Hi

- Macbook Air Early 2015 running Sierra 10.12.6
- Aorus Gaming Box with a EVGA GTX 1050TI (via Apple TB2->TB3 adapter)

I used automate-eGPU for setup. At first everything seemed to work fine, whenever I connect the box during boot it starts up and framerates in benchmarks are greatly improved.

But I noticed that other parts of the system are a lot slower now:
- My WiFi connection is terrible whenever the box is connected (even without running anything on it). Browsing gets horribly slow and while pings usually are in the < 20ms range, with the box connected there are many timeouts and pings > 1'000ms.
- Also whenever I move the mouse with the trackpad the framerates in benchmarks drops significantly. If moving stops, framerates go straight up again.

Any ideas why this happens and/or how to fix this? I couldn't find others having the same problem.

Any help much appreciated, thanks!

What application(s) are you running when this happens? My guess is that and the eGPU are chewing up your system resources but it could be many different things. Also I would not be surprised to start seeing fewer and fewer Thunderbolt 2 Mac configurations work with eGPU. Starting with 10.13.2 the level of support seems to be dwindling. By the official release there may be zero TB2 Mac support for eGPU.

I would say if someone can reproduce this using a Thunderbolt 3 Mac and a card from the Radeon RX 580/570/480/470 series... without any scripts being active (i.e. built-in drivers)... then it's worth reporting to Apple.

Thunderbolt 3 Macs, Sonnet and OWC eGPUs, 4K Displays, etc

I have similar problem but its mostly caused by a plugged in usb hard disk to the computer or the egpu's USB port.

@ChippyMcChipset: I was only running the Heaven Benchmark on the eGPU, nothing else.

@jpme: Thanks, I can confirm that I can reproduce the problem to a lesser extent even without the eGPU connected, so I assume it is not the main/only part of the problem.
