I am not sure what it is, but the beta that Apple released today has helped my UI lag considerably. I am running a 13inch 2015 MBP.


Both highest settings under Displays -> Resolution -> Scaled seem to run much better.

I am not sure what has helped, I know they removed the discoveryd process and put back mDNSResponder but I figured that would only help with networking. Maybe the UI lag is due to lag in accessing network resources?

I am not sure but this latest beta seemed to help. Anyone else notice this?
 
For me, the network stability is the bigger issue. Most places I have no problems at all, but there's a handful of networks that give me fits...
 
I can confirm that Mission Control appears to work significantly better when many (dozen+) app windows are present (previously it would often take a second or so for it to collect all the window data). As I haven't observed any other UI lag on my machine (2012 rMBP), no idea if there are other changes.
 
I was getting horrible lag even with the lowest of the scaled resolution. Now its much much better.

I was contemplating on getting Windows and running that since Windows 10 beta ran better.

This is a game changer for me. With the UI running nicer on Yosemite, i rather stay.
 
My 2015 rMBP is now liquid smooth and boot times are much faster too. It's about time!
 
Yeah I am not sure what they did but Yosemite is much smoother with this new update. Is there a way to tell if they changed video drivers? I am not sure what they did to help, its pretty sweet though.

Well its about time they get off their high horse and come back to planet earth...
 
I would like to see confirmation from others who have installed the latest beta so I don't think I am going crazy :)

Stick your Applications folder in the dock, set it to grid, and see if that stutters. On my 15" 2012 rMBP, it's pretty noticeable, both with the Intel HD 4000 and Geforce 650M.

Another test is to switch the Applications folder to List and see if scrolling is laggy as well. Also pretty bad on my machine.

They may have changed something else, I doubt that discoveryd was to blame for UI lag.

Yeah, thats an old bug, dating back at least to Mavericks. I guess its very low on their priority list (which would make sense).

I see no difference. Perhaps I should clean install my laptop.

Its a beta update, You'll still only get 10.10.3 and then you'll have to apply the beta update. I don't think a clean install will change things.
 
I would also like to note I still have "Reduce Transparency" Checked as well. I am not running defaults for Accessibility options. For those still having issues with the latest beta (not full reinstall of 10.10.3), do you have Reduce Transparency checked or unchecked?
 
Booo, the performance improvements disappeared within a day. Back to choppy. But with that update it lasted long than any other so far! Looks like I'm going to be keeping transparency off because my laptop is simply too laggy to work on with it enabled. I wish my 15" battery lasted longer :( Reboot didn't help with performance either. There's some sort of weird cache-driver bug interaction going on because the performance degrades so fast

Strange, my MBP is still performing very well. Even after a few days
 
Hi everyone, first post here... I just bought brand new 13" macbook pro 256 gb version yesterday. I tried and checked gui animations, hot corners before i updated 10.10.3. (Built in was yosemite 10.10.2). flawless... Then i updated it, it was even better, faster and smooter. Is there any possibility Apple took it into cosideration all the complaints and fixed something in their newer production date units?
