here are the basic steps: reFit/apple_set_os.efi to enable Iris gpu-switch (integrated.bat) to select the iGPU / reboot install the iGPU drivers and run integrated.bat / shutdown -- connect eGPU and boot you should have 3 devices in Device Manager, with the eGPU showing an error icon disable the dGPU in Device Manager and run integrated.bat / shutdown boot with the eGPU connected, check Device Manager for 2 enabled GPUs open Task Manager, there should be a constant 10-15% CPU load from the System process Hibernate (a fix to remove the CPU load) Reboot and the CPU load will be gone, eGPU will work with Optimus! How to shutdown (this is important!) Enable dGPU in device manager gpu-switch dedicated.bat If you get a black screen on reboot, at any point, you probably used gpu-switch and selected a disabled GPU reboot into windows safe mode to fix this

@p3nzancef1ier@tre87@maarten@juniordiscart@Morv@LukeHero Here are the steps, I got it working,

I finally got it working, Optimus + eGPU to power the dGPU Macbook internal display. There's a slight performance impact from using Optimus, but that's to be expected. reFit/apple_set_os.efi to enable Iris gpu-switch (integrated.bat) to select the iGPU / reboot install the iGPU drivers and run integrated.bat / shutdown -- connect eGPU and boot you should have 3 devices in Device Manager, with the eGPU showing an error icon disable the dGPU in Device Manager and run integrated.bat / shutdown boot with the eGPU connected, check Device Manager for 2 enabled GPUs open Task Manager, there should be a constant 10-15% CPU load from the System process Hibernate (a fix to remove the CPU load) Reboot and the CPU load will be gone, eGPU will work with Optimus!

Source?

Hi @goalque, 0.96 works quite well on my 750m/Iris 2014, but can install this without using the web drivers? thanks. EDIT: What about on a Maxwell card, a GTX 970?

Has anyone tried the new Nvidia 358.87 drivers? They added this feature in Win10:

Here's the source of that image, if anyone's interested. Lots of TB3 specs included.

Just what I was looking for, thanks @rhx123

When TB3 devices are released, I assume they will be backwards compatible with legacy TB devices via an adapter cable? Considering they use a different hardware interface (USB3.1 vs mDP) what will the solution be?

@goalque Why's that?

I haven't had an opportunity to try them, but Intel just released new Windows 10 drivers for the Iris.

Has anyone got this working yet?

Just to confirm- This is working on the new El Cap GM (15A282a) with WebDriver-346.03.01b07. See my post

(Link) Overclocking: I used nvflash/maxwell bios tweaker to raise max temp target/power limit. The power limit is raised to a max of 175% but I really wouldn't recommend running it at that level. Download nvflash + maxwell bios tweaker + 175% bios (GV-N970IXOC-4GD only!!!) MSI Afterburner settings: Surprisingly, the little card is very stable at these settings. Raising the memory clock to 8GHz introduces some artifacts however. 100% vs 140% Powerlimit (FurMark) Big thanks to Tech Inferno Fan, goalque and the rest of the Tech|Inferno community!
