I don't get the same huge improvement, but there definitely is some improvement, ±2~7%. Might be somewhat bottlenecked in my setup, but idk for sure.

NVIDIA DRIVERS Quadro & GeForce Mac OS X Driver Release 346.02.02 Any idea or information regarding what this beta support is? Could it bring problems with setups using nvidia cards as external gpu?

I don't think any programming skills are needed to follow the guide. pkgutil should be available in all OSX. Also, I would update to the latest version of the OS first before doing anything.

Hey! Try checking Display Preferences and gather click the [Gather Windows] button, there should be 2 windows there On the main window try turning off screen mirroring and see if it helps; I had similar problems with Windows ( the monitor is black; no signals detected ) and turning off mirroring resolved it.

2012 13" Macbook Pro + GTX960@10Gbps-TB1 (AKiTiO Thunder2) Never booted to black screen in OSX, but randomly ( I can't figure out why ) boots to black screen with Windows 8.1.

Updating to OSX 10.10.3 1. Open App Store and install update as usual. Be prepared since you'll have your external GPU / Display not working. 2. Download the latest driver that is compatible with the latest OS. See Notes for extra info 3. Unpackage, modify the Distribution file inside the package, repackage, and install the driver. 4. Modify .plist files as explained [here]. /System/Library/Extensions/IONDRVSupport.kext/Info.plist /System/Library/Extensions/AppleHDA.kext/Contents/PlugIns/AppleHDAController.kext/Contents/Info.plist These 2 are modified when the OS is updated. The following are updated when Nvidia WebDriver is updated: /System/Library/Extensions/NVDAStartup.kext/Contents/Info.plist Don't forget to run sudo kextcache -system-caches 5. Run the following command to make sure the nvidia driver is enabled. After the OS update, the system would normally remove nvda_drv=1 parameter since it was (detected as) incompatible. sudo nvram boot-args="kext-dev-mode=1 nvda_drv=1" 6. Reboot and the eGPU should work. Notes 2.1. In this case, I checked driver updates in Nvidia Control Panel and it found an update. It automatically downloads and runs the latest driver installer, which, to my surprise, gave no "incompatibility" warnings ( the driver installer was not modified yet ). It should probably work fine, but just to make sure, I cancelled the installer and tried to find the latest driver pkg file. 2.2. At this step I found a neat way to find and download the latest driver. You can open [this] link to see the latest Nvidia drivers published. Use [this] to filter it to Quadro K5000 Mac compatible only drivers. 2.3. Apparently, while the drivers could be found in that page, the page regarding its details was not ready yet. I checked the Nvidia Control Panel again and found the driver version; 346.01.02f01. I then modified the other driver's download link to match the version number, and voila: http://us.download.nvidia.com/Mac/Quadro_Certified/346.01.02f01/WebDriver-346.01.02f01.pkg X.1. It seems you can force the system to use outdated drivers ( bypass the incompatibility detections ) by additionally editing the value of <key>NVDARequiredOS</key> in /System/Library/Extensions/NVDAStartup.kext/Contents/Info.plist with the current OS build version. Might be unstable; needs further check.

Thanks for the info! I have added some info regarding my experience on updating the WebDriver in the main post.

Windows Software Setup 1. Install Windows 8.1 with Bootcamp. 2. Apply optimus patch [tutorial]. 3. Run windows updates, download the latest Nvidia graphics driver [link]. 4. Reboot to windows with egpu plugged. 4.1. Turn off the system 4.2. Power the PSU and GPU 4.3. Power the Macbook 4.4. Do nothing; if optimus patch was applied, it should boot to Windows right away 5. Install the Nvidia graphics driver ( without any extras on custom installation to be safe ) 6. Reboot, following the details in step 4. 7. Configure windows to extend the display and use both monitors. 8. The system should be ready to use the eGPU. Troubleshooting » When booting to windows after the gpu driver was installed, the screen goes to black and never loads. - Boot to windows without plugging the eGPU - Uninstall the driver, try to reboot with eGPU again; if problem reoccurs: - Boot to windows without plugging the eGPU - Go to system32, search with "Company: Nvidia" as search parameter - Delete all files found, try to reboot with eGPU again. Make sure all the previous steps were done correctly, and retry installing the graphics driver. Known Issues Installing Nvidia 3D Graphics Driver seems to freeze the system when booting ( with black screen ). Installing the driver without it works fine

Connect/power GPU via PSU 3.1. Find and plug the 6/8 pin connector between PSU and GPU 4. Connect GPU and Display via HDMI 5. Connect Box and Macbook Pro via Thunderbolt 6. Connect the Akitio Box power adapter. Software Setup 1. Download and install (latest) nVidia CUDA Driver [here]. 2. Find and download (latest) nVidia "Quadro and Geforce Mac OSX Driver". 2.1. You can use the search feature on nVidia website [here] 2.2. Modify the search parameters until you found the driver, e.g. like [this] 3. Modify the driver to ignore system check and allow itself to be installed on any (incompatible) systems. 3.1. Unpackage the file with pkgutil, like so: pkgutil --expand WebDriver-343.02.02f04.pkg expanded.pkg 3.2. Navigate into the expanded package and edit a file named Distribution 3.2.1. Find and comment out the following two lines of code, like so: //if (!validateHardware()) return false; //if (!validateSoftware()) return false; 3.3. Repackage the file with pkgutil, like so: pkgutil --flatten expanded.pkg WebDriver-343.02.02f04-nocheck.pkg 3.4. Install the modified driver. 4. Modify several .plist files [tutorial] 5. Add boot parameter to enable the driver 5.1. Run the following code: sudo nvram boot-args="kext-dev-mode=1 nvda_drv=1" 6. Your system should be ready to use the eGPU. Using the eGPU 1. Power up the PSU and Display. 2. Turn on the Macbook Pro Updating Nvidia WebDriver 1. Download the latest version of the driver, unpackage, modify the Distribution file, repackage, and install. See software setup step 3 for details. 2. Modify /System/Library/Extensions/NVDAStartup.kext/Contents/Info.plist as explained [here]. The other .plist files should remain unchanged; check them if you are not sure. 3. (Don't forget to) Run the following command: sudo kextcache -system-caches 4. Reboot and the eGPU should work fine. Performance / Benchmarks Notes - You can normally boot without the eGPU just by turning your Macbook Pro on without powering the PSU/Display.
