I see Bizone has a t2 one that seems to work, but from videos I seen osx doesn't support it, so you have to connect it to an external monitor first? I am so confused by this stuff.
What did seem to work pretty well, is on windows via bootcamp.
Where the 13" was around 10 fps or worse, on all settings ultra, it was 60fps and up on eGPU.
And quite importantly as well, offloading the stress on the cpu, the cpu goes up to 80c and fans a blazing, and then eGPU gets used, and the cpu remains around 50c, and fans dont kick in.
