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

That's because not too many people have the maxed out model. Personally, I have a 16GB RAM rMBP but base hard drive (256GB). I have all the problems described. The real question is whether the folks testing out 10.8.2 are still reporting improved UI experience...

Is it better with the new one? I am wondering if the new shipments could be a little more mature.

Makes no difference... this isnt a hardware issue its a software issue. I have a new 2.6Ghz 512SSD with 16GB ram and so does my girlfriend they both have the awful UI lag. I've read a few posts of people with the 2.7ghz model having the same issue... Someone on this thread mentioned that the beta update for the OS did make the UI better so its a waiting game.

I just shared the interface lags what I have with new OS and new rMBP, can anyone amke the same test, do you see the same lags as me ?

here is in video you can see lags when i'm using two fingers to scroll to next month.

If i'm clicking on arrow to switch to new moth then it's switching fast and without animation, but if with animation everything come tooo slow. And nvidia was turned ON with help gfxCardStatus 2.2.1

please make that test with your mbp. Thanks.

Which model do you have? Is it the base model? When did you buy it? Looks very weird. The GeForce really should handle this animation, even it is on a super high resolution as on the retina MBP.

It is base model. And base resolutiin(means middle one). If I will provide my sn it will help to determine anything else?

I seem to have resolved the problem by using the gfxCardStatus App to force the use of the GeForce graphics card (discrete) at all times.

The drivers for the integrated card dont seem to be able to handle some of the UI effects at the moment. Either this or before performing the effect it was attempting to switch to the discrete card and the process of switching was causing the lag.

How long does your battary last with the descrete card?

I havent tested. I am almost always connected to the mains.

This is great news for an interrum fix. Can you post a link to the App for people having this issue to try?

Thanks!

Its not so true....yep descrete card work faster, you should not be a scientist for that. But its not enough. In my post above you can see how descrete card is working. Can anyone confirn the same issue, on base retina laptop?

Are you sure descrete graphics are active?

Maan this really keeps me away from buying this thing. Too bad, seems it's a big, bad and expensive joke on the apple community. It is unbelievable and not understandable how a company can really be that ignorant to their customers because of fame, since I believe it's apples 'fanbase' that brings most of the money. It's a slap in the face for those who baught in trust.

Finally after using it for sometime. I have to return it as it is really below starndard product and not expected from Apple. Really disappointing.

Hoping for next year Macbook Pro will be better....:-(

THIS IS HEAT BASED ISSUE. cold card hot chip, use the card FIXES IT. Cold chip hot card, use integrated, FIXES IT. gfxcardstatus is readily available just google it....

I would also suggest istat pro for dashboard to monitor your various temperatures, remember apple say use the rMBP on a cold desk with good thermal conductivity not on your lap.

(although it wouls be nice to get some decend drivers to resolve this issue in ML, pretty sure the fans need to run louder which is the problem for voice recognition)
