Discussion in 'OS X El Capitan (10.11)' started by VMukhtarov, Sep 10, 2015.
I made a small video
What to do? Downgrade to Mavericks?
No.....upgrade to a new mac
I don't want to upgrade my mac because of unoptimised system. Why Windows 10 is faster than 7 and 8 but OS X becomes slower every year?
Do you have these lags on 2015 models?
I watched your video two times. Where exactly is this 'lag' you are talking about? Are you referring to the fact that resizes are not instantaneous? This is called 'animation'
Is there no "lag" at all with Mavericks on you Mac when you resize windows? Even on my 3.5 GHz core i7, there a very short lag. El Capitan is just a fast. On my older Mac, Mavericks is indeed better at resizing, but Yosemite was clearly the worst.
No, this is called an-n-nim-m-mat-tion.
I just installed the El Capitan GM Candidate on my rMBP2012 and it no longer lags, 60fps throughout the UI.
The system is unbelievably faster and more responsive. Even older apps like iPhoto load much faster and are way more responsive. Not only the UI is faster but the file-system may have had an overhaul among other areas.
El Cap on was vastly improved over Yos overall on a 2010 quad Mac Pro, especially with resizing - Night and Day. Overall system performance felt more responsive and faster, as well.
So you don't have lags like in my video?
Am using 2012 iMac, no lags whatsoever as seen from your screen-capture,
could it be the capturing process using up on the already limited gpu power?
I'm actually very impressed with the animations, especially quick-look and fullscreen toggle.
I checked new MBA, it has lags too.
Well.. maybe you need to update your eyes to support 60fps, I don't know..
Just telling you they're fine on both my 2012 iMac and 2013 rMPB.
The lag is there: some people notice it and some not.
Look at how VMukhtarov resizes window just pulling it to the right and than compare it to double click on title bar. There's huge difference but it doesn't render computer useless.
I guess it's due to use of some antiquated framework/method. The same applied to "About this Mac" that lagged terribly until they fixed it in Yosemite.
I tend to notice these things. A screen capture doesn't do justice, the video itself has low fps,
plug he's probably using GPU with < 1Gb, with that weight on, it's normal to see some lag.
It looks great on my iMac, just my 2 cents.
It’s been like that ever since Lion or Mountain Lion, I can’t remember exactly. Snow Leopard was the last smooth OS release for me, although El Capitan has improved everything quite a bit. However, I use a 2008 MacBook so I accept this. On a 2012 MacBook, I would not and I would certainly not accept it on a 2015 MacBook.
To cite you, if you don't notice the difference in performance between pulling window to the right and double clicking on titlebar, please:
1GB of VRAM is enough to drive advanced video games like Alien Isolation and many, many more. It's way more than required to drive simple OS UI.
What we're dealing with is some unefficient execution probably due to antiquated framework.
PS.: Maybe you're going to tell me that "About this Mac" was smooth for you before Yosemite? Yeah, it was probably due to not enough VRAM..
It takes significant gpu power to do a screen capture, do you even??
Well.. I tend not to spend hours and hours on "About this Mac" to witness the lag.
In an everyday environment, it's unnoticeable. After upgrading to 10.11, the response is even quicker.
If your daily work requires you to resize windows every hour and make a fuss about the frame-drop,
that's just sad.
Yet still despite screen capturing, OP can smoothly resize window to the right. Besides, GPU power =/= VRAM.
So from "no lag whatsoever" you've gone to "just ignore the lag". Ok, fine - I'm not wasting my time anymore.
OP has proven his point and no reality distortion field is going to warp it into non-existance.
The only thing that I find slow is shutdown.
It opens SO FAST. Yesterday I switched the computer on, reached for my mobile to check notifications and didn't manage to because the system already opened. Whoa.
Shutdown, on the other hand... first apps get unloaded, then the spinning wheel appears and hangs around casually for a bit, and then the screen goes black but the computer is NOT off for another... 20-30 seconds. That's a new feature in the GM for me.
No, it's due to the fact that resizing is a demanding tasks that requires a lot of redrawing by the CPU (the GPU isn't much used for that). The framework used is Quartz, which is not particularly antiquated (it is frequently updated). Apple could have done as windows XP did: without double buffering. It would be faster but with lots of redrawing artifacts.
On my 3.5 GHz i7 iMac running Mavericks, resizing a finder window with lots of columns is far from perfectly smooth 60 fps. The OP hasn't even said what Mac he's using, but if it's a MBA, 10.11 doesn't look particularly slow at the task, especially considering the CPU usage of the screen capture itself.
And to answer the OP's question: why don't you post the same video with your Mac running Mavericks? If you find it a significantly better experience overall, feel free to downgrade.
The resize animation appears to use an ease-in transition. Also, the layout updates happen at certain threshold. Together, this can create an impression of lag. But I don't see any proper lag in those examples (although Console can be a bit laggy sometimes). As an example of real lag, try resizing App Store (which btw. is much smoother in 10.11 than it was in any previous OS X).
Some things are still slow, while others are much faster.
I don't have any of this lag. For me El Capitan is a VAST improvement over Yosemite, and the GM for me is such smoother and more responsive than the previous Developer Preview. Apple really worked hard on El Cap IMO.
The App Store is still pretty laggy when resizing.
