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

Same for me, 5.0.37 for months and still anoying artefacts and so on...

I can honestly say that while it *** u can't use the higher resulotions due to OSX ML inability to switch to the GPU, I still can work in the native resulotion (best for retina) just fine and I enjoy this amazing machine.

I do hope the engineers will come with an overhaul to OSX ML to fully support retina machines

You just came from moon ??? How can you enjoy in (best for retina) resolution, if everyone see a lot of lags ? graphic issues etc ... ? Are you extraterrestrial ?

I don't have any lag issues while in 'Best for Retina' (15" 2.6 with 8gig version), only when I use the higher resulotions.

are you kidding ? how it is possible ? you want to say that you can't see the same what I can ?

try to open Mail.app and select many emails you will see animation and this animation is working fast on your laptop ?

Do you have smooth animation in expose, mission control, different desktop switching?

That's redic.. I've tested over a dozen machines (5 of them mine) all of them have lag issues. The only time lag is reduced is when automatic graphics switching is turned off, meaning the intel graphics are not used - all machines have been set to best for retina display. Apparently you have the one lone computer that works properly in this forum.. Odd.

Hey guys, I just made a videos (uploading to youtube) for you to see (just like poidet showed) and you can judge for your self

Sorry for not uploading HD version i don't have wifi currently @ work

Seriously, this is like the 1000x times video's has been posted, also like the 100000000 non-constructive moaning post about how angry you are.. Just stop that nonsense, as this topic is becoming impossible to read anymore. If you have any new developments which could lead to solve this issue, please post. If your here just to let everyone know how angry or dissapointed you are, please stay away.

EPO,

yes I understand. But people has been frustrated for so long now about it.

Here is my 2cents anyway:

Ever since I owned Mac (A Mac Mini for few years), there used to be a real memory hog app: Dashboard.

Even if u swiped by mistake to the Dashboard (widget window) mac OS (X) would launch those widgets and take upto 500mb+- memory out of your system (more widgets, more memory). You can clearly see it in 'Activity Monitor' app.

Since I learned about it back than, everytime I got a new mac or reinstalled OS(X) I'd remove it (disable) completely.

In terminal:

defaults write com.apple.dashboard mcx-disabled -boolean YES

killall Dock

Those who suffers the lags try it, I know that I did it and I don't have any issues with lags anyway.

take a look on your video (Retina test 2) from 22 second

http://dl.dropbox.com/u/7017985/Screenshots/0o.jpg

do you see on the top of the screen... what is it ? icon blink, title is appeared.. what is it ?

poidet,

Yes, that's a redraw issue indeed when u open and close the app drawer.

However I don't have any lags like I pointed.

I don't have the lag issue anymore either. I fixed it bye the autocad method.

You can find it further back in this thread.

I have one problem though, it wont go to sleep with AC power in.

you really thinking that 2500 USD is not the reason to have good device without so many problems, mistakes, bugs etc .... ?

Now I see why quantity who complain is much more lesser than other

I just make small video, you can see how much HiDPI mode slower than Usual mode

Yes they did it faster than it was at summer, but there are a lot of problems with sleeping mode, with perfomance in GUI, sometimes you can see so many bugs that you can't imagine how they released it ?

I'm developer and using that machine for 8-10 hours per day, I know what i'm saying.
