My 2009 24" iMac is working quite well on this, I must say.

Great to hear. I also have a 2009 Imac (but base model + RAM maxed out).
Did you run Yosemite on this machine prior and how does it compare to 10.11?

super smooth on my 2012 rMBP as well. Even the mouse cursor itself feels smoother and more responsive (anyone else think this, or psychosomatic response going on here haha?) Incidentally my razer software no longer detects devices properly.
Looking to test some blizzard games (HOTS SC2:LoV Beta), of course the real fun will be if/when blizz updates their games to support Metal

Hi, please tell me about the performance of SC2 on El Capitan!!!

The main question is what GPUs are Apple going to support for this new graphics speed-ups in 10.11?

Considering how utterly awful Apple's GPU drivers and OpenGL implementation have been, we'll need to see how it can manage to deal with this across GPUs...

And will Apple just abandon OpenGL for those apps who cannot commit to rewrite for new APIs and lose cross-platform consistency...

running DP1 on my new 12inch Macbook (base model). Its running really smooth and fast. I am very impressed with how smooth switching Apps is. As well as Mission Control.
Animations are fluent.
Finally my stable fast WiFi connection back after many many speeddrops in Yosemite 10.10.2/10.10.3

Again, for a DP1 I am very satisfied!

Someone on a Hackintosh forum posted that Netkas has said:

"This info comes from metal driver availability, not from real test

Metal supported card families:
Nvidia – GeForce gtx 4xx and newer
Intel – HD4000 and newer (ivy bridge and newer)
AMD – HD7000 and newer."

Let us know how game peformance is when you test it, including Starcraft 2?

If this OS shapes up and proves to be a massive change of speed and performance then I hope they don't keep doing new versions every year. I'm scared they will go back to dumping features without keeping performance in high priority.

They really should keep annual updates but move to a release cycle something like Intel's "tick-tock"

Runs incredibly smooth on my nMP with multiple screens. Everything is faster and smoother than OS X has ever been, and I've been using it since 10.0
In contrast, Yosemite was unbearably slow, especially the UI animations.

The biggest change I noticed is on my 15" rMBP driving a 4K display. I have the display set to "looks like 2560x1440" and while general use was great, it was a bit choppy on some animations (particularly the Mission Control one) and some websites (particularly the Apple Retina iMac one).

With DP1, it's buttery smooth all the time :)

folks, i have been testing this since yesterday. so what to say? speed improvement overall, safari very snappy with the web pins, small glitches in UI.also system font is a bit tweaked like watch font. (the same goes for iOS 9),new mission control works pretty much.
soft:
adobe CC much faster (Ps, Ai, Mu)
little snitch not working yet
so far so good. :)

That's risky, make a image backup of your Yosemite partition. 10.11 is DP1 and thus may have some stability issues.

I know. ;) I have been making backups for years, regardless if it's a beta or final release, with TM and SuperDuper. It's about saving the data. I was trying to install it on another partition but Disk Utility would allow it since it's a logical volume and I have Windows installed.

Thanks pollaxe, if this is true, that is a lot of hardcore driver backend code across three vendors across multiple generations to deal with. This list does not align with the hardware requirements for 10.11, there are several machines with cards older than that list (Older Mac Pros for example), I assume they fallback to using an OpenGL backend...

No, its really not, you just don't understand OS X memory management.

Yosemite caused my laptop to use swap .... and it has 8gb. And I was just web browsing using Safari. That's something that shouldn't be defended.

So far, it hasn't happened yet with El Capitan.

I guess I'm the odd one out here, but the UI is incredibly laggy for me. Mid 2012 MBA, 1.8GHZ i5, 4GB RAM.

Blizzard should be updating for Metal support. Their logo was up there in that screen of companies Apple was working with to bring Metal to their products.

*EDIT*
Blizzard is in fact working to bring Metal to their games. There was a blue post in the WoW Mac forums stating that they didn't have an exact date but they are for sure adding Metal.
