Most impressive. Did you lock the discrete GPU with grfxCardStatus during the second screen recoding? Also, if you're taking requests, could you resize a window (corner drag) and invoke Mission Control using only the integrated GPU?
Got a tip for us?

Wow, that's buttery smooth! Thanks a lot for making the video. Now I'm officially pumped for this release.
I did the first video with discrete graphics on I think was because safari was with many tabs opened (the verge, YouTube, twitch etc..) and that pumps de discrete graphics. The second video e can assure you that was recorded with integrated graphics (HD4000)
I will make a video for you showing what your requesting. Stay tuned.

Excellent. Incredible improvement. And factor in Quicktime screen recording adding unusual stress on resources; I'm truly impressed. Thanks jffluis.
That still looks laggy to me. Is it because it was filmed using a screen recorder and not an external camera?
Huge improvement, it is almost as if it doesn't exist. Especially when if you do a full screen button on a video and it basically creates a new desktop to put the video in. It sucks and slow but on El Cap, you almost don't see it at all. The update is worth just for this speedup.
By the way, netkas is saying Metal is not yet fully enabled for OS X rendering. http://forum.netkas.org/index.php/topic,11144.msg30972.html
It looks like we might not be seeing the entire benefits of Metal just yet and the GUI could potentially get quicker in the next few beta updates.

And the GPU is a GTX 670 which IIRC Apple hasn't shipped so I don't see a reason why they would bother working to enable Metal on a GPU model that never came with a shipping product.
Yea, we'll just have to wait and see. The way WindowsServer keeps eating up my CPU on El Cap feels like it is not yet optimized to the fullest. It actually took Apple 3-4 10.10.x updates to get it under 1%. Hopefully, it will be faster this time.

I noticed they've increased the integrated graphic card's VRAM up to 1536 MB. It may be one of the causes why the animations are smoother now.
I haven't encountered it yet in 10.10.4 so hopefully they haven't messed it up again in El Capitan.
Wow, I just installed El Capitan on my 2012 15" Retina Macbook Pro and I'm impressed how fluid everything feels. This is the best release yet for the Retina Macs. Even at the scaled 1920x1200 resolution running on the HD4000 graphics things are smooth. Obviously there are some bugs here and there due it being a beta but this is great. Resizing windows is smooth, launch pad at 1920x1200 is smooth, opening and closing windows is smooth.
There's still a tiny bit of lag when opening my Applications folder in my Dock. Other than that, everything is good.
Is there still a regression in performance after a few hours? I remember people mentioning a lags appearing after a few hours on Yosemite. Also, how's the performance compared to Mavericks?
I feel no noticeable difference in general UI performance between Yosemite and El Capitan on my 2012 rMBP.
Oh, where have I read this before...? This statement is in every thread about retina screens since like forever!!! Things will get better - but when...? The eyecandy-race will just continue and possibly will even a future 16 core MBP struggle with the future 900 dpi 8K screen. But it too will be faster, in future updates! Just wait!

The GUI is definitely quicker in El Cap (DB3 improved it from DB1 and DB1 was much quicker than Yosemite), we are getting the update we want. I see almost no lags in El Cap as long as I use the default Retina resolution.
However, the lag will never be fixed completely because of how scaling works on OS X. The only way it can get quicker is by getting faster and more efficient GPUs or by switching to Windows 10, which will always be quicker than OS X because it doesn't need to scale up and down to fit the monitor.
This is IMO not true: the GPU bandwidth even in the 2012 rMBP iGPU was greater than the requirements to scale to the required resolution. The problem was Apple's old graphics architecture and worst-in-class GPU drivers and OpenGL pipeline. Apple's OpenGL performance lags even open-source Linux driver implementations programmed by volunteers (see the numerous Phoronix benchmarks)!
The fact this is so much better in 10.11 should be significant evidence that the problem was with software not hardware! Apple dumps their terrible OpenGL implementation = most people saying how fast El Capitan feels on first generation rMBPs (which is what i have too).
