Some Things about OSX 10.11

Metal is available on compatible nvidia devices (not checked ati yet) with both osx driver and official webdriver.

But metal is still not used to render GUI on nvidia (it’s used only on intel igpus).

And as I mentioned previously, final webdriver brings metal support to Maxwell, now just to find what it can be used for.

We have eGPU subform openned

Btw, we have eGPU subform now at to tell more about using eGPU in OS X via ThunderBolt

10.10.3 brings better support for 5k

Before 10.10.3, to get 5k dell display to work one needed to have nvidia videocard with two display-port outputs, special boot option and powercycling of display after bootup was needed.

since 10.10.3 there is no more need for last step (powercycling display). Your 5k display will boot straight into 5k desktop.

10.10.3 brings 5k support to 2013 MacPro, there is no bootscreen tho. No special bootoptions needed, just plug and play, just no bootscreen.

As for nvidia, you can have bootscreen there, mac edition of gtx9x0 needed (or titan x, gta v is coming).

Dell 5k’s display have two inputs, one is single DP link for 4k output, another one is double DP link for 5k. Connect all three into card, you will have bootscreen in 4k and desktop in 5k.

GTX TITAN X already works in osx

Great new from our friends in California..

10.9 vs Win

I recently discovered heaven 4.0 for mac supports tessellation on OSX 10.9. So I decided to make a comparison of windows and osx drivers using same benchmark with same preset.

Using 8 Core MP3,1 and GTX Titan card, secondary ati 2600xt for boot display. For windows using latest whql nvidia driver.
Here are the results:


Windows OpenGL

Windows DX11

OSX drivers are 22% slower than windows opengl and 26% slower than windows dx11

Better Nvidia news

Nvidia drivers from 10.9, GeForce.kext has mentions of three geforce generations in it’s Info.plist

GF100 (old fermi cards)

GK100 (current kepler cards)

GM100 (future Maxwell cards)

This means they started writing drivers for maxwell, and it means samples already exists.
