Hi Guys, the video is laggy on iTunes where it has many pictures.
The lag does not happen on text only page, but on any application with many pictures. This includes:
iPhoto, iTunes, safari, etc
Based on the video, safari was loaded on text only page. This is why it s smooth.
But you can see it s lagging on Itunes with many pictures

----------



Hi, could you a longer video on page with many pictures please?
your video from 00:18-00:20 shows that scrolling on iTunes is laggy

Thank you

Yeah, here you go. Anything else you want to see?

Just got my 16GB Retina Pro in the mail today

And it's legitimately unusable even for simple web browsing with a single tab. The scrolling is so choppy I thought mine was defective so ran the Apple Hardware Test... clean bill of health.

It's seriously insane. Chrome Canary is a little bit better but even just "maximizing" the app store window seems to run at about 10 FPS, super jittery and choppy.

I'm going to spend a night with it and a few hours tomorrow maybe, but at this point it's looking like I'll just be returning it and waiting 6 months to see if they can get it fixed.

My guess is they HAD to announce it at WWDC, and the software engineers just couldn't meet the deadline even if the hardware engineers did.

It's literally worse than 1st generation netbook graphics performance slow.

* I tried all of this over the course of 2 hours both with and without the energy saver graphics switching option checked. I was so so so so so so so excited for this machine :(
 
Sad :(

Dang. So it's really not "better". I mean it's way better than mine is now, but still not really acceptable performance for a machine with this hardware.

----------

Sorry but all the differing opinions in this thread have confused me - has anyone experienced screen lag on the default resolution?

Yes. Yes. Yes.

There really isn't any issues with mine. I'm not sure what you're seeing, or if the iPhone camera induces some lag, but when I'm scrolling on my computer is razor sharp, precise, and fast.
 
FYI, I picked up a new Retina MBP, and am experiencing the same scrolling issues as everyone else in Safari. Safari 5.2 beta does mitigate it to some degree, but it's clear there's more of an issue. I hope that Mountain Lion's new Safari will fix the problem, but for now - there it is. Boo.

Mountain Lion's Safari 6 completely fixes the issues I had before I updated.

It's waaaay better than what I've seen in any other video till now. And even if it isn't perfect, I can live with that kind of lags....
 
Same here.

Same here. I'd be happy with that for now too ( though eventually I'd want it to get a lot closer to the performance of Windows on even a lower end laptop ), just to be able to have hope for Apple being able to pull this off. Why they went with a lower-end graphics card when there's better out there at bargain basement prices ( Best Buy has a $1399 laptop with the 2GB version of this card for example ) I don't know, maybe they couldn't engineer away the heat, but dang... 2880x1800 is going to need every advantage it can get especially since they're calculating a billion scalings per second.

thank you very much for posting the video.
It looks so much better than I experienced at Apple store. I might put mbp retina into consideration.

I could see that iTunes is still lagging vs latest standard Macbook Pro

if you don't mind, could you please help to do a video on the below site.. and flick faster?

thank you heaps.

sure, uploading now. Keep in mind that it really does look a whole lot better in person. The iPhone camera is slowing it down a little. It's really very fluid and fast.

Another test video showing some requested sites. This is on a 2.3 GHz/8 GB/256 GB Retina MacBook Pro with OS 10.8 Mountain Lion Developer Preview 4. Again, give it a few minutes to process the HD.

These latest ML videos look incredibly fluid to me. Seems like the issue is more software based than anything else. So we can hope for Apple to improve ML, Safari and iTunes in the near future and eliminate the problem entirely.

Thanks for your tests Ken.
 
Question

Glad I could help!

Hey Ken, thanks for posting those. Are you on the "best for retina display" setting? If so can you ( out of curiosity ) do a quick survey of the difference in performance for those sites if any set on the highest rez?

I've noticed that on the highest setting even tiny text is still super readable so my highest hopes are they'll figure out a way to make that work well in ML too. Thanks man.

All of the videos were using the "best for retina display" resolution and the automatic graphics setting on.

I haven't noticed and performance degregation when switching the resolution either up or down. Scrolling remains smooth, text is always readable. Non-retina apps like Word need an update, but they don't look terrible. To me at least, the non-retina apps look better at a scaled higher resolution, like 1680x1050. It really boils down to what resolution you prefer; seems like all scaled resolutions are native.
 
Hmmm. Still not convinced.
Itunes scrolling In latest standard macbook pro is quite smooth. I do a lot of photoshops, cant afford to have a lag on this.
I might just wait until 2nd gen before getting retina.
 
I went to the Apple store in Denver 3 times in the last 3 days. When playing with RMBP, I noticed severe lag when doing:
1.) Expose
2.) Swiping between spaces (very bad screen tearing)
3.) Scrolling inside the App store/Itunes
4.) and minor lag when maximizing windows (tried this on Eclipse Java IDE)

However, I went to a Bestbuy store a few hours back and noticed no lag or screen tearing issues when I played with their display RMBP.

Note both RMBPs were the exact same base config.

I also went to a best buy today to test some of the reported issues and did not find any problems with lag.
 
My Retina MacBook Pro looks about as smooth as the Mountain Lion video posted, and I am running the pre-installed Lion, with all updates.

I'm not really convinced that Mountain Lion changes a whole lot. Then again I never really thought it was that bad in the first place...
 
The update does fix lag- friend who got a rMBP said that his lag went away after installing the (relatively large) update.
 
I just tossed Mountain Lion DP4 on my 2.6GHz RMBP and figured I would also report my findings. Overall things seem worlds better than under Lion. Chrome scrolling is not only better, but I honestly think it's smoother than scrolling was on my 13' Air. Chrome Canary scrolling was good, but not as smooth as Safari, and got pretty bad on complex pages. Safari scrolling performance seems to remain pretty good even on complex pages.

Swiping sideways between spaces was smooth sometimes and jerky others. Using scaled resolutions made it even more jerky, but disabling graphics switching improved things noticeably. I noticed in Lion that changing the setting for graphics switching seemed to have no effect at all. In Mountain Lion it's very noticeable.

So I don't think we're totally out of the woods with Mountain Lion, but it's sure a hell of a lot better than Lion.

Thank you for posting. Very clear.
How s the performance on adobe photoshop? Imovie, xcode and final cut pro?
Is it possible for you to post video?

Thanks heapsss
