The included AMD Radeon Pro 580 - whilst pretty excellent for ‘flat’ gaming, hovers around the barely acceptable region for VR gaming.

After a lot of digging around, I updated the AKiTiO Node’s firmware here: https://www.akitio.com/firmware/node-firmware

Note: I’m only concerned here with using this in Windows, but this site has extensive tips to get it working in MacOS too.

Then I stumbled on the solution to get things working perfectly...

As well as the eGPU enclosure & card, you need an external monitor, as VR just won’t work properly without one(Oculus Home works, but not many games).

So, you’re in Windows, the eGPU box(via the TB3 connection) is fired up, your Rift/Vive is connected via HDMI directly into the eGPU card, and you have the external display also mirroring your iMac’s display, but VR *still* won’t work, when you fire up the games...

What you need to do, is go into the Display settings, scroll down to the ‘Multiple displays’ section and select the ‘Show only on 2’ option from the drop-down menu(which turns the iMac's display off), confirm the changes, and now, will VR(and non-VR) work properly, with the turbocharged GPU.

Yes I’ll do that later, when I get back from work.

@gregz0r, what about your promise? I would like to see some benchmarks of your system. Unigine benchmarks are a must.

Hiya, im looking at building a similar set up. Do you have any problems with Akitios PSU not being powerful enough for the 1080TI?

Trying to set up - iMac (Retina 5K, 27-inch, 2017) Radeon Pro 580 8 GB
With Sonnet Breakaway 650 & EVGA GeForce GTX 1080 Ti SC2 GAMING
