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

Hello all,

This might be too naive, but has anyone tried to connect to an external monitor and turning off the retina display completely? By this we can isolate whether the problem is with the display or son\mething else. Because I feel that macbook air shouldn't be faster than retina display pro( No offense Air users, and even then Air is too fast).

Worth a try.

Actually, I should elaborate a bit more in regards to Nvidia Cuda 5.0.59...usually when I wake my laptop from sleep (opening the clamshell display) the screen flickers blue and black for about 5 seconds before any image appears. After installing Cuda my screen comes on instantly. Plus I left the laptop unplugged all night and it's still at 100% battery charge. Safari, iPhoto and memory intensive apps seem a lot smoother especially when resizing the window itself. Are we finally onto something here?

What are Cuda and how does one download them?

Right now the public version of Nvidia Cuda is 5.0.45 for 10.8.3 support. Cuda replaces Apple video drivers with one's created and updated by Nvidia directly. 5.0.45 can be downloaded here: http://www.nvidia.com/object/macosx-cuda-5.0.45-driver.html

What are the benefits and risks when using the Cuda driver versus the one that comes with Mountain Lion?

@poidet - no improvements removing Flash, I tried this before.

If I give up Cuda, how do I install Apple's drivers? What's gonna happen if Apple launches a new driver update, it will replace the Cuda driver without problem?

I've downloaded the Cuda drivers and installed, but how do I know if the system's using them? Installation just ended and that was it. How do I check what drivers my system's using?

Before you install CUDA, backup your original Apple drivers located at System>Extensions and backup the following files:

GeForce.kext

GeForceGA.plugin

GeForceGLDriver.bundle

GeForceVADriver.bundle

NVDAGF100Hal.kext

NVDAGK100Hal.kext

NVDANV50Hal.kext

NVDAResman.kext

NVDAStartup.kext

Download a copy of OpenCL_OceanWave_Bandwidth_V161 and see if your framerate has improved or not. You should be getting anywhere from 135 to 170 fps according to their website.
Make sure you quit out of all your apps before running any benchmark tests.

Does anyone know how to install the CUDA drivers? I have downloaded the installed, but nothing has happened. Just finished the installation and didn't ask me to reboot, change settings, or anything.

Any ideas?

I do see a small improvement with the latest cuda drivers. Thats if i set the video card to Nvidia only.

But it still does'nt come close to how smooth screen window animations scale and move on older traditional macbook pro's and even Air.

So this is no fix for me.

It is obvious that somebody from apple reads our posts...because they are deleting posts they do not like:(

If they dare to delete those posts, why dont they dare to give us a statement on this insane lag, EVERBODY has got on a retina Macbook? Comon Apple do somthing, support the customers, give us at least some feedback or advice what to do whit this 3000$ faulty machine???

I couldn't agree with you more, since Apple has deleted more than a couple of dozen of MY messages, when all I'm trying to do is give us Retina MacBook users some sense of hope.
And, just to report, while you're able to read this, my MacBook Pro Retina has been doing quite nicely with the latest CUDA and "other stuff". I would say 50% less lag, 90% quicker restart and shutdown times and no more black/blue screens of death at startup and a lot less lego blocks. Once Apple release their "other stuff" you'll know what I mean.

I've "only" waited since december for this, but I bought this 15" to replace a iMac and run a specific software in fullscreen. That haven't been possible at all without severe annoying lagging, so I get mine rMBP replaced with a non-rMBP hi-res now.

That means even lower resolution and that really blows. Specially since some of you have such improvement with the new drivers now.
