Q: Mountain Lion UI Lag on rMBP !!! (Let's Make this thread serious and hope for a fix)

You practically reached 60fps? You expect more?? 60fps on my rMBP is butter smooth! Unless we have discrepancy on what "butter smooth" should be. Incidentally, do you know what frame rates we should be getting with our rMBP's anyway?

Does anyone know how to get in touch with Intel development site? Or to speak to an Intel engineer? I'm pretty sure this is the key to the missing link to a better machine.

From what I have read is Intel sends their drivers to Apple and then Apple tweaks them to better fit the OS. Intel is supposed to be releasing a new Windows driver for Intel HD 4000 which will give a 10% boost in performance. From what people are speculating is the mac equivalent to these drivers will be the drivers released in 10.9 and won't come to 10.8 right away.

I've been experimenting with this issue for the past day and have installed Cuda 5.0.59, 10.8.4 and the latest dev release of Chrome.  I even employed a few GPU optimizations under chrome://flags.  All these adjustments did seem to make a subtle difference, but it's still not as smooth as I would like.  Sites like Facebook and TheVerge run just fine, but when I open a more intense site like Mashable it is still noticable.  Even Webkit can't handle that site as fluidly as I'd like.  Another good benchmark is a Flickr photostream.  I'm getting about 30-50 fps scrolling through mine, but it's a little choppy even at those frame rates.

I've recently been to the local Apple Store and tried several models doing the same tasks - load a web page, zoom, and scroll. My findings: both 15'' and 13'' retinas were worst, with gray rectangles slowly rendering, pausing for a second or two and then jumping to the end of the page. Resizing windows extremely stuttery. Next, I tried the Air which is also a bit stuttery, but it doesn't stop while scrolling and is smoother. Old Pros are fast. My HP Probook which is 2,5 years old is even faster than these non-retinas. So, my question is: since retinas are now very cheap compared to the prices a year ago, should I still grab one, or is not only scrolling, but overall speed of the laptop unsatisfactory? I mean, if even text input in Word stutters, I will not buy it.

No, i don't expect more, but i expect more homogeneity, yes i get good results in most of the tasks, but simply resing a window it's like **** broke loose and all came partying to my UI. Like you can see in this video i already posted (http://www.youtube.com/watch?v=zzyUjVp56Zg&lch), the blinking shows only in the video, because onscreen it is actually lagging like ****.

Hi guys, since Apple is PROBABLY going to announce a new macbook retina on WWDC 2013, maybe we could get a replacement!? I know there is a rule here in the EU, if your device is not repaired after the 3rd time of sending in you get a replacemant. If thath specific device is not being produced anymore, the company have to give you a device with the same specification and value.

My warranty expires on the 7th of July and I am thinking about to send in my macbook retina for repair just after the WWDC 2013.

An important question: Is the warranty period (which is 1 year for me) on pause when you send in the notebook for repairment? I mean, i do not use the device during that time? It would be stupid to send the device two times in and get it returned AFTER the 7th of July and not being possible to send it in a thrid time because the warrany expired.

If they actually CAN repair my notebook i would be the happiest person alive, if not, a working replacement should be expected...am I right?

PS: I am talking about the lag. Thats the only failrue i have on my rMBP basic. And i know many many sotries how people send in their Apple devices and got immediately a brand new device as replacement. Apple did not even try to repair it. That is what many people do and it works all the time. Maybe replacing is cheaper than repairing for some devices!?

I don't know what country you are from. But here in Norway we have a 5year warranty on consumer goods.

@TheWaveable

Wow, that's amazing and unbelievable:) I have never heard that a state law can determine the warranty period for a manufacturer!?

I am from Austria and the standard warranty period is 1 year for Apple products, with apple care plan it is extended for 3 years.

Has anybody had experience with replacement prodcuts with Apple?

I would like to replace my retina to new retina with new one warranty year, but I'm thinking they will do it

btw, sometimes, someone saying that discrete card is working better and bla bla bla... yes this is true, but from my side, I could say that with discrete card my fan makes more noise, it means that whole body become warmer And why, guys, why I should pay for two cards and use only one, because another almost unusable ?

I agree poidet. I want to be able to use the Intel when on battery to conserve power. I shouldn't have to sacrifice battery time to get the performance I expect from a machine this expensive.

Well it looks like they're adding "accelerated scrolling" to Safari in OS X 10.9.  Hopefully this addresses the issue.  Too bad we have to wait till fall.

Seems like 10.9 would be the fix for most of UI RMBP problem. OS X Mavericks looks good by the way.

@vitor_mfc

What makes you think, that 10.9 will fix most of UI RMBP lag...what did they say about that on WWDC 2013?

@ raif_

There was enough talk to prove major enhancements in scroll, battery life, system operations and more. I am a developer and I am very optimistic that Mac OS X Maverick will finally fix all Retina Macs. Once Maverick Beta is available I will install it and see if what was presented at the WWDC holds true.
