11G15 10.7.5 beta update

GPU drivers are exactly same version as in MBP2012′s update pkg.

At least you can use 10.7.5 beta update to get drivers installed the Apple’s way.

Example of ThunderBolt tandem with eGPU

We all was wondering how will apple implement TB on new macpro… well we can continue wondering.

Here is example of possible solution…not

They use lucid virtu mvp i-mode to pass rendered image from external gpu to internal gpu which is connected to TB.

No matter what, it gives performance hit (and lga2011 xeons doesnt have iGPU anyway).

Still interesting video to watch.

MBP 2012 osx news roundup

1) ivy bridge support in kernel
2) geforce gtx6xx drivers, working
3) ati drivers, 69×0 working in macpro
4) intel hd 4000 drivers, not tested
5) usb3 drivers for z77, working

6970 working in Lion

With no patch, msaa works.
All you need is drivers from MBP2012 and three more frameworks from mbp2012:

/System/Library/PrivateFrameworks/GPUSupport.framework
/System/Library/Frameworks/OpenGL.framework
/System/Library/Frameworks/OpenCL.framework

So again, 6970, no coldboot bug, msaa works, itunes doesnt panic, whooooo
smalluxGPU opencl bench causes KP.

Follow the progress here

P.S. you can even get kepler working in Lion same way.

How Retina macbookpro works with screen resolutions

Seems pretty simple
System settings allows you to select 5 screen sizes – 1024 x 640, 1280 x 800, 1440 x 900(default one), 1680 x 1050, 1920 x 1200
Once you select one, it retinezes it (x2 on both dimensions) so you get 2048×1280, 2560×1600, 2880×1800, 3360×2100, 3840×2400

then it upscales (in case of first two) ot downscales(in case of last two) the image to fit 2880×1800.
So blur (in case of upscale) and lost pixels (after downscale) are not that noticable when pixels are small (220 pixel per inch).

MBP2012 ati drivers fix cayman coldboot bug

I’m able to boot 6970 into lion right from cold start, using mbp2012 update’s drivers

We just need to hunt down opengl && opencl frameworks from 2012 macbooks and cayman is done for lion, (maybe a little patch will be needed, but still, no coldboot bug is great news)

And GTX680 works in OSX

About ML DP4

1) kepler drivers present!
2) ATIRadeonX3000.kext is missing, completely replaced by AMDRadeonAccelerator.kext now, which still has cold boot bug and needs a patch for a kernel panic.

Here is your kepler drivers

Here is link to software update for new macbookpros, which I guess nobody has yet!
and guess what, it has NVDAGK100Hal.kext !
