mention I use Photoshop in best for retina "non-scaled" resolution when I work. Never used it in scaled resolution except for that resize test, so I can't really comment on how it performs in scaled resolution during normal workflows. Somebody else with experience can chime in in that case.

Its clearly Adobe's bug. Yes, resizing a windows involves more work in a HiDPI mode - the application should be able to optimise it. Many applications are quite inefficient about resizing - they try to recompute everything for each single pixel they are being resized. Its quite wasteful of course - and while its possible to get away with it on a normal screen, it gets critical in the HiDPI mode and its 6x pixels. Apple API offers plenty of opportunities to optimise resizing - by tweaking what is displayed during a live resize. I fail to see how its Apple's fault if Adobe fails to use them.
P.S. I don't see much lag when resizing a Pixelmator window.
P.P.S. As noted above, its a bit weird to reject a computer based on a resize bug. Its not like your work only involves resizing windows, does it?
When you guys are working on Lightroom/Photoshop, which resolution are you using?
I am considering to purchase rMBP 13 for my Lightroom/Photoshop work on the road (I chose 13" for portability), but can't find a video or review showing if the UI will have lag when using Lightroom/Photoshop. Anyone can share some videos or probably feedback on this?
Note: I am planning to get the max rMBP 13"
